Complete Guide to AI Tool Access

01Scope and How to Use This Handbook

The guides page on this site answers the first question: how do I get started? Sign up, pick a plan, grab your subscription, import it into a client, verify the connection — five steps, one path, and you're done. This handbook tackles a different class of problem: the connection is up, but AI tools still misbehave. The page loads but says your region isn't supported. An answer stops halfway through. The completion plugin in your editor spins forever. API calls in your pipeline time out at random. These aren't about whether you can connect at all — they're about whether the target service trusts this path and whether it can stay up for a long time. That deserves its own reference page.

Who this page is for

The first group is web users: the chat page opens, but sending a message returns an error, or the answer cuts off halfway. The second is account holders: login works, but the service says your region is unavailable, or sign-up keeps failing. The third is developers: model calls from CLI tools, IDE plugins and CI pipelines time out, get their connection reset, or hit rate-limit warnings. These three problems have completely different causes and different fix orders, so this handbook is organised by cause, not by tool.

Do these three things first

If you just want to get back to work, skip the theory chapters, triage with the three steps below, then return to the relevant chapter:

1. Check your current exit region — does it match the region the target tool requires? Most 'region not supported' messages come from here.
2. Switch split routing back to rule mode — global mode sends traffic through the route that shouldn't be there, which makes abnormal-activity flags more likely. See Chapter 05.
3. Reproduce the issue on a different route type — if the symptom disappears, it's the path; if it stays the same, it's the account or the region. This one check saves most of your debugging time.

Terminology

This handbook uses five terms throughout, so let's fix their meaning. Exit IP is the source address the target service sees on the network, not your device's address on the local network. Region check is how a service infers where you are from your exit IP, account details, payment information and similar signals. Long-lived connection is a channel kept open for the duration of one conversation; AI tool output depends heavily on it. Streaming output means the answer arrives token by token rather than all at once after generation finishes. Split routing rules are how a client decides which traffic goes through a route and which connects directly, based on domain or region.

What this handbook leaves out

No version numbers or release dates for specific tools — that information changes fast, goes stale quickly in a handbook, and ends up misleading readers. No third-party speed tests or scores, because measurements taken at different times, on different routes and different carriers aren't comparable. No promises of 'always available' — network conditions change on both sides, and any tool may adjust its policies. Where figures about this service are concerned, only on-site facts are quoted: 100+ countries / 190+ routes, unlimited devices, a 30-day no-questions-asked refund, monthly plans from ¥9.9, and data packs that never expire.

02Why AI Services Are So Sensitive to Network Conditions

The same route browses ordinary websites without a hitch, yet throws errors constantly with AI tools. That's not an illusion: AI services raise the bar on three levels at once. They need to work out who you are (risk checks), where you are (region checks), and they need to hold a connection open for anywhere from tens of seconds to several minutes (long-lived connections). Fail any one of the three and the symptom is the same — 'it doesn't work' — but the causes are entirely different.

IP risk checks: the 'identity' of your exit address matters more than speed

What an AI service sees is not your device but the address block your exit IP belongs to. Address blocks have history: how many accounts have used them recently, whether they've produced abnormal requests, what kind of network they belong to. If a block suddenly sees a flood of new sign-ups or high-frequency requests, the service often downgrades the whole block — and your own usage, however normal, gets caught up in it.

This is the line between 'can connect' and 'is trusted'. Connectivity only proves the path works; being trusted also requires your exit address to look clean, stable and clearly located in the eyes of the target service. So when choosing a route, don't just check whether it connects — check whether it's shared by a huge number of users and whether it stays in one region over the long term.

Region checks: three addresses need to line up

AI services usually pull region signals from three places: the region on file when the account was created, the billing region used for payment, and the exit region you're currently browsing from. The web app generally goes by exit IP; payment and subscription go by billing details; some tools write the region from first sign-up into the account itself. When the three disagree, the typical symptom isn't a flat refusal — it's the half-working state where the home page loads but the send button returns an error.

The fix is simple: keep your current exit region consistent with the region you used to sign up and pay. Don't use one region's route today and another's tomorrow, and above all don't jump between continents shortly after logging in.

Long-lived connections and streaming: one blip and the whole answer dies

An ordinary web request is ask-once, answer-once — over in a few hundred milliseconds. An AI conversation isn't: a single prompt can run for tens of seconds to several minutes while the server keeps pushing content to the client. This channel puts three demands on the path — low packet loss, stable round-trip latency, and no premature recycling of idle connections by the address translation in between. Fail any one and you get text that stops mid-sentence, or a long spinner followed by a prompt to regenerate.

So for AI tools, the measure of a good route is whether the connection can stay up for a long time, not the peak number on a speed-test page. A route with a modest peak but almost no jitter feels noticeably better than one with a high peak that stutters every ten seconds or so.

Encryption and interference from middleboxes

Another class of problem happens during the handshake: some networks interfere with the handshake of encrypted connections, so the connection is reset the moment it's established, or it takes several retries to get one through. This is easily misread as 'the route is too slow', so people keep switching to faster routes and never fix it. The way to tell: look at when the failure happens. If failures almost always occur right as the connection is established rather than mid-transfer, it's most likely a handshake issue — change the route type, not the speed.

03Availability Requirements for Major AI Tools

The table below sorts common tools by three columns — how you access them, what they require of your exit region, and what they require of path stability. Note that these are general patterns at the access level, not claims about any tool's current policy; go by whatever the page tells you at the time.

In the table, 'supported region' means the tool's officially supported scope of use; the exact scope changes and isn't fixed in this handbook.

Web, client and API are three different paths

For the same tool, these three paths have different network requirements. The web app is the most likely to be stopped by region checks, because it carries browser fingerprints, cookies and your exit IP all at once — the most signals to judge by. Desktop and mobile clients often have their own login state and endpoints, so they may behave better than the web app, or be more sensitive because they hold more long-lived connections. The API uses a separate endpoint and usually skips browser-level checks, but it has its own requirements around request rate, key ownership and exit stability.

That means 'the web app won't load' doesn't mean the tool is unusable. When the web app errors out, try the client or the API once to narrow things down: if the client works, it's a region check on the web side; only if the client fails too do you need to look at the path.

How to use the table

Treat the table as a triage sheet: find the row that matches how you access the tool, then read what that row demands of region and path. If both columns are demanding and you're on a direct-connection route, switch to a dedicated line first; if only the region column fails, just move to a route in the right region — no need to overhaul your configuration.

What if a tool isn't in the table?

New tools appear all the time, so no table can list them all. For an unfamiliar tool, ask the same three questions: which regions does it support? How long does one interaction last — seconds or minutes? Does it have its own client or API endpoint? Answer those three and the direction is basically set. For more route types and regional coverage, see the nodes page.

04Sign-up and Login Checklist

Many 'it doesn't work' failures actually happen at sign-up and login; the symptoms just don't surface until you start using the tool. This chapter pulls out the first half of the account lifecycle, because once an inconsistency is on record there, it's hard to undo.

Keep sign-up and usage in the same region

Whichever region's network you used to sign up, keep accessing from that same region afterwards. Some tools write the region from first sign-up into the account, and even after you change your exit they still judge by the original one. Signing up in one region and using the tool in another is the most common combination behind account flags. If you really do need to change regions, stay stable for a while first rather than jumping back and forth.

The simpler your sign-up details, the fewer things can go wrong

Every field in your account details can become a basis for later checks, so the more you fill in, the higher the chance of an inconsistency. MeyeVPN's own sign-up flow is built on that idea: no email address required — a username and password are enough, and one less step means one less chance of a mismatch. The same lesson applies when you're reading other services' sign-up flows: fill in as little as you can, and don't leave address details in your account that contradict the region you normally use.

The three checks most likely to fire at login

• Device and browser fingerprints: logging into the same account from wildly different device environments in a short window triggers extra verification.
• Region jumps: when the exit region of your previous login and this one are far apart — the most typical trigger.
• Abnormal frequency: logging out and back in repeatedly, or retrying the same action several times in a short window, counts as abnormal frequency.

The fix isn't complicated: do your main logins from one regular device; when you need to change regions, log out first, switch routes, then log back in rather than switching while logged in; and when you see a verification prompt, complete it as asked instead of retrying immediately.

The right order for verification steps

With email codes or CAPTCHAs, order matters: confirm your current exit region matches your sign-up region before you start verification; don't switch routes mid-verification; and if verification fails, wait a while before retrying — rapid retries usually make the wait longer. CAPTCHAs are sensitive to latency, so if one keeps failing to load, switching to a route with steadier latency beats refreshing over and over.

Payment and billing region

Payment is another important region signal. MeyeVPN supports Alipay / WeChat / USDT, and you don't need to enter a billing address — which removes one source of inconsistency by itself. With other services, if they ask for a billing address, keep it consistent with your sign-up region; avoid a situation where sign-up, billing and usage are all in different places.

Common messages and what to do

05Using the Web App and Desktop Clients

Once the path is up, the two things most likely to go wrong day to day are stale region state left in the browser and the wrong split-routing mode. This chapter follows the order you'd actually use them in.

Browser cache and cookies 'remember' the old region

On your first visit, the web app writes its region verdict into a cookie or local storage. After that, even if you switch routes, the browser may keep using the old result — the route is already in the target region, but the page still says it isn't supported. The order to fix it: switch routes → reload the page → if that still doesn't work, clear that site's cookies and local storage → reload. A private window is a quick way to confirm: if it works there but not in a normal window, stale local state is almost certainly the cause.

Split routing: global mode vs rule mode

Global mode sends all traffic through the route; rule mode sends only matching traffic through it and connects everything else directly. For AI tools, rule mode is usually steadier: local and LAN access isn't affected, and the exit address stays cleaner because unrelated traffic isn't inflating its request rate. Switch to global mode only when a rule doesn't cover the target domain, or when you need to check quickly whether the route itself works.

Four steps for a broken stream, in order

1. First, check whether you switched routes: switching mid-conversation rebuilds the connection — the most common cause of a dropped stream. Keep the route fixed during a conversation.
2. Next, check power saving or sleep: phones and laptops may suspend networking when the screen goes off, and the long-lived connection dies with it.
3. Then try another route in the same region: if several routes in one region all drop, suspect your local network rather than the routes themselves.
4. Only then consider changing region: a new region changes your exit address and may trigger a fresh account-level check, so leave this step for last.

Mobile clients and background keep-alive

The most common cause of disconnects on Android isn't the route — it's the system's power-saving policy killing the client process. The fix is to whitelist the client from battery optimisation, allow it to run in the background, and keep the screen on during long conversations. There's a more detailed comparison in Android background keep-alive and power-saving policies, tested, and the first-time setup steps are in the complete Android client guide, from install to daily use.

Using several devices at once

MeyeVPN doesn't limit how many devices can be online at the same time, so there's no need to log in and out across machines to save device slots. That said, running high-concurrency jobs on several devices under one account isn't a good idea either — with the same exit address, the request rates add up and rate limits get easier to trigger. Chapter 08 covers this in more detail.

06API Calls vs the Web App: Different Needs

API calls and the web app use two sets of endpoints and two sets of rules. Web failures mostly come down to region checks; API failures cluster around timeouts, concurrency and keys. Understanding them separately saves a lot of wasted debugging.

Different endpoints, different risk rules

The web app uses browser-facing endpoints and carries cookies, fingerprints and more; the API uses program-facing endpoints and carries only a key and a few headers. So the API usually isn't blocked by browser fingerprints, but it's more sensitive to request rate and to whether the key's account is in good standing. If the web app works and the API errors out, suspect the key and the rate first, not the region.

Timeouts and retries

Set timeouts explicitly on API calls rather than relying on defaults. Defaults are often too short, so long text generation gets cut off early; but set them too long and failed requests tie up connections for ages. The safer approach is separate timeouts for the connect and read phases, and limited retries only for idempotent requests. Retries need backoff — rapid retries turn one occasional failure into a stretch of rate limiting.

Concurrency and rate

Set concurrency by the rate your account allows, not by what your machine can handle. For batch work, holding concurrency at a level that finishes reliably saves more time than pushing to the limit and failing constantly. If the workload really is large, serialise it through a queue and control the rate at the queue layer, instead of letting several scripts fire requests independently.

Key management and environment variables

Always inject keys through environment variables or a secrets manager — never hard-code them, never commit them to a repository, never paste them into a ticket. Below is an example for local debugging; the address and key in it are placeholders and must not be used in production:

# Local debugging: reach the API endpoint through the local proxy provided by the client on this machine
# All example values are placeholders — replace them with your own configuration
export HTTPS_PROXY=http://127.0.0.1:7890
export HTTP_PROXY=http://127.0.0.1:7890
export NO_PROXY=localhost,127.0.0.1,.internal

curl -sS https://api.example.com/v1/models \
  -H "Authorization: Bearer sk-xxxx"

Note the NO_PROXY line: excluding loopback addresses and internal domains keeps local services out of the route and removes an unnecessary point of failure. The same rule applies in containers and remote development environments.

Handling streaming responses

An API streaming response is a data stream that arrives over time; the client should process it incrementally as it arrives rather than waiting for the end before parsing. Two things matter in the implementation: set the read timeout longer than a single generation takes, and log interruptions properly — after an interruption, don't blindly rerun from the start; first check whether the part already generated is usable. Building these two things into your code beats debugging the network afterwards.

07Developer Setups: CLI, IDE Plugins and CI

What makes a development environment special is that it's made of many small independent tools, each with its own way of setting a proxy. Miss one and you get the classic pattern where some commands run fine and others time out. This chapter groups them by tool type.

Proxy inheritance in CLI tools

Most CLI tools read the HTTPS_PROXY and HTTP_PROXY environment variables. Put them in your shell config file and every new terminal inherits them. For one-off use, prefix a single command with the variables and they disappear when the terminal closes. Note that support for upper- and lower-case names varies between tools — when in doubt, set both.

Package managers and version control

Package managers and version control tools often have their own settings and don't read environment variables. Typical commands look like this — replace the address with your local proxy port:

# Version control: go through the local proxy on this machine
git config --global http.proxy http://127.0.0.1:7890
git config --global https.proxy http://127.0.0.1:7890

# Package manager: point at the same local proxy
npm config set proxy http://127.0.0.1:7890
npm config set https-proxy http://127.0.0.1:7890

# Clear the values above to go back to a direct connection
git config --global --unset http.proxy
git config --global --unset https.proxy

It's important to note down the commands that restore a direct connection too: on a corporate network or when working with local repositories, leftover proxy settings slow down or break commands that used to work.

IDE plugins and built-in editor models

Completion plugins in editors usually have their own proxy setting and don't read system environment variables. Look for the plugin's own network settings first and enter the local proxy address there; if the plugin has no such setting, then consider letting the editor process inherit the system proxy. Completion requests are frequent and small, sensitive to both latency and packet loss, so pick a route with steady latency rather than chasing peak bandwidth.

CI and headless environments

CI environments have no interactive UI, so everything has to be configured through environment variables and secret management. Three principles: keep the exit fixed — don't switch regions randomly within one pipeline; inject keys through the pipeline's secret management, never into repository files; and make failures log clearly, so you can tell a network failure from an API failure.

# Inject in the pipeline; never commit to the repository
export HTTPS_PROXY="$CI_PROXY_URL"
export API_TOKEN="$CI_API_TOKEN"

# Retry only idempotent steps, and only a limited number of times
for i in 1 2 3; do
  run_task && break
  sleep $((i * 5))
done

Containers and remote development

Networking inside a container is isolated from the host, so 127.0.0.1 in a container points at the container itself, not the host. To route a container through the host's local proxy, use an address that reaches the host on the container network and pass the environment variables explicitly at startup. Remote development environments are the same: first confirm the proxy address is reachable from that environment, then talk about configuration.

08Rate Limits and Account Flags: Causes and Prevention

Rate limiting and account flags are two different things, but they often show up together. Rate limiting is short-lived and recoverable; an account flag is a state, and slower to clear. Telling them apart tells you whether to wait or to change your setup.

Shared exits and guilt by association

When one block of exit addresses is shared by a large number of users, the service sees the combined behaviour of the whole block. Someone else's abnormal activity is spread across the block, and your own usage can be downgraded along with it no matter how clean it is. The signature of this problem: symptoms come and go and don't track anything you do locally. The way around it is to choose routes that are stable over the long term with a fairly settled user base, rather than constantly changing address blocks.

Jumping between regions in a short window

Switching from one continent's exit to another and back again is the most easily flagged pattern. If you genuinely need multi-region access, group it by task: stay in one region for a stretch, then switch everything over, instead of hopping back and forth within minutes.

Request rates and automation scripts

Scripts fire requests at a rhythm no human matches, and it's easy to produce high-frequency bursts. Three things to watch: add intervals to batch jobs; cap retries and add backoff; and don't run several high-concurrency scripts through the same exit at once. MeyeVPN doesn't limit how many devices are online at the same time, but that doesn't mean concurrency can be stacked without limit — with the same exit address, the rates are counted together.

Where multiple accounts cross the line

Running several accounts through the same exit address is a high-risk practice. If you have a legitimate need for multiple accounts — different roles in team collaboration, say — spread them across different exit regions and keep each account's usage pattern fairly consistent. Avoid several accounts acting the same way, at the same moment, from the same address.

Prevention checklist

1. Pick a regular region and don't make unnecessary cross-continent jumps.
2. Serialise batch jobs and control the rate at the queue layer.
3. Retry with backoff, and cap the number of attempts.
4. Don't stack multiple high-concurrency streams on one exit.
5. Keep account details consistent — avoid contradictions between sign-up, billing and usage regions.
6. When you hit a rate limit, slow down and wait rather than switching routes immediately — a new route means a new exit address, which adds a second risk signal on top.

09Choosing Routes, Matching Plans and a Troubleshooting Checklist

The final chapter turns the conclusions of the previous eight into choices you can act on. There's no 'best' route or plan — only the one that matches how you use it.

How to choose between the three route types

Routes on this site fall into three types by how they connect, each suited to different situations. The table lists common regions and types; see the nodes page for the full list.

The recommended order: filter by the region the target service requires first, then sort within that region by route type — for long-lived AI work, dedicated lines come first; use a direct-connection route only when you want to check quickly whether a region works.

Matching plans to usage

Monthly subscriptions come in three tiers: ¥9.9/month for 60GB, ¥18/month for 250GB and ¥28/month for 500GB. Data resets every month on your activation date, and if you upgrade mid-cycle the difference is prorated across the remaining days. For light use — a few conversations a day and the occasional lookup — the 60GB tier is plenty; if AI tools are part of your daily workflow, 250GB is more comfortable; and if you run long batch jobs, consider the 500GB tier.

If your usage swings a lot and you'd rather not renew monthly, look at data packs: ¥158/300GB, ¥358/1000GB and ¥658/3000GB — use them until they run out, and they never expire. Data packs suit uneven usage such as business trips or concentrated projects. Every tier allows unlimited simultaneous devices, supports Windows / macOS / iOS / Android / Linux, takes Alipay / WeChat / USDT, and comes with a 30-day no-questions-asked refund — run your real workload on one tier first, then decide whether to upgrade. That order is safer than buying the top tier outright.

Troubleshooting checklist

Work through these in order, reproducing the issue after each step and noting whether the symptom changes:

1. Confirm your exit region: does it match what the target service requires? If not, change region first and leave everything else alone.
2. Clear stale web state: reload after switching routes; if that doesn't help, clear the site's cookies and local storage, or check in a private window.
3. Put split routing back on rule mode: rule out the extra traffic and request rate that global mode brings.
4. Try another route in the same region: if the symptom disappears it's a path problem; if it stays the same, the route isn't involved.
5. Reproduce on a different route type: direct connection to dedicated line, or the other way round. This step separates a speed problem from a stability problem.
6. Check your local environment: leftover proxy settings, whether a container can reach the host proxy, whether power saving has killed the client process.
7. Lower your request rate: cut concurrency and retries, wait a few minutes and try again, to tell a rate limit from an account flag.
8. Record the full symptom: when it happened, which route you were on, the exact message you saw, and whether it reproduces. Bringing those four things when you ask for help makes the conversation far more efficient.

When you need a hand

The support ticket form is inside the user panel — log in to submit one. Please include the four details from item 8 above. If the problem is that you can't tell whether it's a region issue or a path issue, go back to the tip block in Chapter 02 and triage with it first; that usually points you to the right chapter on its own.
