Baiyun API Tutorial: Common Errors and 429
Methods for troubleshooting error codes, authentication, rate limiting, temporary blocks, interfaces, and fee issues. Includes complete inspection steps, practical verification, and error handling.
Common errors with 429
When encountering errors, first check the HTTP status and the returned version error.message、error.code and request number. The same status code may come from different stages, and the root cause cannot be confirmed by numbers alone.
Common state
| Status | Possible reasons | Suggestion |
|---|---|---|
| 400 | Request fields, formats, or functions are not available | Refer to the text examples on this site and delete the tools, files, and media fields automatically added by the client |
| 401 | Keys are missing, invalid, or incorrect | Check the Bearer format and the site key; you don't need a web login password to call the model |
| 403 | Permissions, usage rule refusals, or temporary suspension of credentials | Read the specific instructions and stop repeatedly submitting prohibited content; Temporary lockdowns await restoration |
| 413 | Asking for too much | Shorten conversation history and text; the current request body limit is 1 MiB |
| 429 | Concurrency, frequency, or upstream limits | Wait for now, judge based on the specific error content, and do not try indefinitely |
| 500 / 502 / 503 | Services or upstream services are temporarily unavailable, and complete responses have not been obtained | Keep the request number and time, with limited retries later |
Business errors such as insufficient balance, unavailable models, or unconfigured pricing should also be read and returned to the main text; you can't just look at status codes or frontend pop-ups.
429 It's Not Necessarily That You "Ask Too Much"
429 indicates that a certain layer restricts the request. Currently, each credential can be processed at most simultaneously 2 requests, the model call frequency limit is 60 beats per minute； Upstream also has its own resource and usage limits.
concurrency_limit: Wait for the existing request to be completed before sending the next one. Stream requests still occupy concurrency until they end.- Regular frequency limit or upstream 429: respect
Retry-After(If available), use a limited number of retries with gradually extended waiting periods to avoid immediate repeated requests. - Page directly shows HTTP ERROR 429: Browser page requests may also be restricted; Wait a moment before refreshing; if it continues, keep the occurrence time and path for the administrator.
If a normal text issue is misjudged, the request number and necessary non-sensitive notes can be provided for review; Do not send available keys, passwords, or full sensitive original texts.
403 Temporary sealing with vouchers
content_policy_violation This indicates that this request has met the site's usage restrictions and was rejected before sending to upstream.
credential_temporarily_blocked Return 403, and provide Retry-After Wait prompt: After the same credential hits the rule multiple times within 30 minutes, pause for 30 minutes. Please stop the related content and wait for recovery; do not continue trying by changing the key. This is different from 429 concurrency or frequency limitation.
Interface address and model issues
The base URL should be https://api.baiyun.si/v1, the full Chat address is /v1/chat/completions, Responses address: /v1/responses。 Check for duplicates /v1/v1, and whether the client has selected protocols not open to this site.
The model name must be associated withModel Squareand the current key /v1/models Return consistently; do not use client-side display aliases to replace the actual call name.
Streaming and cost issues
Chat SSE should read [DONE]； Responses SSE should read the full end of the event. Some text after network disconnection cannot be considered a complete successful response.
Input and output parameters do not guarantee a hard cost cap. Normal requests, failures after entering upstream, or client cancellations must be verified against actual consumption records; Only requests rejected locally and without going upstream will not be charged for this model call.
What is provided during the inspection?
- Time and time zone.
- Request number, model name, interface path, and HTTP status.
- Error messages after removing keys and sensitive content.
- For payment questions, provide the order number and status, but do not provide the payment merchant key.
The station is still gradually improving and has not yet committed to round-the-clock manual response or fixed processing time limits.
Checklist before practical use
- Prepare your own account and access keys, and do not use others' shared credentials.
- Records client versions, systems, and models to be used for easy reproduction during troubleshooting.
- Save the original configuration or screenshot, hide keys, verification codes, and private content.
- Confirm that testing may consume a small amount of DK, starting with a single sentence and a single request.
- Review the current model plaza and status page before deciding whether to enable more features.
Detailed investigation: narrow down the scope of the problem in order
First, confirm that the account is complete, the key is valid, and the DK balance is sufficient, then verify the protocol, address, and model. Make a minimum text request using the same key; Only after it succeeds does it restore attachments, tools, or automatically retry each item. After saving the client configuration, reopen the session to avoid using the previous vendor in the old session.
How to confirm that this section has been learned
Don't just check the "Configuration saved successfully" prompt. You should be able to clearly state the current Base URL, key usage, chosen model, and request protocol, and be able to verify your operation results on the corresponding console. The client-side tutorial uses a single actual plain text response and corresponding logs as the initial completion standard; Account tutorials are based on comprehensive security information; The billing tutorial uses the correspondence between principal, channel fees, and DK as the standard.
If an error occurs, record the occurrence time, HTTP status, content of the anonymized error, and the actual expected result. Do not screenshot the entire page key, and do not give the password or verification code to others. For 401, authentication should be resolved first; for 400, parameters should be resolved first; for 429, intensive retries should be stopped; for 404, request paths and upstream verification should be verified; recharging cannot resolve all errors.
A small task suitable for practice
Complete the minimum steps in this section in your own testing environment, recording in text "how you originally set it, which item you modified, and what results you saw." Do not treat production data, real payments, or irrecoverable commands as exercises. If you encounter features beyond what this section offers, first check the corresponding protocol tutorial before considering adding features; Changing only one configuration at a time makes it easy to judge which step leads to errors.
The next step is the boundary of the version

The tutorial was compiled on October 9, 2026. The specific interface and capabilities may vary depending on the client and upstream versions; The configuration guidelines do not mean that all client versions have passed the test. For balance payments, QQ / Alipay login, and open channels, please refer to the actual page page; Compression interfaces: Previously, upstream 404 and raw image channels were not available, so don't assume configuration files can be automatically removed.
