401 or invalid API key
Check whether the key belongs to the right project, is copied fully, is stored server-side, and is sent with the Bearer prefix.

API troubleshooting
Troubleshoot OpenAI-compatible API errors before changing providers
Most API failures can be narrowed down quickly if you check the base URL, API key, model name, quota, request logs, and live pricing in the right order.
Common causes
429 or rate limit
Reduce concurrency, retry with backoff, check project quota, and inspect whether the same key is shared by multiple tools.
Model not found
Confirm the model exists on live pricing, the model name is exact, and the endpoint type matches your request shape.
Base URL mismatch
Use https://api.tacklekey.com/v1 for OpenAI-compatible requests unless your console or docs show a project-specific endpoint.
Debugging order
| Step | What to check | Entry |
|---|---|---|
| First raw request | Run the cURL example first so SDK wrappers are not hiding the real status code. | Open |
| Logs | Find the request by project key, model, timestamp, status, and error message. | Open |
| Balance and pricing | Check whether the request consumed quota and whether the model price matches expectations. | Open |
| Small retry | Retry with one short prompt after fixing the most likely configuration issue. | Open |
Do not rotate keys or switch providers blindly. First capture one small failing request, then compare the status code, request body, logs, and billing record.
FAQ
Why does an OpenAI-compatible request return 401?
Common causes include a missing Bearer prefix, using a key from another project, copying whitespace, using a revoked key, or sending the request to the wrong base URL.
How should I handle 429 rate limits?
Use exponential backoff, lower concurrency, avoid sharing one key across many jobs, and check project quota and logs before increasing traffic.
What should I do when a model name fails?
Copy the model name from live pricing or docs, confirm endpoint support, and send one small request before using the model in a batch.
