Errors
Interpret failures without duplicating work or increasing spend.
Read as Markdown ↗Error envelope
Most API failures use the following shape. Some errors omit code; inspect the HTTP status and safe message as well.
{
"error": {
"code": "PRICE_CHANGED",
"message": "The current price exceeds your requested Gem limit."
}
}| HTTP | Code | What to do |
|---|---|---|
| 401 | INVALID_API_KEY | Check secret format, expiration, and revocation. |
| 403 | INSUFFICIENT_SCOPE | Use a key with the required scope. |
| 403 | ACCOUNT_BLOCKED / ACCOUNT_UNAVAILABLE | Resolve account access or finish account setup. |
| 402 | API_KEY_LIMIT | Check cap and outstanding reservations; do not raise the cap automatically. |
| 402 | LLM_QUOTA_EXHAUSTED | Check the account's LLM allowance and paid-Gem settings. |
| 409 | PRICE_CHANGED | Reduce request cost or obtain approval for a higher ceiling. |
| 409 | IDEMPOTENCY_CONFLICT | Restore the original body for this identity; use a new identity only for a distinct authorized request. |
| 409 | REQUEST_UNCERTAIN | Keep the original key, body, and identity. Check/replay with backoff; never blindly dispatch a new request. |
| 409 | REQUEST_FAILED | The original claim was released. A new authorized generation needs a new identity. |
| 409 | REFERENCES_PROCESSING | Keep the same identity and check reference readiness. |
| 409 | ANALYSIS_FAILED | Analysis could not be parsed; measured usage may already be billed. |
| 404 | NOT_FOUND | Check the route/task ID and ownership. |
| 413 | optional INVALID_REQUEST | Reduce payload size. |
| 422 | INVALID_REQUEST / INVALID_REFERENCE / MODEL_UNAVAILABLE | Check fields, references, and discovered models. |
| 503 | WORKFLOW_UNAVAILABLE / PROVIDER_UNAVAILABLE / TEMPORARILY_UNAVAILABLE | Preserve the original request identity and apply backoff. |
Other canonical generation/policy errors can be returned. Do not bypass account restrictions or moderation by rewriting requests or switching keys. Provider failures can leave uncertain reservations; a 5xx is not permission to resubmit with a new identity.
For support, retain safe IDs, status, code, and timestamps. Exclude bearer keys and signed media URLs from logs. For SSE, inspect in-stream errors and require [DONE] before reporting a complete text result.
