Most Task, Analytics, and Billing JSON endpoints return errors in the standard envelope described on API reference overview. This page collects exceptions and practical handling so you do not have to infer behavior from status codes alone.Documentation Index

Standard JSON error envelope
error.code values include BAD_REQUEST, UNAUTHORIZED, FORBIDDEN, NOT_FOUND, TOO_MANY_REQUESTS, NOT_IMPLEMENTED, and INTERNAL_SERVER_ERROR. Your client should branch on HTTP status and error.code, not only on message text.
401 vs 403
| HTTP | Typical error.code | Meaning |
|---|---|---|
| 401 | UNAUTHORIZED | Missing or invalid credentials (no user identity). |
| 403 | FORBIDDEN | Identity is present but the token lacks scopes for the route. |
Authorization: Bearer … or X-API-Key usage when the deployment expects a specific header.
Rate limiting (429)
Control-plane throttling and preview quotas use different bodies and headers. Read Rate limits for RPM defaults,X-RateLimit-* headers, preview preview_limit_exceeded shapes, and backoff guidance (there is typically no Retry-After on control-plane 429).
Feature flags and disabled routes
Some routes return 404NOT_FOUND when a capability is turned off in your environment (for example execution-plan steps when the plan feature is disabled). The OpenAPI operation description in the API Reference tab usually states the exact message—search the operation you are calling.
Responses without the success envelope
| Surface | Success | Errors |
|---|---|---|
GET /api/v1/executions/:id/results/export and …/results/download | Raw file bytes (Content-Disposition: attachment) | JSON error envelope when the handler rejects the request |
Media CDN GET /media/...?token=… | Binary stream | { "error": "<message>" } without a success field |
| Some billing operations | Varies by deployment | May use legacy { "error": "..." } shapes; see the Billing API operation text |
