UNAUTHENTICATED — missing or expired token.Show more
UNAUTHENTICATED — missing or expired token. Declared on every operation because `security` is declared globally at the document root: every route is authenticated, so every route can answer 401. - 403ApiErrorResponse

AGENT_TIER_INSUFFICIENT, also 403, is a request whose agent tier does not allow the tool class; it carries nextAction verify_agent and details.tier, details.required, details.toolClass and details.operationId. A ceiling only narrows an unverified caller and never widens a scope. - 405ApiErrorResponse

VALIDATION — the request body is larger than the surface's limit.Show more
VALIDATION — the request body is larger than the surface's limit. Not retryable as sent: shrink the body. Declared on every operation that takes a request body. details carries exactly one key, maxBodyBytes (integer): the limit that applies to this surface, in bytes. - 414ApiErrorResponse

VALIDATION — the request URI (path and query string) is longer than 8 KiB; the public edge refuses it before the platform sees it (details.reason URI_TOO_LONG, details.source edge). Not retryable as sent: send long input in the body of a POST. - 415ApiErrorResponse

VALIDATION — a request body that is not JSON (application/json or application/*+json; a form body only on the OAuth token routes). The public edge refuses it before the platform sees it (details.reason UNSUPPORTED_MEDIA_TYPE, details.source edge). Not retryable as sent: send Content-Type application/json. Declared on every operation that takes a JSON request body. - 429ApiErrorResponse
RATE_LIMITED — the API key or its tenant is over a rate limit; wait for Retry-After, then retry.Show more
RATE_LIMITED — the API key or its tenant is over a rate limit; wait for Retry-After, then retry. Every routed request is counted against two token buckets, the key's and the tenant's (all its keys together): 50 requests a second with a burst of 100 on the standard plan. Every travel verb except polling a search also spends from a supplier budget, per key and per tenant: 10 requests a second with a burst of 20, and a plan may add a daily quota of supplier calls. Answers carry the IETF RateLimit header fields for the tightest bucket consulted (RateLimit-Limit, RateLimit-Remaining, RateLimit-Reset, RateLimit-Policy); a refusal adds Retry-After and details.scope (KEY or TENANT), details.budget (PLATFORM or SUPPLIER), details.reason (RATE or DAILY_QUOTA), details.tier and details.retryAfterMs. A sandbox may run with the limiter off, in which case none of these headers is sent. A search that is still warming is a different answer with a different meaning (keep polling). with the key-velocity check on, also details.reason VELOCITY_LIMIT, a soft breach of the API key's own scope (components/responses/VelocityLimited), nextAction slow_down. - 500INTERNAL — a bug, and traceId is the support handle.ApiErrorResponse
