default The request failed. The body carries the standard error envelope: a machine-readable `error.code`, a human-readable `error.message`, and `error.validationErrors` when the failure was a validation rejection. See the error-code reference in this document's description for the values `error.code` can take.

429 The request was refused because a rate limit was exceeded. Wait at least the interval `Retry-After` names before retrying, then back off. Limits are tuned per deployment, so read the allowance from the response headers rather than assuming a fixed ceiling.

Body: RateLimitProblemDetails Each item has these fields.

Field Type Description
type required string The problem type identifier. Always the same value: the failure is the status code itself, so there is no sub-type for a caller to branch on. nullable
title required string A short, human-readable summary of the problem type. nullable
status required integer (int32) The HTTP status code, repeated in the body as the problem-details format defines.
detail required string A human-readable explanation of this occurrence of the problem. nullable
retryAfterSeconds required integer (int32) How long to wait before retrying, in whole seconds, carrying the same figure as the `Retry-After` header. Always at least one: a value of zero would invite an immediate retry that is certain to be rejected again.

This response has no documented body fields.
