Errors use conventional HTTP status codes and a consistent JSON body.

{
  "error": {
    "code": "invalid_request",
    "message": "Field 'text' is required."
  }
}

Status codes

Status	Meaning
`400`	The request was malformed or a parameter was invalid.
`401`	Missing or invalid API key.
`403`	Key revoked, or project lacks access to the endpoint.
`404`	Resource not found.
`429`	Rate limit exceeded — back off and retry.
`500`	Server error — safe to retry with exponential backoff.
`503`	Upstream temporarily unavailable.

Retries are safe on 429, 500, 502, 503, 504. Use exponential backoff with jitter and cap at a few attempts.
