Every error body is { error, code, request_id, ... }. All codes and what to do.

401: Missing, wrong, revoked or expired API key (code UNAUTHORIZED, KEY_REVOKED, KEY_EXPIRED).
403: The key may not do this (SCOPE_DENIED, MODEL_NOT_ALLOWED, TEST_MODE_UNSUPPORTED, ACCOUNT_BLOCKED, allowance_exceeded).
404: No such id, or it is not yours, or it belongs to the other key mode (NOT_FOUND).
409: IDEMPOTENCY_CONFLICT or CALLBACK_NOT_RETRYABLE.
422: The request is not valid (VALIDATION_FAILED, INVALID_JSON, PREFLIGHT_FAILED, CALLBACK_URL_INVALID, REFERENCE_*). `issues` lists each problem. Nothing was charged.
429: Too many requests or jobs (RATE_LIMITED, CONCURRENCY_LIMIT, UPLOAD_QUOTA, …). Wait Retry-After seconds, then retry.
500: Our fault (INTERNAL_ERROR). Quote request_id to support.
503: Paused or busy (API_PAUSED, MODEL_PAUSED, PROVIDER_PAUSED, PROVIDER_BUSY, UNAVAILABLE). Wait Retry-After seconds, then retry.
