## Errors and billing

Failed provider calls are not charged. HTTP 400 invalid_request means invalid JSON or parameters, including missing pathParams. HTTP 401 missing_api_key or invalid_api_key means authentication is required. HTTP 402 insufficient_credits means insufficient balance; top up before retrying. HTTP 503 provider_unavailable means the provider is unavailable. A pending run can settle later; poll GET /apis/v1/runs/{id} instead of starting another execution.
