        DataForSEO and differs from the account password. Credentials cannot be

    update:
      x-error-semantics:
        note: >-
          This API returns HTTP 200 for nearly every outcome. The authoritative
          result is the numeric status_code / status_message pair, present both
          at the top level of the response envelope and inside each element of
          tasks[]. Branch on status_code, not on HTTP status.
        http_codes_used: [200, 401, 402, 404, 500]
        code_range: 10000-60000
        catalog: errors/dataforseo-problem-types.yml
      x-rate-limit-semantics:
        limit: 2000 requests per minute per account
        exhaustion_status_code: 40202
        concurrency_status_code: 40209
        headers: none
      x-idempotency:
        supported: false
        note: >-
          No idempotency key is documented. Record the task id before POSTing and
          poll tasks_ready / id_list before retrying — retries are billable.
