  update:
    x-response-envelope:
      description: 'Every response carries success (boolean) and message (string|null) alongside the payload.
        success describes the API call, NOT the verification verdict: an undeliverable address still returns
        success: true.'
      fields:
      - success
      - message

  update:
    x-rate-limits:
      parallel_per_ip: 25
      requests_per_clock_minute: 8000
      status_on_exhaustion: 429
      response_headers: []
      note: No RateLimit-*, X-RateLimit-* or Retry-After headers are returned; limits must be enforced
        client-side.

  update:
    x-idempotency:
      supported: false
      note: No idempotency key documented. GET operations are naturally retry-safe; PUT /v2/verify-batch
        is not — a retry creates a second job and consumes credits again.

    description: Open disposable-domain lookup. This is the host in Kickbox's own published OpenAPI (openapi/kickbox-disposable-openapi.json);
      the first-party SDKs use open.kickbox.io, which also answers.
