Debounce Rate Limits
DeBounce applies CONCURRENCY limits rather than per-minute or per-day request quotas for private API keys, and a hard per-IP daily cap for public browser keys. The limits are documented clearly — but they are not signalled at runtime: a live probe of the API on 2026-08-14 returned no RateLimit-*, X-RateLimit-* or Retry-After header on any response, so a client discovers the ceiling only by receiving a 429 and must choose its own backoff.
Debounce Rate Limits is the machine-readable rate-limit profile for DeBounce on the APIs.io network, conforming to the API Commons Rate Limits specification.
It captures 4 rate-limit definitions.
Tagged areas include Email Validation, Email Verification, Deliverability, Disposable Email Detection, and MX Records.
