Persona · Rate Limits

Withpersona Rate Limits

The Persona API enforces a default per-environment rate limiter of 300 requests per minute across all API keys in an environment, plus product-specific quotas that cap object creation - for example, Inquiry Created requests are limited to 150 per minute. The count starts on the first request in a 60-second window and resets at the start of the next minute. Requests over the limit return HTTP 429 Too Many Requests, and responses expose the limit, remaining requests, and reset seconds as headers.

Withpersona Rate Limits is the machine-readable rate-limit profile for Persona on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 3 rate-limit definitions, measuring requests.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Identity, Identity Verification, KYC, KYB, and AML.

Policies

Rate Limit Headers
Responses return the API limit, remaining requests, and seconds until reset as response headers.
Idempotency Ordering
The rate limiter executes before the idempotency layer, so a 429 is not deduplicated by the Idempotency-Key header.
Backoff Strategy
Clients should implement exponential backoff with jitter and honor the reset window before retrying.
