Enrich · Rate Limits

Enrich So Rate Limits

Enrich enforces global per-account rate limits that scale with your plan, expressed as a burst limit (requests per second) and a sustained limit (requests per minute averaged over a 60 second window). Enrichment and bulk endpoints carry tighter per-endpoint overrides than the global limit. Every response returns X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset headers; exceeding a limit returns HTTP 429 with a Retry-After header. The tier values below are captured from the Enrich rate-limits documentation and should be reconciled against the live docs, which control.

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

It captures 12 rate-limit definitions, measuring requests_per_second and requests_per_minute.

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

Tagged areas include Data Enrichment, Contact Discovery, Web Intelligence, Rate Limiting, and Quotas.

Enrichment Endpoint Override endpoint
requests_per_minute
stricter than global
Enrichment endpoints (person/company/phone) have tighter per-endpoint caps than the global sustained limit.
Bulk Submission Override endpoint
requests_per_second
stricter than global
Bulk/batch submission endpoints are throttled below the global burst limit (Free plan ~1 rps).

Policies

Tiered Limits
Burst and sustained limits increase from Free through Growth, Scale, Pro, and Enterprise plans.
Backoff Strategy
On 429, honor the Retry-After header and implement exponential backoff with jitter.
Rate Limit Headers
Read X-RateLimit-Remaining and X-RateLimit-Reset to pace client throughput proactively.
