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 18 rate-limit definitions, measuring requests_per_second and requests_per_minute.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled.

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

Policies

Enterprise Exemption
Enterprise plans have no endpoint-specific overrides; the global limits apply.
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.
