Emailrep Rate Limits

EmailRep enforces rate limits per API key. The Free (Community) tier is capped at 250 queries per month with a 10-queries-per-day daily ceiling. The Commercial tier raises the monthly quota to 1,000 and removes the daily cap. Enterprise plans negotiate high-volume quotas with SLAs. Anonymous (no API key) queries are heavily rate-limited per IP and are intended for ad-hoc lookups via the emailrep.io web UI. Rate-limit enforcement returns 429 Too Many Requests; submit reports and reputation queries should back off and retry with exponential delay when throttled.

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

Policies

API Key Required For Reports
The POST /report endpoint requires an API key. Anonymous report submission is not supported.
Tier-Based Scoping
Rate limits are bound to the API key. Each key carries one of the Free, Commercial, or Enterprise quotas.
429 Retry With Backoff
When a quota or per-day ceiling is exceeded the API returns 429. Callers should back off with exponential delay and retry on the next window (next day for Free, next month for paid).
Raise Via Support
Commercial and Enterprise quotas can be raised by contacting Sublime Security through the contact form at sublimesecurity.com/contact.
Web UI Lookups
The emailrep.io web UI provides ad-hoc lookups for security analysts without an API key, subject to per-IP throttling.
