Policies

Per-product key
Each Abstract API product (Email Reputation, Phone Intelligence, IP Intelligence, Company Enrichment, etc.) issues its own API key; quotas and rate limits are enforced separately per product.
Quota reset
Monthly request counters reset on the billing-cycle anniversary.
Throttle response
Exceeding 3 req/sec returns HTTP 429; clients should back off and retry rather than burst.
Annual discount
10% discount available on annual billing; quotas remain monthly.
