DEVELOPER DOCUMENTATION

Every credit has a boundary.

Standard lookups cost one account credit; comparisons cost two. Free accounts receive a hard cap of 1,000 credits per UTC calendar month. Paid periods follow verified subscription billing periods. Cache hits at the API still count; SDK cache hits avoid a new call.

Separate website allowance

Anonymous visitors get ten chargeable actions per UTC day. A signed first-party visitor cookie and rotating server-side HMAC identify continuity without canvas/audio/font fingerprinting. Network-prefix and visitor burst counters supplement it; this is best-effort abuse resistance, not a claim of perfect identity.

Quota is conditionally reserved in a database transaction before lookup. Audit and credit changes commit together. Invalid inputs and unavailable sources do not use daily allowance; no-match results do. Failed abuse checks are still audited and burst-limited.
