Engine answers from in-memory hash map — zero DB readsLatency shown is the engine's own nanosecond timer, not network RTT

Built for Production

Every component is optimised for the workloads that break typical BIN lookup services.

In-Memory Engine

Pure Go hash-map lookup with zero DB hops. 5 million BINs loaded at startup, O(1) access every time.

Key-Level Auth

ULID-indexed API keys synced to the Go engine every 30 s. Revoke a key — it stops working within the next sync cycle.

Real-Time Billing

Usage counters aggregated every minute. Subscription, Pay-as-you-go, and overage all tracked with $0.005 precision.

Country & BIN Data

Issuer country, card brand, card type, and result code returned on every lookup. Built for fraud prevention pipelines.

REST API

Clean versioned JSON API. Bearer token auth, structured error codes, no SDKs required — works with any HTTP client.

Hot Reload

valid_keys.json is reloaded atomically every 30 s using lock-free atomic.Pointer. Zero downtime on key changes.
