Infrastructure layer

A verdict API with an evidence spine.

Gatekeeper is simple by design: one decision endpoint, one evidence trail, one proof portal. Your product remains sovereign.

Workflow

Client integrates Login Gate.
Payment webhook updates payment state.
Lock-state API returns verdict.
Client app blocks or allows.
Evidence stored automatically.
Portal shows proof.

Modes

OBSERVE: produces proof, does not block.
ENFORCE: denies when unpaid beyond threshold; allows after verified payment.
