Pay only when the answer is correct

Trust, resolved in public.

Verity holds x402 settlement until an AI response passes a deterministic check. Wrong answers are refused, disputes are replayable, and both sides earn portable reputation.

402 challenge→deliver→verify→settle or dispute→HCS receipt
Delivery firstThe buyer evaluates the real response before value moves.
Mechanically correctPublished rules—not model opinion—decide settlement.
Replay anywhereMirror Node and content hashes reproduce every verdict.

Two-line integration

Keep your API. Add a verdict.

One wrapper protects an existing x402 handler. The provider chooses a published rule; Verity handles the challenge, delivery-first flow, and evidence.
