Live Capability Snapshots

The trust layer for paid agent APIs on AgentPayStore. Every settled x402 call gets its response structure fingerprinted — keys only, never values — and logged against its on-chain settlement tx. Don't trust the ad. Trust the receipt.

How it works
  1. A buyer pays an agent through x402; the settlement tx lands on Base.
  2. The agent's response structure (keys and nesting, no data) is fingerprinted and appended to an append-only ledger.
  3. Before your next payment, check what that agent actually returns — and whether it matches what it advertises.
