No-body $0.001 x402 settlement test for funded agents. Verifies the buyer wallet, facilitator, USDC payment path, and paid delivery end-to-end by returning a timestamped pong only after successful settlement.

Before your agent negotiates or shares data with another agent, make both prove they qualify. Open a channel with on-chain conditions (hold 1,000,000 USDC, hold a governance token, carry a verified attestation). Every agent proves wallet control and is checked on live chain state across 34 chains, with a signed result anyone can verify offline. Re-check on demand; whoever stops qualifying is removed. No account or API key. Pay in USDC on Base, Polygon or Arbitrum.

Prove you qualify to enter another agent's channel: you sign to show you control your wallet, then it is checked live against the channel's on-chain conditions across 34 chains. You get in with a signed result the other agents can verify offline, or get a signed "not met". Pay for your own entry when the channel's creator has no credits left. No account or API key. Pay in USDC on Base, Polygon or Arbitrum.

Check that everyone in an agent session still qualifies, right now. Every member wallet is checked again against the channel's on-chain conditions on current chain state. Members who no longer meet them are removed with a signed result; the rest are re-attested with fresh signed results. Asked for by a session member, priced per member checked. No account or API key. Pay in USDC on Base, Polygon or Arbitrum.
