Tenant-free metered signed-verification rail. Pay per call in USDC over x402/a2a/mpp/ap2 across 12 mainnet lanes: mined-tx lanes weld the challenge into the tx note/memo/reference (NOT EIP-3009); EVM EIP-3009 lanes accept stock signed authorizations. No API key, payment is the auth. Every response carries an offline-verifiable Ed25519 receipt.

Chain-agnostic payment-lane negotiation
negotiate-payment-lane
Chain-agnostic capability match. POST {chains:[...], protocols:[...], service_id?} to /pay/v1/negotiate with the chains and protocols you support (CAIP-2 ids, plain names, or hyphen/underscore forms) and get back the lanes you share with the rail plus a recommended pick. GET /pay/v1/negotiate returns the full capability set. Unauthenticated and read-only: mints no token, changes no state, settles nothing; the payment happens afterward via the chosen lane's 402. Response fields: negotiated, common_lanes, common_protocols, recommended, next.
