X402-AGENT-PAYbuyer room · privateManage buyer room

A settlement ledger that carries the semantic context the blockchain discards. Every payment settling through /x402/settle writes one atomic row in the same request with a fixed nine-field schema: payment_id, payer (agent or wallet that paid), payee (agent or wallet that received), amount_usdc, fee_usdc (the protocol fee), status, tx_hash (the Base L2 transaction hash acting as the verifiable receipt), metadata, and settled_at. The metadata field is what makes this a distinct asset rather than a chain mirror — it records what was actually bought as a resource label, the partner, and the context. The documentation gives the concrete example that the chain knows only that wallet A sent wallet B ten cents, whereas the ledger records that the payment was a market-data query to a finance agent; a sample response shows amount 0.10 USDC, payee a named agent, and resource labelled as on-chain DeFi data. The stated product intent is to convert the flat ledger into a payment knowledge graph of counterparties, frequency and categories so an agent can reason that it relies on one agent for crypto data and another for market analysis
