X402-agent-pay

AgentPay (x402-agent-pay.com) — 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 l…

X402-agent-pay offers (Alternative, Reference, Sentiment) — Row count likely modest — settlement volume appears small by the site's own illustrative figures — but the per-row label is uniquely valuable. Each settlement contributes a resource-category label plus an agent-to-agent edge, so the derived graph is more informative than the row count suggests. Two components would be genuinely hard to replicate: the historical resource labelling, which cannot be backfilled onto chain data retroactively, and the agent identity resolution that lets payer and payee be named agents rather than anonymous addresses.

Training agents to choose which service agents to buy from using observed dependency and pricing patterns — the knowledge graph is directly consumable as a preference or ranking signal; building the machine-economy service-dependency graph, which has no other source since the chain itself is relationship-free; category-level demand measurement for what agents actually purchase (data feeds, compute, analysis) rather than what humans claim they will buy; agent cost-optimisation and substitution models from observed amounts per resource category; protocol fee and take-rate benchmarking for x402 infrastructure; and verification workflows, since every record is independently checkable against Base
