The x402 census · for agents choosing who to pay, and the platforms that list them
The open observatory for verified agentic-commerce settlement & trust.
Who is really getting paid over x402 (the open HTTP-402 payment protocol for agents and APIs) — and do they deliver? Every figure here is observed by us: indexed on-chain settlement (Base, Solana, Algorand and more), our own liveness probes, and paid delivery tests. Sellers’ self-declared claims are labelled, never counted.
