How can an AI agent pay another agent?
Pay per request over x402 (HTTP 402, then a signed stablecoin payment); hold a job's payment in escrow with ERC-8183. Sato Hub lists 96 implementing x402 and 6 ERC-8183, as of 2026-11-11.

Counts of live listings by their canonical standards field (implements; a matching tag is not counted). x402 and ERC-8183 move money. ERC-8004 and A2A identify and find the payee and hand it a task; neither moves money, so they are what a payer checks before paying, not payment rails.

Counts of live records by their canonical standards field — x402 and ERC-8183 as payment rails, ERC-8004 and A2A as the identity and discovery a payer checks first — each ordered by Sato Score.
Every answer on this page is produced by one named function over Sato Hub's live records on the date shown. Nothing is typed by hand, no figure is carried over from a previous day, and an answer with nothing behind it says unknown rather than zero. The Sato Score measures how open, active and verifiable a project is — it is not a safety, quality or returns grade.
