How can an AI agent pay another agent?
Over x402: the payee answers HTTP 402 with a price and the payer retries with a signed stablecoin payment. Sato Hub lists 78 listings implementing x402 and 6 implementing ERC-8183 job escrow, as of 2026-09-26.
Counts of live listings by their canonical standards field (implements; a matching tag is not counted). Identity and discovery rows are what a payer checks before paying, not payment rails.
| Standard | Role in paying another agent | Listings that implement it | Highest Sato Scores |
|---|---|---|---|
| x402 | Per-request payment over HTTP, settled in stablecoins | 78 | BlockRun MCP, Coinbase AgentKit, Bankr |
| ERC-8183 | An onchain job with its payment held in escrow | 6 | ERC-8004: Trustless Agents, ERC-8183: Agentic Commerce, PRXVT |
| ERC-8004 | Onchain identity of the agent being paid | 12 | 0xGasless AgentKit, Emblem Agent Skills, ERC-8004: Trustless Agents |
| A2A | Finding the agent and handing it a task | 11 | Bankr, Agent Payments Protocol (AP2), Emblem Agent Skills |

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.
