ERC-8257 Agent Tool Registry · Base · endpoint: tools.snapsus.com

How an agent calls a tool

  1. Find it in OpenSea's onchain registry, or load the manifest directly.
  2. POST the endpoint with a JSON body. With no payment it returns 402 and the price.
  3. The agent signs an x402 USDC payment and retries, and gets the JSON result back. The facilitator settles it, so there is no gas to pay. If a call fails before settlement, nothing is charged.
