Field notes

Toll402 combines a unified POST endpoint with MCP, JavaScript, and Python access paths. Its payment loop is explicit: a tool returns HTTP 402, the client signs a USDC transaction on Base, and the request retries automatically. The site lists 116 first-party tools alongside 2,123 external services, while its directory claims 4,617,569 businesses across 2,463 cities in 63 countries. A free trial allows 25 daily calls per IP for tools priced up to $0.005.
