x402

Pay per call

m3o.com is a machine-readable endpoint for agents and software clients, rather than a website for people to browse.

Use public services from your own agent with x402 payments. You do not need a Micro account for public paid tools. Private account data still requires authorization.

How it works

1. Choose a tool from the catalogue and call it through MCP or the HTTP API.
2. A paid call returns HTTP 402 with payment requirements.
3. Your x402-compatible client signs the payment and retries the request.

Free public tools do not require payment. An ordinary MCP client needs x402 payment support to use this flow.
