How xPay works

From endpoint to revenue in minutes.

1. Register your endpoint

• Provide: API URL, HTTP method, price, token (SPL mint), and wallet

• Optional: custom auth headers, sample request/response

2. Get your xPay wrapper

• You receive https://api.usexpay.xyz/:username/:endpointName

• This URL enforces x402 payment automatically via Faremeter

3. Start earning

• Share the proxy URL or list it in the xPay marketplace

• Each successful 2xx response increments earnings

• Your endpoints also become MCP tools for AI agents

Notes

• Protocol methods for MCP (listing, initialize) bypass payment; tool calls are paywalled

• Sample request/response helps generate MCP tool schemas and better marketplace docs
