# 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

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.usexpay.xyz/xpay-overview/how-xpay-works.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
