# SDK Reference

The reference for the GoBTC Pay SDKs: what each one exposes, from packages down to methods, types, events, and errors.

### Available SDKs

| SDK         | Package                 | Reference             | Status    |
| ----------- | ----------------------- | --------------------- | --------- |
| POS API SDK | `@gomining/pos-api-sdk` | POS API SDK reference | Published |

The **POS API SDK** is the official client for the POS API surface. The same package works
 both on a server and in the browser, so you create a payment, show the QR, and
 track it until it settles from either place.

See the [POS API SDK](/sdk-reference/pos-api-sdk.md) reference for the full API.

## 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.gobtcpay.com/sdk-reference.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.
