# Get Masterpass REST BIN Number Page context

Returns the context for the Masterpass REST BIN number page. The card details are collected on the client side via the Masterpass JS SDK; only the BIN (and a flag indicating whether the card is a stored Masterpass card) is sent back to the server so it can identify the card type and determine the available installment options.

**Preconditions**:

* Basket must not be empty
* Payment option must be of Masterpass REST type (`is_masterpass_rest()`)

**Page Context**:

* Returns an empty object `{}`. No additional data is exposed at GET time — the card data flow runs through the Masterpass JS SDK.

**Step Completion**: This page is considered already completed (`is_already_done`) when both of the following are true:

* `pre_order.card_info` is populated, **and**
* The selected payment option is Masterpass REST.

**available\_for\_post\_order**: `true`

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://apidocs.akinon.com/commerce-openapis/checkout/masterpass-payment/get-masterpass-rest-bin-number-page-context.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.
