 * ## REST API for the BitMEX Trading Platform  [View Changelog](/app/apiChangelog)  -  #### Getting Started  Base URI: [https://www.bitmex.com/api/v1](/api/v1)  ##### Fetching Data  All REST endpoints are documented below. You can try out any query right from this interface.  Most table queries accept `count`, `start`, and `reverse` params. Set `reverse=true` to get rows newest-first.  Additional documentation regarding filters, timestamps, and authentication is available in [the main API documentation](/app/restAPI).  _All_ table data is available via the [Websocket](/app/wsAPI). We highly recommend using the socket if you want to have the quickest possible data without being subject to ratelimits.  ##### Return Types  By default, all data is returned as JSON. Send `?_format=csv` to get CSV data or `?_format=xml` to get XML data.  ##### Trade Data Queries  _This is only a small subset of what is available, to get you started._  Fill in the parameters and click the `Try it out!` button to try any of these queries.  - [Pricing Data](#!/Quote/Quote_get)  - [Trade Data](#!/Trade/Trade_get)  - [OrderBook Data](#!/OrderBook/OrderBook_getL2)  - [Settlement Data](#!/Settlement/Settlement_get)  - [Exchange Statistics](#!/Stats/Stats_history)  Every function of the BitMEX.com platform is exposed here and documented. Many more functions are available.  ##### Swagger Specification  [⇩ Download Swagger JSON](swagger.json)  -  ## All API Endpoints  Click to expand a section.
