Complete JavaScript & Node.js SDK for BitMart REST APIs & WebSockets:
- Complete integration with all BitMart APIs.
- TypeScript support (with type declarations for most API requests & responses)
- Robust WebSocket integration with configurable connection heartbeats & automatic reconnect then resubscribe workflows.
- Browser-friendly HMAC signature mechanism.
- Automatically supports both ESM and CJS projects.
npm install --save bitmart-api

Most methods pass values as-is into HTTP requests. These can be populated using parameters specified by BitMart's API documentation, or check the type definition in each class within this repository.
- Create API credentials within your account on BitMart's website, if you haven't done so already.
- Import/require the module
- Create an instance of the REST client
- Call the function corresponding to the API call and handle the returned promise.
const { RestClient } = require('bitmart-api');
const client = new RestClient({
apiKey: "yourAPIKeyHere",
apiSecret: "yourAPISecretHere",
apiMemo: "yourAPIMemoHere
});
client.getAccountBalancesV1()
.then((result) => {
console.log('getAccountBalancesV1 result: ', result);
})
.catch((err) => {
console.error('getAccountBalancesV1 error: ', err);
});This can be set two levels:
- Per method: if provided in a method, will be used instead of the global default
- Global default: this will apply by default to any api call that supports recvWindow, if no recvWindow is provided in the method call.
Authentication involves HMAC signing on the request, using API credentials. Internally, this SDK uses the Web Crypto API. The REST client also supports injecting a custom sign function, should you wish to use an alternative (such as node's native & faster createHmac).
Refer to the fasterHmacSign.ts example for a demonstration.

This connector is fully compatible with both TypeScript and pure JavaScript projects, while the connector is written in TypeScript. A pure JavaScript version can be built using npm run build, which is also the version published to npm.
The version on npm is the output from the build command and can be used in projects without TypeScript (although TypeScript is definitely recommended).
Note: The build will output both ESM and CJS, although node should automatically import the correct entrypoint for your environment.
- src - the whole SDK written in TypeScript
- dist - ESM & CJS builds of the SDK in JavaScript (this is published to npm)
- examples - some implementation examples & demonstrations.
