Biscoint API Node

🌎 This documentation is also available in the following languages: PT-BR

NodeJS library for interacting with Biscoint's API. In order to call private methods, you'll need a Biscoint verified account to generate the API key and secret.

Biscoint is a cryptocurrency marketplace that allows trading BTC and another assets in multiple exchanges with a single account.

Example

Check out biscoint-arbitrage-bot, for it showcases the use of many of the methods in this library in an arbitrage bot application.

Install with NPM

  npm i biscoint-api-node

Install with Yarn

  yarn add biscoint-api-node

Instantiate Biscoint class

import Biscoint from 'biscoint-api-node';


// configure here with your keys for private calls, public calls don't need valid keys
const bc = new Biscoint({
  apiKey: 's4t0sh1n4k4m0t0',
  apiSecret: 's4t0sh1n4k4m0t0',
  // apiTimeout: 9000,
});

Optionally, you can uncomment the apiTimeout line to specify the request timeout in milliseconds you want. If not specified the default timeout will be 5000ms.

All methods return a Promise.
