Bitfinex RESTv1 & RESTv2 APIs for Node.JS

A Node.JS reference implementation of the Bitfinex REST APIs

To use, construct a new instance of either the RESTv1 or RESTv2 classes. All API methods return promises and accept a callback as the last parameter; the callback will be called with (error, response).

To minimize the data sent over the network the transmitted data is structured in arrays. In order to reconstruct key / value pairs, set opts.transform to true when creating an interface.

Features

• Official implementation
• REST v2 API
• REST v1 API

Installation

  npm i --save bfx-api-node-rest

Quickstart

const { RESTv2 } = require('bfx-api-node-rest')
const rest = new RESTv2({ transform: true })

// do something with the RESTv2 instance

Docs

Documentation at https://docs.bitfinex.com/v2/reference

Example

const { RESTv2 } = require('bfx-api-node-rest')

const rest = new RESTv2({
  apiKey: '...',
  apiSecret: '...',
  authToken: '...', // optional, has priority over API key/secret
  url: '...',       // optional
  transform: true,  // to have full models returned by all methods
  agent: null,      // optional proxy agent
})

rest.candles({
  timeframe: '1m',
  symbol: 'tBTCUSD',
  query: {
    start: Date.now() - (24 * 60 * 60 * 1000),
    end: Date.now(),
    limit: 1000,
  }
}).then((candles) => {
  // ...
}).catch((err) => {
  console.log(err)
})

NOTE: v1 REST and WS clients

Both v1 client classes & server APIs have been deprecated, and will be removed. In the meantime, some methods available via RESTv1 have been exposed on RESTv2 to prevent future migration issues. Although the underlying implementation of these methods is likely to change once they are fully ported to v2, the signatures should remain the same.

FAQ

nonce too small

I make multiple parallel request and I receive an error that the nonce is too small. What does it mean?

Nonces are used to guard against replay attacks. When multiple HTTP requests arrive at the API with the wrong nonce, e.g. because of an async timing issue, the API will reject the request.

If you need to go parallel, you have to use multiple API keys right now.
