API Documentation

bitFlyer Lightning offers two styles of API, the HTTP API and Realtime API.

Regions

API functionality may be limited by region. Specific products, such as market or future, may not be available in every region, specific order pairs may be limited to a specific region as well.

The U.S. may only trade BTC_USD at this time. European accounts may only trade BTC_EUR at this time.

HTTP API

Japan Endpoint URL: https://api.bitflyer.com/v1/ U.S. Endpoint URL: https://api.bitflyer.com/v1/ Europe Endpoint URL: https://api.bitflyer.com/v1/

You can try out our API at the API Playground.

API Limits

Please be aware of the HTTP API usage limits below.


Authentication

Authentication is required to callout the Private API. After login, on the developer's page, use the issued API key and API secret.

Include the following information in the HTTP request header.

ACCESS-SIGN is the resulting HMAC-SHA256 hash of the ACCESS-TIMESTAMP, HTTP method, request path, and request body concatenated together as a character string, created using your API secret.

// Node.js sample
var request = require('request');
var crypto = require('crypto');

var key = '{{ YOUR API KEY }}';
var secret = '{{ YOUR API SECRET }}';

var timestamp = Date.now().toString();
var method = 'POST';
var path = '/v1/me/sendchildorder';
var body = JSON.stringify({
    product_code: 'BTC_JPY',
    child_order_type: 'LIMIT',
    side: 'BUY',
    price: 30000,
    size: 0.1
});

var text = timestamp + method + path + body;
var sign = crypto.createHmac('sha256', secret).update(text).digest('hex');

var options = {
    url: 'https://api.bitflyer.com' + path,
    method: method,
    body: body,
    headers: {
        'ACCESS-KEY': key,
        'ACCESS-TIMESTAMP': timestamp,
        'ACCESS-SIGN': sign,
        'Content-Type': 'application/json'
    }
};
request(options, function (err, response, payload) {
    console.log(payload);
});

API key permissions

When you set up an API key, you can set the permissions for each key. In order to access a list of the permissions held by the API key, please use the Get API permissions API.

Pagination

The API that returns multiple results can read within the specified range.
