Introduction: CoinCap is a useful tool for querying real-time pricing and marketing activities for more than 1,000 encrypted currencies.By collecting exchange data from thousands of markets, we can provide transparent and accurate data on asset prices and availability.This paper summarizes the basic operation and introduction of CoinCap API to query basic data of transactions on mainstream exchanges.

CoinCap is a useful tool for querying real-time pricing and marketing activities for more than 1,000 encrypted currencies.By collecting exchange data from thousands of markets, we can provide transparent and accurate data on asset prices and availability.This paper summarizes the basic operation and introduction of CoinCap API to query basic data of transactions on mainstream exchanges.

CoinCap provides 100 responses per page by default for all ports, and supports a maximum of 2,000 responses per page when requested.

CoinCap API services include RESTful API and WebSocket API.Querying data through the CoinCap API does not require a request key.

Base Query Statement:

api.coincap.io/v2/exchanges

Sample Node.js code:

const fetch = require('node-fetch');

fetch('https://api.coincap.io/v2/exchanges', {
    method: 'get',
}).then(response => response.json()
    .then(data => console.log(data.data)));

Returned JSON example:
