CoinGecko

API

Free Cryptocurrency Price, Market & Social Data API

Overview

CoinGecko API offers RESTful endpoints for real-time/historical cryptocurrency data: prices, market caps, trading volumes, developer stats (GitHub stars, forks), and social metrics (Twitter followers, Reddit activity). Responses are JSON-formatted. Key endpoints include /coins/markets (current market data), /coins/{id}/history (historical prices), /coins/{id}/developer_data (dev insights), and /coins/{id}/social_status (social trends). Ideal for building crypto trackers, portfolio apps, financial analytics tools, or integrating crypto data into websites. Basic usage requires no auth, with rate limits for free tiers.

script.js JS


fetch('http://www.coingecko.com/api')
  .then(res => res.json())
  .then(data => console.log(data))
