Free Crypto API — Real-Time Bitcoin & Ethereum Prices Without CoinMarketCap's $79/Month Plan

CoinMarketCap's free tier gives you 10,000 credits/month — sounds generous until you realize a single /v1/cryptocurrency/listings/latest call costs 1 credit per coin returned. Need top 100 coins? That's 100 credits per call, or ~3 calls per hour before you hit the wall. I built a lightweight alternative on Cloudflare Workers that aggregates CoinGecko's public data with edge caching. Here's what it does and how to use it. What You Get (Free Tier: 500 requests/month) Real-time prices for Bitcoin, Ethereum, and 10,000+ altcoins Market cap, 24h volume, price change percentages Trending coins (what's hot right now) Historical price data by date Exchange listings Global market statistics Sub-100ms latency via Cloudflare's 300+ edge locations Quick Start Python — Build a Portfolio Tracker import requests API_KEY = " your-rapidapi-key " BASE_URL = " https://crypto-data-api1.p.rapidapi.com " headers = { " x-rapidapi-key " : API_KEY , " x-rapidapi-host " : " crypto-data-api1.p.rapidapi.com " } #
