Quickstart

This guide will walk you through everything you need to quickly integrate our API into your projects and start accessing live cryptocurrency data.

Step 1: Understand the Basics

The CoinCap API uses RESTful architecture and delivers data in JSON format. All requests are made using the GET method, ensuring compatibility with most development environments.

Base URL:

All API endpoints are accessed via:

https://api.coincap.io/v2/

Step 2: Setup Your API Key (Optional)

While CoinCap API supports unauthenticated usage, requesting an API key unlocks higher rate limits and additional features.

Without API Key:

200 requests per minute Access to 11 years of historical data

With API Key:

500 requests per minute Enhanced access to historical data

Request API Key

To obtain your API key, request your API key here. Once received, use it as a Bearer Token in your headers:

Authorization: Bearer YOUR_API_KEY

Step 3: Send Your First Request

Now that you’re ready, try a basic API call to fetch the latest cryptocurrency data:

GET https://api.coincap.io/v2/assets

This request will return a list of cryptocurrencies, including names, symbols, prices, and market data.

The CoinCap API provides a range of endpoints for data retrieval, including:

• Assets: Comprehensive data on cryptocurrencies
• Markets: Information about trading pairs across exchanges
