The Most Intuitive
Bitcoin API
Bitcoin API is a high-performance market data interface providing real-time and historical Bitcoin data via REST and WebSocket. Designed for developers and AI agents, it delivers exchange prices, OHLCV candles, and on-chain metrics with minimal latency. It is the ultimate tool for building wallets, trading bots, and financial dashboards.
async function getBitcoinPrice() {
const response = await fetch("https://bitcoin-api.net/api/v1/prices/current", {
headers: {
"Content-Type": "application/json",
"Authorization": "Bearer your_api_key_from_profile"
}
});
const data = await response.json();
console.log(data);
}// Output: { price: 65432.10, time: "2026-04-12T12:00:00Z" ... }Everything you need to build crypto apps
Designed for developers who need power and simplicity. We handle the complexity of the blockchain so you don't have to.
Real-time Data
Most data is taken from direct sources i.e. Centralized/Decentralized exchanges and blockchain via WebSocket API and REST.
Developer Friendly
Every endpoint is well documented with examples and designed with DX in mind - so you spend time building, not reading.
AI Agents Friendly
Built-in MCP server and structured documentation make it effortless for AI agents to discover and use every endpoint.

async function getTransactions() {
const response = await fetch("https://bitcoin-api.net/api/v1/transactions", {
headers: {
"Content-Type": "application/json",
"Authorization": "Bearer your_api_key_from_profile"
}
});
const data = await response.json();
console.log(data);
}// Output: { price: 65432.10, time: "2026-04-12T12:00:00Z" ... }API Key Settings
Manage client-side permissions
Limits are applied per individual IP address. If a user abuses your key, they are rate-limited locally without affecting your application's global quota.
Connect Directly on the Client—No Backend Required
Why waste time setting up and hosting an intermediate server just to protect your credentials? With Bitcoin API, you can query market data and manage WebSocket connections directly from your client-side code.
IP-Based Abuse Protection
Set a maximum requests-per-minute limit from a single IP address on your API key. One malicious visitor will only block themselves, keeping your global API key limits and other users completely unaffected.
Faster Deployments & Lower Costs
Build SPA apps, browser extensions, static sites, or mobile applications without setting up a single line of backend middleware. Save on server costs and speed up your time to production.
Real-Time Client-Side Updates
Establish secure WebSocket connections straight from the browser to receive instant price updates and on-chain metrics with sub-millisecond network overhead.
All Endpoints are Free.
Only Boost What You Need.
Why pay for bloated monthly subscription plans that bundle hundreds of endpoints you'll never call? Every single REST and WebSocket endpoint on Bitcoin API is free by default, with generous rate limits. Scale only the routes driving your core business.
Zero Waste, Low Money Burn Rate
Keep your infrastructure lean. Keep 95% of your API integrations on our free tier, and selectively pay a small monthly fee only to boost the specific endpoints that require heavy high-frequency updates.
Zero-Config Gateway Level Boosts
No code adjustments, no config file updates, and no downtime. Boosts are linked instantly to your API key at the API gateway layer. Simply toggle a boost and watch the limits upgrade in real-time.
Scale and Downscale Effortlessly
Need higher throughput for a weekend marketing campaign or a high-volatility event? Instantly upgrade your route limits, and downgrade them back to the free tier whenever you want via Stripe.
