Documentation Overview

BTCFi API

Bitcoin Intelligence API for AI Agents

License: MIT Version

Live at btcfi.aiindigo.com Β· Built by AI Indigo Β· GitHub


BTCFi API is an agent-native Bitcoin intelligence platform providing 80+ endpoints across Bitcoin, Ethereum, Solana, Lightning Network, Runes, and Taproot Assets. Powered by x402 micropayments β€” pay $0.01–$0.05 per query in USDC, no API keys or subscriptions required. CoinGecko integration provides multi-currency pricing (38 fiat currencies). AI agents discover endpoints at /llms.txt and integrate via MCP, SDK, or raw HTTP.

Free Tier

100 calls/day per IP β€” no signup, no API keys, just make a request:

Terminal
curl https://btcfi.aiindigo.com/api/v1/fees
config.json
{
  "fastest": 12,
  "30min": 8,
  "1hr": 5,
  "economy": 3,
  "fastestUSD": "$2.40",
  "recommended": "8 sat/vB"
}

Quick Start

AI Agents (MCP):

Terminal
npx @aiindigo/btcfi-mcp

SDK:

Terminal
npm install @aiindigo/btcfi
server.ts
import { BTCFi } from "@aiindigo/btcfi";

const btcfi = new BTCFi({ network: "base" });
const fees = await btcfi.fees();
const risk = await btcfi.intelligence.risk("bc1q...");

Raw HTTP:

bash
# Free endpoint β€” no auth needed
curl https://btcfi.aiindigo.com/api/v1/mempool

# Paid endpoint β€” requires x402 micropayment
curl -X GET https://btcfi.aiindigo.com/api/v1/intelligence/whales \
  -H "X-Payment: <x402-payment-proof>"
