Bitcoin Intelligence API for AI Agents
Live at btcfi.aiindigo.com · Built by AI Indigo · 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 — 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.
100 calls/day per IP — no signup, no API keys, just make a request:
curl https://btcfi.aiindigo.com/api/v1/fees
{
"fastest": 12, "30min": 8, "1hr": 5, "economy": 3, "fastestUSD": "$2.40", "recommended": "8 sat/vB" }
AI Agents (MCP):
npx @aiindigo/btcfi-mcp
SDK:
npm install @aiindigo/btcfi
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:
# Free endpoint — no auth needed
curl https://btcfi.aiindigo.com/api/v1/mempool
curl -X GET https://btcfi.aiindigo.com/api/v1/intelligence/whales \ -H "X-Payment: "
