Provides access to 31 Bitcoin data and intelligence endpoints, including real-time mempool status, fee predictions, whale alerts, and risk scoring for Bitcoin addresses.
Integrates with Coinbase as a facilitator for fee-free x402 micropayments on the Base network to access data endpoints.
Utilizes the Solana network to process NLx402 micropayments for pay-per-query access to Bitcoin intelligence and data services.
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.
