Bitcoin data for AI agents. 27 tools with x402 micropayments. No API keys needed.
Bitcoin data for AI agents. 27 tools with x402 micropayments. No API keys needed. That is what the btcfi api mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
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.
Configuration is passed through the environment: UPSTASH_REDIS_REST_URL, UPSTASH_REDIS_REST_TOKEN, X402_FACILITATOR_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by aiindigo925; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against BTCFi API's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
