Infrastructure for Agents
Building the primitives that let AI agents interact with Bitcoin natively — query intelligence, make payments, hold value, and reason over the blockchain. All shipping through Contrabxnd.
A Model Context Protocol server that exposes real-time Bitcoin intelligence and our own node to any AI client. Claude Code, Cursor, Windsurf, or any MCP-compatible agent can query live signals, macro indicators, on-chain data, and Lightning through structured tool calls. AI doesn't just read data — it reasons over it.
- —25+ tools across intelligence, on-chain node queries, Lightning, and payments
- —Signals: Contrabxnd Score, FedWatch, net liquidity, SLR, ETF flows, MVRV, hash ribbon
- —Node: address/tx/block lookups, fund tracing, script decoding, fee estimation
- —API key auth with per-key rate limits; structured, MCP-compatible responses
HTTP 402 Payment Required — the internet's forgotten status code, finally put to work. Agents pay sats over Lightning to unlock premium endpoints: request the resource, get a 402 with a BOLT11 invoice, pay it, and retry with the preimage. No accounts, no subscriptions, no OAuth — just a Lightning payment proof.
- —Live L402 paywall on premium intelligence endpoints
- —Lightning-native — pay the invoice, retry with the preimage, data flows
- —No accounts or API keys required for agents
- —Discoverable pricing via the get_pricing MCP tool
Autonomous AI agents need autonomous money. We're building wallet infrastructure that lets agents hold, send, and receive Bitcoin over both on-chain and Lightning rails. An agent with a Contrabxnd wallet can pay for data, earn revenue for services, and manage its own treasury — no human in the loop.
- —On-chain + Lightning wallet per agent
- —Non-custodial where feasible (multi-sig with user backup)
- —Full transaction history and audit logging
- —Composable with MCP tools and x402 payments
Ask questions in English, get answers from the blockchain. Backed by our own full Bitcoin node and indexer, agents query addresses, trace fund flows, analyze mempool conditions, and decode scripts through MCP tools — no raw RPC required.
- —Address lookup, transaction tracing, and block analysis via MCP
- —Fund tracing across the transaction graph and script decoding
- —Real-time mempool analysis and smart fee estimation
- —On-chain valuation: realized price, MVRV, and HODL waves
AI agents are the next class of economic actor. They'll need money that moves as fast as they think — programmable, permissionless, and borderless. Bitcoin over Lightning is that money. We're building the infrastructure so agents can earn it, spend it, and reason over it.
