AI agents buy real-time crypto intelligence autonomously. Pay per-query with STX. No signup. No subscription. Settled on Bitcoin.
The Problem
AI agents need data but can't access traditional providers.
CoinGecko $129/mo, Nansen $2,500/mo — AI agents only need a few queries. Monthly subscriptions are wasteful.
AI agents have no identity, can't create accounts, and don't have credit cards. They need autonomous payment.
Agent hits endpoint, auto-pays via STX micropayment, data delivered instantly. No signup, no subscription needed.

Real-time crypto intelligence — pay only when you need it.
Protocol
4 steps. Fully autonomous. No human needed.
Agent accesses /registry/feeds to browse available data feeds and pricing. Free!
Agent requests data. Server responds with HTTP 402 Payment Required — containing payment details.
x402 SDK signs an STX transaction from the agent's wallet and re-sends the request with payment proof. Fully autonomous!
Payment verified and settled on Stacks (Bitcoin L2). Data returned instantly. Everything provable on-chain.
