Summary
This connects Claude to blockchain-based data products on Base mainnet using the x402 pay-per-call protocol. You get access to three specific datasets: OFAC sanctions lists, METAR aviation weather reports, and US property records. Each query costs tokens on-chain, so you're paying for actual data retrieved rather than subscription access. Reach for this when you need real-time regulatory, weather, or property data in your workflows and want to pay only for what you use. The blockchain settlement means no API keys or traditional auth, just wallet transactions for each call.
