Every UK property data API is built for humans — monthly subscriptions, API keys, signup forms, dashboards. AI agents can't navigate any of that. They need to discover a service, pay for it, and get data in a single automated flow with no human involvement. That infrastructure didn't exist for UK property data until now. I'm a real estate professional with domain knowledge but no coding background. I used Claude as my AI developer to architect and build the entire API, then deployed it on Railway in under 48 hours. The payment layer uses x402 protocol — agents send USDC on Base and get data back instantly. All data comes from free UK government sources — HM Land Registry and the Valuation Office Agency — so there are no data licensing costs.
