Public US-government reference data, sold to AI agents one record at a time over x402.
How this works. Each API below has free keyword search and free metadata. The full record is a paid call: your agent requests it, gets an HTTP 402 with the price and terms, pays USDC on Base mainnet, and receives the record. The 402 carries x402 Bazaar discovery data, so a Bazaar-aware agent can pay without reading this page.
