The (most) everything API — 570+ pay-per-call endpoints for AI agents: USPTO patents + trademarks, US court opinions, SEC EDGAR, Congress, FDA, CVE/security intel, OFAC sanctions screening, GLEIF/KYB identity, academic papers, geocoding, weather, vehicles, prediction markets, sports, identity crosswalks, an OpenAI-compatible AI gateway (chat/image/model council), and stateful agent primitives (storage, vector search, locks, queues, cron, pub/sub, watchers). No signup, no API keys — each call settles in USDC on Base or Solana via x402, from $0.001, with the exact price quoted in the 402 challenge before you pay.
