More live, ground-truth data than any other x402 service — public records, finance & SEC filings, crypto & web3, security & CVEs, legal, medical, weather, geocoding, and B2B/EDI. A full AI gateway: chat, image, and multi-model consensus across every major model, priced per request in the 402 before you pay. And agent infrastructure with no account: wallet-scoped storage (kv/docs/vectors/files), locks, queues, scheduled callbacks, pub/sub, and watchers that push signed webhooks when the world changes. Pay per call in USDC on Base or Solana via x402 — no API keys, no signup, no subscription. The first x402 API with upto billing: on AI endpoints, authorize the quoted max and settle only your actual usage. Try before you buy: add ?trial=1 (or header X-2s-Trial: 1) to any endpoint for one free real call per endpoint per hour — no wallet needed.
