x402 Agent Data Gateway — Sample Outputs
Real sample responses from a live, pay-per-call data gateway for AI agents. Your agent does an HTTP GET,
gets a 402 Payment Required, pays a few cents of USDC on Base (x402), and receives clean structured JSON.
No API keys, no signup, no subscription. This dataset shows exactly what you get back.
Why
Autonomous agents need to enrich a company by domain or profile a wallet before they transact, but the good sources (Clearbit, Apollo, Nansen) are signup- and KYC-gated — unusable by an autonomous agent. This gateway is the frictionless, pay-per-call alternative.
