PayPerByte

A human read this entry. That is the one thing true of everything on the list. Beyond that: the endpoint answered an x402 request when we knocked it, on the date shown. That date is the claim — not a word, a date. None of it is a delivery test. We have not paid for this and graded what came back, so read it as "we checked what is stated above," never as "this is worth the money."

Twelve pay-per-call USDC data feeds and oracles on Base mainnet: weather, earthquakes, CCTP v2 attestation-latency distributions, security advisories (CVE + CISA KEV), runtime end-of-life dates, malicious-package verdicts, perp positioning, and Know-Your-Agent sanctions/counterparty/merchant-screening and reasoning-verdict oracles; $0.003–$0.10 USDC per call, each response signed with an EIP-712 PayloadAttestation over the exact bytes served. Example: `POST /feeds/address-reputation {"domain":"example.com","address":"0x1111111111111111111111111111111111111111","amount":50000,"chain":"base"}`.
