PayPerByte

Gold402 Verified. Hand-reviewed and on the curated list — curation is the bar. The stamp means a human read this entry and the endpoint answered when we knocked. It is not a delivery test: we have not paid this service and graded what came back, so treat it as "reachable and speaks the protocol," never as "this is worth the money."

Eleven pay-per-call USDC data feeds and oracles on Base mainnet: weather, earthquakes, CCTP v2 attestation-latency distributions, threat-intel, package/runtime vulnerability checks, and Know-Your-Agent 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.
