Data ✓ VERIFIED

verified until 2026-08-17

PayPerByte is a pay-per-call data gateway for AI agents — 22 first-party feeds and decision oracles billed in USDC over x402 on Base mainnet. A wallet, not an API key; no token. Every paid 200 carries a signed EIP-712 provenance receipt (X-BYTE-Attestation) so an agent can verify the data before it acts. Coverage spans DeFi/markets, weather, earthquakes, security advisories, code/runtime status, and decision oracles. Flagship: the Address Reputation Oracle — a signed ALLOW/WARN/BLOCK verdict on a receiving address before an agent releases funds ($0.05/call). Per-byte pricing from $0.003; settled in USDC via the Coinbase CDP facilitator.

Pay from $0.003 to $0.10 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.

compliance A (14/14)

14 of 14 x402 conformance checks pass. Full checklist below.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Top buyer share is a concentration signal, not part of the ranking score.

OVER TIME

All charts use the 30d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/payperbyte/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
