Address Reputation Oracle

Agentic-payments go/no-go verdict: synchronous signed ALLOW/WARN/BLOCK for (domain, receiving address, amount, chain) BEFORE releasing USDC. ar-v1 ruleset over RDAP/TLS/DNS/Wayback domain signals + on-chain receiving-address signals + curated known-bad blocklist. The verdict carries an embedded EIP-712 PayloadAttestation — recompute keccak256(answer) and recover the signer before acting. Scope: screens the counterparty tuple you supply — not identity verification of the calling agent.

Sanctions Screen Oracle
$0.100POST https://www.payperbyte.io/feeds/sanctions-screenKnow-Your-Agent (KYA) counterparty screening — sanctions pillar. Signed, version-pinned OFAC SDN + Consolidated screening on an address or name; every answer embeds the pinned list-state (date + sha256) it was judged against. Primary source: official U.S. Treasury Sanctions List Service exports incl. the digital-currency address annex, parsed and content-sha256-pinned first-party — not a resold vendor list. Scope: screens the counterparty you supply — not identity verification of the calling agent. Receipt deadline: this feed's EIP-712 receipt is minted with a 10-year freshness window (not the platform's usual 300s), by design — evidence-grade compliance records need to stay independently verifiable long after the screening decision itself has aged. This is a durability choice, not a licence to act on stale data: the receipt still proves only which key signed which exact bytes — it carries no signed observation time, so it never establishes WHEN the screening ran (an external existence-in-time anchor is what would), and never that the screening result is still current. Re-screen before relying on an old answer for a new decision.
Reasoning Verdict Oracle (local LLM)
$0.100POST https://www.payperbyte.io/feeds/reasoning-verdictVerify-before-act risk oracle: POST an action context (message, payload, proposal, payee, tool-call) and get a signed ALLOW/WARN/BLOCK/ABSTAIN verdict + 0-100 safe-to-proceed score + reasons from a LOCAL model (no data egress). The verdict carries an embedded EIP-712 PayloadAttestation — recompute keccak256(answer) and recover the signer before acting. Advisory: the receipt proves provenance/integrity, not correctness.
