Built from first-party polling of real burns on Base, Arbitrum, and Optimism: every figure is a BOUNDED observation (burn -> first poll that saw the attestation complete), never an exact measurement, and the bound width ships alongside every distribution. Percentiles are withheld below an 8-measured-sample floor per (chain, path) bucket — a p95 over a handful of samples is arithmetic, not evidence. Unclassifiable samples are excluded, never bucketed; empty is reported as no_data, never as a low latency. The embedded EIP-712 PayloadAttestation proves which key signed these exact answer bytes — recompute keccak256(answer) and recover the signer before acting — never a claim that the measured latency will hold for your own transfer.","tags":["general","x402","usdc","base"],"inputModes":null,"outputModes":null},{"id":"earthquakes","name":"Earthquakes","description":"USGS recent earthquakes worldwide (M2.5+)","tags":["general","x402","usdc","base"],"inputModes":null,"outputModes":null},{"id":"merchant-screen","name":"Merchant Screen Oracle","description":"Know-Your-Agent (KYA) counterparty screening — merchant pillar. Pre-settlement merchant screen: signed ALLOW/WARN/BLOCK on a (domain, payTo, observed price) BEFORE an agent settles an x402 payment. ms-v1 ruleset over first-party signals measured at query time — RDAP domain age, live TLS handshake (cert age, issuer, SAN match), off-domain redirect probe, brand-similarity distance vs a committed known-brand corpus, and the merchant's own advertised x402 manifest price. Method disclosed per field; unmeasurable signals report unverified and only lower confidence. The verdict carries an embedded EIP-712 PayloadAttestation — recompute keccak256(answer) and recover the signer before acting. Trust boundary: the payTo and price are values you assert, not values we observe on your payment — the verdict is a point-in-time snapshot of the exact tuple you supplied, and it neither sees nor constrains the address you ultimately settle to. Before releasing funds compare answer.query against the 402 challenge you are about to pay (answer.query.address is lowercased — compare case-insensitively). The receipt proves provenance and integrity, not correctness. Every query is logged and retained: the domain, the payTo address and price you supplied, the verdict, and a summary of the signals behind it. Producing a verdict requires live outbound requests against the screened domain itself — the merchant may observe this traffic; screening is not covert.","tags":["commerce","x402","usdc","base"],"inputModes":null,"outputModes":null},{"id":"pkg-verdict","name":"Package Verdict Oracle","description":"Signed ALLOW/WARN/BLOCK on installing a package@version: OSV.dev malicious-corpus + typosquat distance + registry signals.

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.
