Self-serve verification

One endpoint in.
One reproducible verdict out.

Submit an x402 endpoint URL (or its payTo wallet). We probe the live 402 challenge, grade the receiving wallet's settlement activity against our independent ledger, and return the verdict with the queries that produced it. Scope is stated on every result: this is wallet-level receiver activity, never a single-endpoint badge.

The four grades

Every verdict resolves to one of four.

Deterministic thresholds, versioned and published with the result. The same wallet and the same data window always produce the same grade.

Verified
Broad, diverse payer base; low concentration; low share of quality-flagged rows across the full window.
→ Proceed
Caution
Real activity, mixed signals: a narrow payer base, moderate concentration, or data-quality issues that cap the grade.
→ Proceed with limits
Not enough evidence
Too little history or too few measurable rows to judge. Not a negative finding — an honest one.
→ Wait or re-check
High concentration risk
A single payer dominates the clean volume, or quality-flagged rows dominate the activity. The apparent volume does not represent a payer base.
→ Do not rely
Scope, stated up front

The grade covers a wallet,
not a single endpoint.

Why every result says "wallet-level"

x402 payments settle to a payTo wallet. One wallet can receive for many endpoints — even many unrelated hosts — and their traffic is indistinguishable in the settlement data. A wallet grade rendered as a per-endpoint badge would let one well-behaved wallet "verify" every endpoint that happens to share it.

So we never do that. When the submitted endpoint's payTo wallet backs more than one known endpoint — or when sharing cannot be established — the result carries a prominent wallet-level warning, and the verdict is presented as receiver activity of the wallet, never as a clean endpoint grade. The shared-endpoint and host counts are included in the result so you can see exactly what the grade covers.
