https://x402.halowerk.com/receipt/verify

Shares a payout wallet with 376 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Cryptographic verification of the offer-receipt extension of x402. Accepts a signed offer in eip712, jws or eip191 form — either bundled as {format, payload, signature} or as payload plus a separate signature — and an optional signed receipt. Recovers the signer, compares it with the payTo of the offer, compares receipt and offer field by field and names every divergence with the value on each side, checks whether the offer has expired and whether the receipt timestamps are plausible against sta

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
88

How often it was reachable when we probed it (weight 35%).

Latency
100

How quickly it answers when it is up — fast scores high (weight 20%).

Security
100

Whether it serves over working TLS / https (weight 15%).

Transparency
67

Whether the operator disclosed what it does — description, schema, identity (weight 15%).

Activity
0

Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).

Confidence 100% — how much probe evidence backs this score. A thin history is flagged, not hidden.

Operator context is derived from public RDAP/TLS records and unverified. Company and country are only available for endpoints that publish them (an OV/EV TLS certificate or a non-redacted domain record); most endpoints are CDN-fronted and disclose neither.

This payout wallet is shared: figures cover all 377 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.
