Shares a payout wallet with 12 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Buying on x402: what 141 audited endpoints say before you send USDC. Conformance audit of 141 live x402 endpoints: 2.1% pass, 32 invisible to crawlers, and the one check that separates payment from payment theater. Free: the three failure classes. Paid: the six-check matrix + seller preflight. One payment returns the full text, and the creator is paid as it is used.

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

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
36

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

Activity
not yet measured

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.

See the scoring methodology for exactly how each number is computed.

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.
