Shares a payout wallet with 178 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Find out what an x402 endpoint will charge before you pay it. Probes the endpoint, reads the challenge from the header or the body, and returns the decoded price, network, asset and payTo plus the declared input and output schemas. Never sends a payment. Only reviewed origins are reachable, and a redirect is refused rather than followed.

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
96

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

Latency
29

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

Security
96

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

Transparency
61

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

Activity
1

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 54% — 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 179 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.
