Shares a payout wallet with 18 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Does a catalogue listing still match what the origin serves? Calls the resource with no payment, reads the price, network and payTo out of the 402 the origin itself returns, and compares them with the price the catalogue advertises. The 402 is the authoritative statement; the catalogue is a cache of one. Also separates two failures no catalogue reports: an origin that is gone, and an origin that answers but whose response headers exceed the 16384-byte ceiling Node applies to all response headers combined -- live, indexed and impossible to pay from a Node client. Required: resource. Optional: advertised_price. Honest note: demand for this route is not measured; it exists because the defect it reports was measured on our own surface first.

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
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
61

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 92% — how much probe evidence backs this score. A thin history is flagged, not hidden.

This payout wallet is shared: figures cover all 19 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.
