How often it was reachable when we probed it (weight 35%).
How quickly it answers when it is up — fast scores high (weight 20%).
Whether it serves over working TLS / https (weight 15%).
Whether the operator disclosed what it does — description, schema, identity (weight 15%).
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.

This payout wallet is shared: figures cover all 33 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.
Linked by wallet — likely same operator
