Shares a payout wallet with 144 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Official US Treasury reporting rates of exchange — government FX reference rates for ~170 currencies, in units of foreign currency per 1 USD, for the latest quarter. Use for accounting-grade and exotic-currency conversion the market /api/v1/forex feed lacks. Filter with `?currency=Euro`. Updated quarterly. From the US Treasury (FiscalData). From x402stock

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
61

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

Activity
6

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.

This payout wallet is shared: figures cover all 145 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

On-chain agent identity and the x402 endpoint that shares its settlement wallet.
