Shares a payout wallet with 24 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

European Central Bank euro foreign exchange reference rate for a pair - the latest published fix or any date in the last 90 days. The ECB publishes EUR/XXX only, so inverse and cross rates are computed by Eckari from the same fix and named in rate_derivation. Reference rates, one per TARGET working day around 16:00 CET, not tradable market rates. Source and reuse conditions travel in meta.attribution. Use when: What is the ECB reference rate for EUR to USD?

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
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 84% — 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.

Linked by wallet — likely same operator

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