Endpoint
api.eckari.com/v1/fx/reference-rate
European Central Bank euro foreign exchange reference rate for a pair - the official daily fix used for accounting, invoicing and reporting - latest or any date in the last 90 days. The ECB publishes EUR/XXX only, so inverse and cross rates are computed from the same fix and named in rate_derivation. One fix per TARGET working day, not a tradable market rate. Use when: Convert or report an amount at an official daily rate both sides of a contract can verify against the ECB.
Score
The score is built from observations we collect ourselves: how the endpoint responds, what the envelope contains, how stable the price and the recipient are, who pays and how often. It is deterministic — the same input always produces the same result.
We do not publish the exact methodology yet. If you own this endpoint, write to us and we will show you, item by item, what drags the score down.

Is this your endpoint?
The score is built only from public observations. If something we recorded is wrong — say our prober hit you during maintenance — write to us. We will recheck and publish your reply next to the score.
We do not delete accurate observations. The prober makes at most one request per second per host and only asks for the payment challenge — it never pays and never takes content.
