GET /v1/trades/BTC

unprobed

Raw market trades over a time window — the live hot tier (~24h) plus S3 read-through for older history (archive from 2025-05-25), merged. Each row mirrors HL's WsTrade verbatim, including the buyer/seller addresses (`users`) and the trade `hash`. Priced per asset-hour ($0.015 base, $0.03 HIP-3/HIP-4) plus $0.05 per uncached archive hour pulled (warms the cache); ≤24 asset-hours/request.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
