GET /v1/candles/BTC/1m
unprobed
OHLCV candles over a window — main, spot, HIP-3 (e.g. xyz:AAPL, xyz:SP500) and HIP-4 outcome markets; intervals 1m to 1d. Priced per row ($0.00001 base for main/spot, $0.000025 premium for HIP-3/HIP-4); paginate with the X-Next-Start header (≤5000 rows/page). Candles lag ~2 days (reconstructed from the archive); omit start/end for the most-recent page.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
