api.hyperextend.xyz/v1/candles/BTC/1m
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), and keep going while it is present, even after a short page. Candles lag ~2 days (reconstructed from the archive); omit start/end for the most-recent page.
