Polymarket BTC Up/Down odds vs the BTC price
Pull the Up token's minute bars for one 5-minute window from /polymarket/ohlcv and BTC's minute bars for the same window from /hyperliquid/ohlcv, and line them up by ts.
GET /v1/polymarket/ohlcv gives the Up token's minute bars for one 5-minute window in one call, priced as a probability, and GET /v1/hyperliquid/ohlcv gives BTC perp minute bars over the same window, in USD. Both carry ts in epoch milliseconds, so the rows line up. Take the market from /settlements/bulk: its slug holds the window start in epoch seconds and outcomes says which token is Up. The candle parameters are on Outcome candles.
Quick answer
Ask for the Up token's minute bars across the window.

Two clocks, two prices
to on /polymarket/ohlcv is inclusive and end on /hyperliquid/ohlcv is exclusive, so end the first a
millisecond early. A Polymarket bar exists only for a minute that traded. These markets settle on their own
price source, not on the Hyperliquid perp, so a move of a few dollars on the perp does not decide one. Use
the perp to see the move and /settlements for the result.
