polymarket_get_market Fetch a single Polymarket market by id (market_id) or by slug. Provide exactly one of market_id or slug.

kalshi_get_snapshots Historical yes/no depth snapshots for a Kalshi market by ticker. Every account plan; history is bounded by your plan window.
kalshi_get_candles Hourly OHLC candles (yes bid, yes ask, traded price) plus volume and open interest for a Kalshi market.

bars OHLCV price bars for US equities and ETFs, Binance spot pairs, and perpetual futures. One minute is the finest resolution; 5Min, 15Min, 1Hour and 1Day are rolled up from it and say so with `derived`. Spell a crypto pair the way the venue does (BTCUSDT, not BTC) and a perpetual with a .P suffix (BTCU
backtest_paths Mid-price path per Polymarket market for backtesting, resampled to a fixed interval and bounded to each market's own lifetime so post-settlement books cannot leak in as risk-free fills. Returns {interval_seconds, markets:{<market_id>:{points:[[ts_ms, price_up, coin_price], …]}}} — up to 1000 points
