- polymarket_all_markets
Paid data plan required. Return every active Polymarket market across all categories, not only crypto. AI execution credits do not unlock this export. The text result is one LLM-readable line per market: MARKET_NAME | OUTCOME PRICES | DEADLINE | MARKET_ID. The sweep fails closed
- polymarket_search_markets
List Polymarket up/down crypto prediction markets for a coin. Returns market id, slug, window, status and timing. Use the returned id/slug with polymarket_get_market or polymarket_get_snapshots.
- polymarket_get_market
Fetch a single Polymarket market by id (market_id) or by slug. Provide exactly one of market_id or slug.
- polymarket_get_snapshots
Historical order-book snapshots (time series) for one Polymarket market. Use interval to downsample and include_orderbook for the full ladder. History depth is gated by plan.
- kalshi_search_markets
List Kalshi crypto markets (full yes/no depth, DepthFeed-exclusive). Every account plan; the keyless demo surface returns a 402 upsell.
- kalshi_get_orderbook
Latest yes/no order-book depth for a Kalshi market by ticker. Every account plan; only the keyless demo surface is refused.
- 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. This is the only history that exists for non-crypto Kalshi markets — Kalshi serves no historical order book — and it reaches back up to a year, far past the order-book capture.

Historical L2 depth snapshots (time series) for a Limitless market by slug. Every account plan; history is bounded by your plan window.
- 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 wi
- 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], …]}}}
- screener
Cross-venue top-of-book snapshot for all assets across Polymarket, Kalshi, and Binance — a one-shot overview of the current state. No arguments.
