polymarket_all_marketsread-onlyPaid 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 if complete pagination cannot be verified and includes timestamp, count, source-page count, and SHA-256.
polymarket_search_marketsread-onlyList 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_marketread-onlyFetch a single Polymarket market by id (market_id) or by slug. Provide exactly one of market_id or slug.
polymarket_get_snapshotsread-onlyHistorical 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_marketsread-onlyList Kalshi crypto markets (full yes/no depth, DepthFeed-exclusive). Every account plan; the keyless demo surface returns a 402 upsell.
kalshi_get_orderbookread-onlyLatest yes/no order-book depth for a Kalshi market by ticker. Every account plan; only the keyless demo surface is refused.
kalshi_get_snapshotsread-onlyHistorical yes/no depth snapshots for a Kalshi market by ticker. Every account plan; history is bounded by your plan window.
kalshi_get_candlesread-onlyHourly 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. `price` is null in periods with no trade. Every account plan; history is bounded by your plan window.
limitless_search_marketsread-onlyList currently-open Limitless (Base CLOB) markets, DepthFeed-exclusive. Every account plan; only the keyless demo surface is refused.
limitless_get_orderbookread-onlyLatest L2 depth (bids desc / asks asc) for a Limitless market by slug. Every account plan; only the keyless demo surface is refused.
limitless_get_snapshotsread-onlyHistorical L2 depth snapshots (time series) for a Limitless market by slug. Every account plan; history is bounded by your plan window.
barsread-onlyOHLCV 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 (BTCUSDT.P) — spot and perp are different instruments at different prices. BTCU, ETHU and WLDU are each b
backtest_pathsread-onlyMid-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 per market. Pass 1 to 50 market ids from polymarket_search_markets. History is bounded by the plan w
