• kalshi_candlesticks ~556 tokens
  Price history (OHLC candles) for UP TO 100 Kalshi markets over ONE shared window, in ONE call — Kalshi's batch candlestick endpoint (`GET /markets/candlesticks`). This is the comparison tool: every bucket of a Fed or CPI event on one timeline, or the same question across several strikes, without the
• kalshi_event ~572 tokens
  AUTHORITATIVE odds from Kalshi — the only CFTC-regulated US prediction-market exchange (US persons CAN legally trade here, unlike Polymarket). Returns one event with ALL its child markets nested: event title + each market's ticker, subtitle, price, volume. Use when you need the full partition for an
• kalshi_event_live_data ~596 tokens
  The REAL-WORLD measurement an event settles against, next to the odds — Kalshi's event live-data feed (`GET /live_data/events/{event_ticker}`). This is the thing you cannot get by calling any other Kalshi endpoint: for a crypto event it is the underlying BTC/ETH price track from the settlement index
• kalshi_events ~475 tokens
  List/browse Kalshi events (event = a question with one-or-more child markets, e.g. "Fed funds rate after Oct 2026 meeting?" with 11 markets, one per rate bucket). Filter by status (open / settled), series_ticker (KXFED, KXBTC, KXCPI, etc.), or category (Politics, Economics, Financials, Crypto, Clima
• kalshi_exchange_status ~75 tokens
  Exchange-level status: is the trading floor open, are deposits/withdrawals enabled, any scheduled maintenance. Cheap check before a batch script.
• kalshi_game_stats ~414 tokens
  Live scoreboard and play-by-play for a sports game Kalshi has markets on, keyed by MILESTONE id (not event ticker) — Kalshi's `GET /live_data/milestone/{id}` plus `/game_stats`. Returns the current state (score, period/inning, status, last play, winner once final) and the play list, newest-first, ea
• kalshi_macro ~199 tokens
  Friendly-name shortcut for the most-asked Kalshi macro series: "Fed" (FOMC rate buckets), "BTC" (Bitcoin price ranges), "ETH" (Ethereum), "CPI" (monthly inflation), "GDP" (quarterly growth), "SP500" (S&P 500 EOY close), "Recession" (NBER recession calls). Returns the soonest-expiring open event for
• kalshi_market ~259 tokens
  AUTHORITATIVE detail for one Kalshi market by ticker (e.g. "KXFED-26OCT-T3.50"), live OR long-settled — Kalshi drops older markets from its live endpoints (they 404 there), and this falls through to Kalshi's historical archive and says which answered in `source`. Returns the rules text (so you know
• kalshi_markets ~763 tokens
  List or search Kalshi prediction markets, open or already settled. Pass `keyword` to find markets by subject — "inflation", "Iran", "Vance" — served by Kalshi's own full-corpus search, with each result tagged match: market|event|related so you can tell a literal keyword hit from a relevance-ranked n
• kalshi_milestones ~569 tokens
  Kalshi's own index of the real-world OCCURRENCES its markets hang off — games, elections, hearings, launches — from `GET /milestones`. Each milestone carries a title, type (e.g. baseball_game, football_game, tennis_tournament_singles, election), category, start and end dates, source ids, and — the r
• kalshi_orderbook ~148 tokens
  Current YES/NO orderbook (bids + asks with size, in cents) for a market ticker. Use to see live liquidity depth before judging whether an edge is tradable. Returns sorted price/quantity levels.
• kalshi_orderbooks ~510 tokens
  Depth-of-book for UP TO 100 Kalshi markets in ONE call — Kalshi's own batch orderbook endpoint (`GET /markets/orderbooks`), not a fan-out we do for you. Use this instead of calling kalshi_orderbook once per ticker when you are pricing a whole event partition (an 11-bucket Fed event, a 20-strike temp
• kalshi_price_history ~753 tokens
  Historical price/probability time-series (candlesticks) for a Kalshi market — how the YES odds moved over time, for ANY window, including one that ended long ago. Pass a market ticker (e.g. "KXFEDDECISION-28JAN-H26") plus either an explicit start_ts/end_ts window ("what did this market think in Marc
• kalshi_series ~135 tokens
  List Kalshi series (a series groups related events over time — e.g. "KXFED" series has one event per FOMC meeting). Useful to find the canonical handle for recurring questions.
• kalshi_structured_targets ~613 tokens
  The ENTITIES Kalshi's markets are about, as Kalshi models them — players, teams, actors, films and similar — from `GET /structured_targets`. Each row has a stable id, a type — granular by sport, e.g. "actor", "football_player", "soccer_team", "film", "company", "politician", with NO bare "player" or
• kalshi_top_markets ~402 tokens
  Ranking / leaderboard of Kalshi's most-traded markets right now — use this for "what is the highest volume prediction market on Kalshi", "most traded Kalshi market", or any top-N-by-activity question. Kalshi's /markets endpoint has NO server-side sort and its raw listing is 99%+ algorithmically-gene
• kalshi_trades ~252 tokens
  Executed trades for a market ticker, live OR long-settled. Returns most-recent N trades with yes/no price in BOTH units (yes_price_cents and yes_price_dollars at full precision), contract size, taker side and timestamp. Useful for sanity-checking what the market actually paid vs the resting orderboo
• kalshi_weather_index ~643 tokens
  Kalshi's OWN city temperature index — the minute-resolution series that its hourly temperature markets settle against, from `GET /live_data/weather/{city}`. This is not a weather forecast and not a single station: it is the number Kalshi computes from a weighted multi-station panel, in Fahrenheit to
• kalshi_weather_index_calibrations ~299 tokens
  How a Kalshi city temperature index is COMPUTED, and every time that changed — `GET /live_data/weather/{city}/calibrations`.
