# pipeworx `kalshi` — Kalshi

## Coverage
US-regulated prediction-market data — Fed rates, elections, climate, sports, science. Public APIs, no auth. Pairs with the polymarket pack for cross-market spread arb.

Catalog `tool_count`: 19. Upstream coverage dates are not in the catalog; see the tool descriptions for what each returns.

## Access
MCP endpoint `https://gateway.pipeworx.io/kalshi/mcp` — JSON-RPC `tools/list` and `tools/call` over POST, SSE-framed response (`event: message`, one `data:` line; the answer is in `result.structuredContent`). `tools/list` on 2026-10-01 returned 55 tools: these 19 plus the 36 platform tools every pack endpoint lists.

Tools (names and first sentence of each description as served on 2026-10-01):

- `kalshi_markets` — List or search Kalshi prediction markets, open or already settled. No required arguments.
- `kalshi_market` — 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… Required: `ticker`.
- `kalshi_events` — 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). No required arguments.
- `kalshi_event` — AUTHORITATIVE odds from Kalshi — the only CFTC-regulated US prediction-market exchange (US persons CAN legally trade here, unlike Polymarket). Required: `event_ticker`.
- `kalshi_series` — List Kalshi series (a series groups related events over time — e.g. "KXFED" series has one event per FOMC meeting). No required arguments.
- `kalshi_orderbook` — Current YES/NO orderbook (bids + asks with size, in cents) for a market ticker. Required: `ticker`.
- `kalshi_trades` — Executed trades for a market ticker, live OR long-settled. Required: `ticker`.
- `kalshi_price_history` — 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. No required arguments.
- `kalshi_exchange_status` — Exchange-level status: is the trading floor open, are deposits/withdrawals enabled, any scheduled maintenance. No required arguments.
- `kalshi_top_markets` — 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. No required arguments.
- `kalshi_macro` — 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),… Required: `topic`.
- `kalshi_orderbooks` — 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. Required: `tickers`.
- `kalshi_candlesticks` — 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`). Required: `tickers`.
- `kalshi_event_live_data` — The REAL-WORLD measurement an event settles against, next to the odds — Kalshi's event live-data feed (`GET /live_data/events/{event_ticker}`). Required: `event_ticker`.
- `kalshi_game_stats` — 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`. Required: `milestone_id`.
- `kalshi_milestones` — Kalshi's own index of the real-world OCCURRENCES its markets hang off — games, elections, hearings, launches — from `GET /milestones`. No required arguments.
- `kalshi_structured_targets` — The ENTITIES Kalshi's markets are about, as Kalshi models them — players, teams, actors, films and similar — from `GET /structured_targets`. No required arguments.
- `kalshi_weather_index` — Kalshi's OWN city temperature index — the minute-resolution series that its hourly temperature markets settle against, from `GET /live_data/weather/{city}`. Required: `city`.
- `kalshi_weather_index_calibrations` — How a Kalshi city temperature index is COMPUTED, and every time that changed — `GET /live_data/weather/{city}/calibrations`. Required: `city`.

Client setup: `claude mcp add pipeworx-kalshi -- npx -y mcp-remote https://gateway.pipeworx.io/kalshi/mcp`.

## Auth
Catalog `auth.shape`: `keyless`. Verbatim detail: "No key required — open upstream, callable as-is." No credential is needed at the gateway to list or call (anonymous tier; see the gateway record).

## Rate limits
Gateway anonymous tier: 50 calls per day per IP, reset 00:00 UTC, printed in `x-ratelimit-*` headers (observed 2026-10-01 on the fred and weather packs; this pack was listed, not called). Upstream limits are not stated in the catalog.

## Freshness
Not stated in the catalog. Reliability: not measured — catalog says treat as unknown, not good.

## Known gaps
- Cost per call as quoted: 50 credits ($0.0050), category `gov`, basis `list`.
- No catalog notes on cost or licence.
- This record is the catalog's description plus one `tools/list`; it is not a test of the upstream data. Reuse it to find the tool, then observe the upstream yourself.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
