name: kalshi
description: |
  Kalshi prediction markets — events, series, markets, trades, and candlestick data. Public API, no auth required for reads. US-regulated exchange (CFTC). Covers football (EPL, UCL, La Liga), basketball, baseball, tennis, NFL, hockey event contracts.

  Use when: user asks about Kalshi-specific markets, event contracts, CFTC-regulated prediction markets, or candlestick/OHLC price history on sports outcomes.
  Don't use when: user asks about actual match results, scores, or statistics — use the sport-specific skill: football-data (soccer), nfl-data (NFL), nba-data (NBA), wnba-data (WNBA), nhl-data (NHL), mlb-data (MLB), tennis-data (tennis), golf-data (golf), cricket-data (cricket), cfb-data (college football), cbb-data (college basketball), or fastf1 (F1). Don't use for general "who will win" questions unless Kalshi is specifically mentioned — try polymarket first (broader sports coverage). Don't use for news — use sports-news instead.

Kalshi — Prediction Markets

Before writing queries, consult `references/api-reference.md` for sport codes, series tickers, and command parameters.

Quick Start

Prefer the CLI — it avoids Python import path issues:

sports-skills kalshi search_markets --sport=nba
sports-skills kalshi get_todays_events --sport=nba
sports-skills kalshi get_sports_config
sports-skills kalshi get_markets --series_ticker=KXNBA --status=open

Python SDK (alternative):

from sports_skills import kalshi

kalshi.search_markets(sport='nba')
kalshi.search_markets(sport='nba', query='Lakers')
kalshi.get_todays_events(sport='nba')
kalshi.get_sports_config()
kalshi.get_markets(series_ticker="KXNBA", status="open")

CRITICAL: Before Any Query

CRITICAL: Before calling any market endpoint, verify:

• The `sport` parameter is always passed to `search_markets` and `get_todays_events` for single-game markets.
• Prices are on a 0-100 integer scale (20 = 20% implied probability) — do not treat as American odds.
• `status="open"` is used when querying markets to exclude settled/closed markets.

Without the `sport` parameter:

WRONG: search_markets(query="Leeds")           → 0 results
RIGHT: search_markets(sport='epl', query='Leeds') → returns all Leeds markets

Important Notes

• **On Kalshi, "Football" = NFL.** For football/soccer (EPL, La Liga, etc.), use sport codes: `epl`, `ucl`, `laliga`, `bundesliga`, `seriea`, `ligue1`, `mls`, `worldcup`.
• **Prices are probabilities.** A `last_price` of 20 means 20% implied probability. Scale is 0-100 (not 0-1 like Polymarket).
• **Always use `status="open"`** when querying markets, otherwise results include settled/closed markets.
• **Shared interface with Polymarket:** `search_markets(sport=...)`, `get_todays_events(sport=...)`, and `get_sports_config()` work the same way on both platforms.

Workflows

Sport Market Search (Recommended)

1. `search_markets --sport=nba` — finds all open NBA markets. 2. Optionally add `--query="Lakers"` to filter by keyword. 3. Results include yes_bid, no_bid, volume for each market.

Today's Events

1. `get_todays_events --sport=nba` — open events with nested markets. 2. Present events with prices (price = implied probability, 0-100 scale).

Futures Market Check

1. `get_markets --series_ticker=<ticker> --status=open` 2. Sort by `last_price` descending. 3. Present top contenders with probability and volume.

Market Price History

1. Get market ticker from `search_markets --sport=nba`. 2. `get_market_candlesticks --series_ticker=<s> --ticker=<t> --start_ts=<start> --end_ts=<end> --period_interval=60` 3. Present OHLC with volume.

Commands that DO NOT exist — never call these

• ~~`get_odds`~~ — does not exist. Use `search_markets` or `get_markets` to find market prices.
• ~~`get_team_schedule`~~ — does not exist. Kalshi has markets, not schedules. Use the sport-specific skill for schedules.
• ~~`get_scores`~~ / ~~`get_results`~~ — does not exist. Kalshi is a prediction market. Use the sport-specific skill.
