A read-only interface for browsing public sports prediction-market events and their contract prices. The prices are cached snapshots that represent market probabilities, not guaranteed trading quotes.

Use it to find games and markets, inspect teams and leagues, and read prices for moneyline, spread, total, and other sports contracts.

It provides sports market information without placing trades or requiring an API key. It also makes the limits of the data clear: there are no live prices, order books, or execution guarantees.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00164	$0.01246
Opus 5.5	$0.00066	$0.00498
Sonnet 5.5	$0.00033	$0.00249
Haiku 4.5	$0.00016	$0.00125

Measured 9d ago against content hash 9b7ef1d6c4d1, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

gemini scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Gemini Predictions — Public Sports Markets (read-only)

Before writing queries, consult references/api-reference.md for parameters, field meanings and caveats.

What this skill returns:

✅ Events (one market each: moneyline, spread, total, ...) with league, sport, status, market_type/market_subject/market_scope, kickoff start_time, participants with home/away sides, and contracts.
✅ Contract prices as 0-1 probabilities: buy_yes, buy_no, sell_yes, sell_no, best_bid, best_ask, last_trade_price. A missing or invalid price is null, never 0.
✅ A game's moneyline event nests its other markets (spreads, totals, props) under child_events; these are separate markets, not equivalent moneylines.
❌ Trading, positions, order books, streaming. Every payload is a cached snapshot (price_basis: "cached_snapshot", execution_guaranteed: false, retrieved_at = original retrieval time).

Quick Start

sports-skills gemini get_events --league=nba --limit=20
sports-skills gemini get_event --event_ticker=NBA-2610232300-MIN-ORL-M
sports-skills gemini search_markets --query="Timberwolves Magic" --league=nba --market_type=moneyline
sports-skills gemini get_todays_events --league=epl

Python SDK:

from sports_skills import gemini

gemini.search_markets(query="Timberwolves Magic", league="nba", market_type="moneyline")
gemini.get_event(event_ticker="NBA-2610232300-MIN-ORL-M")

Commands

Command	Purpose
`get_events`	One page of Sports events (`status` default `active`); pass `next_offset` back as `--offset`
`get_event`	One event by ticker, with contracts and child markets
`search_markets`	Token-AND keyword search over title and participant names across a bounded scan (5 pages of 100); child markets flattened once; `truncated: true` when the scan or `limit` dropped results; a failed later page appears in `warnings`
`get_todays_events`	Events whose `startTime` is today's UTC date (same bounded scan, reports `truncated` and `warnings`)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
