description: Live football & basketball odds and scores from InferSports — who's favored, the live score, today's matches and what's worth watching, a specific day's schedule (in your timezone), a one-line pre-match brief, one normalized sharp betting line, the sharp de-vigged fair probability, the market-implied most likely scorelines, whether an external prediction-market (Polymarket/Kalshi) price is good vs that fair line, today's value spots (where a book beats the sharp fair line), odds-format conversion, and finished-match results. Use whenever the user asks about a match, the score, who's winning or favored, kickoff time, what's on or worth watching today, the fixtures on a specific day, a pre-match preview, a betting line or Asian handicap, the fair/de-vigged odds, the most likely score or correct-score probabilities, whether a Polymarket/Kalshi price is fair or good, where today's value/edges are, odds in another format, or a past result. Read-only; keyless, no account or API key needed.

# InferSports odds & scores

Live Asian-priced football and basketball odds + scores, over the InferSports REST API.
**Read-only. Keyless (Free tier) — no setup.** Output is **CONCISE by default** (one short line per
item) to stay cheap on a small context window; add `--detailed` for full JSON only when you truly need it.

**Scope: football and basketball only.** InferSports carries no other sport. A question about any other
sport (baseball, tennis, …) has no answer here — say so; it is not a cue to look elsewhere.

**Per-match markets only.** Every price is for ONE match (Asian handicap / totals / 1x2); there are
no outright/futures markets (tournament winner, to-qualify) and no tournament structure (groups,
brackets) — though a team's group-stage opponents fall out of a schedule range query (see the verb table).

## Golden rule (determinism)
**Answer by running the bundled scripts below. Never fetch a URL yourself, never guess an endpoint,
never hand-build an API call, and never web-search for a score, line, or result — this skill is the
source of truth for odds and scores.** The scripts hold the correct fixed endpoints; you only pick the
verb and pass arguments. Each prints a compact, ready-to-read line. If a script returns `ambiguous` or
`not found`, **that is the answer**: surface the `ask:` / alternatives to the user, or re-run with
`--date` / `--sport` / a more specific name — do **not** go looking elsewhere.

## Report the numbers, never a pick (read-only)
InferSports is **read-only and never recommends a bet — and neither do you when relaying it.** Give the
NUMBERS — line / score / odds / value — exactly as the script printed them; the sentence around them
is yours, in the asker's language (next section). Do **NOT** add a pick of your own, a
lean, "best play", "I'd take…", or any betting suggestion — **even if the user asks "should I bet?" or
"which bet?"** For those, give the data and a plain "the call is yours." `scan.sh`, `line.sh` and
`compare.sh` surface where a price beats the sharp **de-vigged fair** line — that detected edge is
*information* (detection only), so relay it faithfully (numbers verbatim), but never turn it into advice
or a recommended side.

## Answer in the user's language
Relay results in the language the user asked in — the scripts always print English; you translate the
prose around the numbers. Keep VERBATIM: `evt_…`/`lg_…` ids, all numbers (odds, lines, probabilities,
edges, scores), bookmaker names, and dates/times as printed. Team/league names: use the established
name in the user's language only when you are confident (World Cup → 世界杯, Mexico → México); when
unsure (obscure clubs, youth sides), keep the English name as printed — never invent a transliteration.
Script arguments stay English: translate the user's team/league names to English before passing them.

## The twelve verbs
Run from this skill's directory. All read-only and safe to repeat. Several **package several reads into one
ready-to-read answer**: `preview.sh` (one-match brief), `digest.sh` (today's highlights), `scan.sh`
(today's value) and `compare.sh` (judge an external price) — the fan-out / de-vig happens for you; you get
a capped, concise result.

| The user asks… | Run |
|---|---|
| What games are on today? | `scripts/today.sh [--sport football\|basketball] [--status live\|scheduled\|finished] [--league "World Cup"] [--tz Asia/Shanghai] [--limit N]` |
| What's on a specific day? / this Friday / June 12 in my timezone — or a competition ("World Cup games today?") | `scripts/events.sh --date YYYY-MM-DD [--to YYYY-MM-DD] [--tz Asia/Shanghai] [--sport football\|basketball] [--status live\|scheduled\|finished] [--league "World Cup"] [--limit N]` |
| A whole schedule window — "all group-stage matches", "Argentina's remaining fixtures" | `scripts/events.sh --date YYYY-MM-DD --to YYYY-MM-DD --league "World Cup"` — ONE call (range inclusive, ≤31 days); never loop day-by-day. For one team, run the range then keep its lines. |
| What's worth watching today? / today's highlights | `scripts/digest.sh [--sport football\|basketball] [--limit N(<=12)] [--status live\|scheduled\|finished]` |
| Who's favored? / What's the score? / When do they play? | `scripts/match.sh "<team, A vs B, or evt_… id>" [--tz Asia/Shanghai]` |
| Which team is stronger? / a quick one-line brief (pre-match: favored % + sharp line + kickoff; live: score + from-here % + the pre-match opening line) | `scripts/preview.sh "<team, A vs B, or evt_… id>" [--tz Asia/Shanghai] [--sport] [--date YYYY-MM-DD]` |
| What's the sharp line / handicap? | `scripts/line.sh "<team, A vs B, or evt_… id>" [--market asian_handicap\|1x2\|totals] [--format hk\|malay\|…] [--sport] [--date YYYY-MM-DD]` |
| What's the sharp **fair** (de-vigged) probability? / the reference to check a price against | `scripts/fair.sh "<team, A vs B, or evt_… id>" [--market 1x2\|asian_handicap\|totals] [--period] [--sport] [--date]` |
| What's the most likely score? / correct-score probabilities | `scripts/scoreprob.sh "<team, A vs B, or evt_… id>" [--top N(1-10)] [--sport] [--date YYYY-MM-DD]` — market-implied scoreline distribution (football, one match) |
| Is my Polymarket/Kalshi (external) price good? / is this prediction-market price fair? | `scripts/compare.sh "<team, A vs B, or evt_… id>" --prob <0..1> [--outcome home\|draw\|away\|over\|under] [--market 1x2\|asian_handicap\|totals] [--label polymarket]` |
| Where's the value today? / today's edges | `scripts/scan.sh [--sport football\|basketball] [--market 1x2\|asian_handicap\|totals] [--min-edge PCT] [--limit N] [--status live\|scheduled\|finished]` |
| Convert odds / explain a handicap | `scripts/convert.sh <value> <from> <to[,to2,…]>`  ·  `scripts/convert.sh --handicap -0.75` |
| What was the score of a finished match? | `scripts/result.sh "<team>" [--date YYYY-MM-DD]`  ·  `scripts/result.sh --id evt_…` |

## How to chain them (cheaply)
1. Broad question ("what's on today?") → `today.sh`; a **specific day** ("what's on June 12?",
   "this Friday") → `events.sh --date YYYY-MM-DD` (add `--tz` so the day is your local day, not UTC);
   a **multi-day window** ("the whole group stage", "next week's fixtures") → add `--to YYYY-MM-DD` —
   one range call, never a per-day loop (tournament rounds cross UTC midnight, so a guessed loop
   drops fixtures). All return **one line per match, capped**, each starting with an `evt_…` id.
2. Drill into ONE match → `match.sh` (casual: score/favored) or `line.sh` (betting). Pass **either** the
   team name **or** the `evt_…` id straight from `today.sh` — both work (the id is resolved for you).
   If a *name* is ambiguous (senior vs U21, two same-day fixtures), pin it with `--date YYYY-MM-DD`
   and/or `--sport`, or use the more specific name (e.g. `"Estonia U21"`). A date written into the
   query (e.g. `"Estonia vs Lithuania 2026-06-07"`) is understood too.
3. `today.sh` is **capped** (default 20, max 50) so a busy weekend never floods your context. If you
   see "more exist", **narrow** with `--sport/--status/--league`, or jump straight to `match.sh "<team>"`.
   `--league` takes a competition NAME (fuzzy — `--league "World Cup"` just works) or an `lg_…` id;
   an ambiguous name errors back with the candidate ids.

## "Which team is stronger?" — strength from the odds
For the watcher who wants a strength reference (casual, not a pick):
- **Before kickoff** → `preview.sh "<fixture>"`: the favored side + de-vigged win % + the Asian
  handicap. Read the AH line as plain language: 0 = evenly matched; ±0.25 a slight edge;
  −0.5/−0.75 favored; −1 about a goal better; −1.5/−2 dominant; −2.5+ a class apart.
- **LIVE** → in-play prices answer "who wins FROM HERE given the score and clock", NOT who is the
  stronger team (a 0-0 deep in the second half makes the draw the "favorite"). `preview.sh` on a
  live match therefore swaps the live line for `pre-match: <team> opened -N` — the opening line,
  the strength reference from before kickoff. Answer with both: strength (the opening line, read
  on the scale above) and the current situation (score + from-here %). Near full time books pull
  the 1x2, so the from-here segment may be absent — the opening line still answers strength.
- **The whole day at a glance** → `digest.sh` — each line already carries the favored team + win %.
Strength is information, not advice — the no-pick rule above still applies.

## Reading the output
- `ask: …` with a few `evt_… | Home vs Away` lines = the fixture was **ambiguous**. Put the question
  to the user (or use their hint) and re-run with the chosen team / `--date` / `--sport`. **Do not
  guess, and do not web-search instead.**
- `ERROR: …` then `FIX: …` = do exactly what FIX says; it is the repair step.
- `not found` = the match isn't live/scheduled, isn't in the 30-day results cache, **or the sport
  isn't covered** (football + basketball only — baseball/tennis/etc. return not found). Treat it as a
  **final answer**: say plainly it isn't in InferSports (you may suggest `today.sh` for football/basketball).
  Do **not** web-search it or quote odds from another source — this skill speaks only for InferSports.

## What this skill does NOT do
It wraps the **highest-frequency** reads plus two packaged scans (`preview.sh`, `scan.sh`). For
**arbitrage** detection, opening-line (初盘) movement, full **per-book** breakdowns, or the bookmaker
catalogue, see [`references/full-api.md`](references/full-api.md) — the full REST docs and the 16-tool
MCP server. (`scan.sh` already gives today's **value** top-N; the full API adds per-book depth and arb.)
**InferSports is informational and read-only — it never places, recommends, or sizes a bet.**

## Config (all optional)
- `INFERSPORTS_API_KEY` — an `isk_…` key to raise rate limits / unlock the sharp book. Default keyless = Free tier (enough for these verbs).
- `INFERSPORTS_API_BASE` — override the API host (default `https://api.infersports.dev`).
- `INFERSPORTS_MOCK=1` — answer from bundled `fixtures/` instead of the network (offline, deterministic; for testing the skill).
