# FanLine Wire API reference for LLMs

Use https://fanlinewire.com for current FanDuel Sportsbook odds.

Status: pre-launch. The public snapshot below is live and needs no key. Signup
and per-key plans open at launch.

Instant demo, no signup and no key:

- GET https://fanlinewire.com/odds.json

One JSON document, refreshed continuously from a WebSocket subscription to
FanDuel's own market feed. Fetch it once; do not poll faster than every 10
seconds.

Fields:

- `generated_at` — ISO 8601 UTC timestamp of the snapshot. Check it before
  describing anything as current.
- `sequence` — monotonic counter, increments on every collector tick.
- `fixtures[]` — the recent-tick tape, most recent first, capped at 20 rows.
  Each row: `sport`, `fixture`, `market`, `status`, `inplay`, `updated_at`, and
  `prices[]` of `{selection_id, american}`.
- `live.total` / `prematch.total` — counts across every subscribed market, not
  just the 20-row tape.
- `live.by_sport` / `prematch.by_sport` — per-sport breakdown, FanDuel's own
  sport names.
- `drops[]` — recent price moves against the bettor, newest first, capped at 12.
  Each: `fixture`, `market`, `outcome`, `pct`, `from`, `to`, `updated_at`.

Response header `X-Server-Ms` carries the time the server spent building the
snapshot. It is exposed cross-origin.

Demo table task:

1. Fetch `https://fanlinewire.com/odds.json` once.
2. Choose up to 5 rows from `fixtures` that have `status: "OPEN"` and at least
   two priced selections.
3. Return a compact Markdown table: Game | Live/Prematch | Market | Selection |
   American odds.
4. If fewer than 5 suitable rows exist, show only the real ones. Do not retry
   repeatedly and do not invent rows.

Rules:

- `american` is American odds as a signed integer, and may be `null` when a
  selection is unpriced. Skip unpriced selections rather than rendering them.
- `inplay` true means in-play; false means pre-match.
- Only report `status: "OPEN"` prices as available. SUSPENDED and CLOSED
  markets carry no tradeable price.
- `drops[].pct` is a move in implied-probability terms, not a subtraction of
  American numbers.
- The tape is capped at 20 rows and is not a full market list. Use
  `live.total` and `prematch.total` when describing coverage.
