Summary field

fairOdds — No-vig price: implied probabilities from all books are averaged, then normalized so the binary pair sums to 1.0, then converted back to American odds.
bestOdds — The highest American odds offered by any single bookmaker for that outcome.
avgOdds — Simple average of implied probabilities across all books, converted to American odds.
Summary is computed from the full bookmaker set returned for the event.

Odds History

Track how a line has moved over time. Each snapshot is a consensus row per (marketType, player, outcome, point) with the cross-book average, best, and no-vig fair price at that moment. Game markets and player props are both included. Consensus covers sportsbooks and exchanges; DFS is excluded because its prices are indicative, not tradeable.

Snapshots are written on a tiered cadence based on time-to-game so storage and payload sizes stay small:

More than 7 days out → every 24 hours
24 hours to 7 days out → every 12 hours
3 to 24 hours out → every 60 minutes
Less than 3 hours out → every 20 minutes

The first snapshot for an event is written the first time the API fetches odds for it (typically within ~10 minutes of a new event being seeded). History for an event is automatically deleted shortly after the game goes final.

GET/v1/events/:eventId/odds-history

Consensus line-movement history for a specific event, sorted ascending by snapshot time so the first entry is the opening line captured and the last is the most recent.

Parameter	Type	Required	Description
eventId	string	Yes	The event identifier
market	string	No	Optional exact market filter (e.g. moneyline, spread, total, player_points)
playerId	string	No	Optional canonical player ID — returns only rows belonging to that player within the event
from	string	No	Optional ISO 8601 timestamp lower bound on snapshotAt
to	string	No	Optional ISO 8601 timestamp upper bound on snapshotAt
limit	number	No	Max snapshots returned. Default 500, max 2000
