Data Model

The V2 API organizes sports data in a nested hierarchy. Understanding this structure is essential for parsing event responses, building odds screens, and processing delta updates.

Hierarchy Overview

Event Object

Each event represents a single game or match. Events are the top-level objects returned by /api/v2/sports/{sportID}/events/{date}.

Field	Type	Description
`event_id`	string	Canonical event identifier string. Use this value in V2 path params, filters, delta consumers, and cache keys.
`sport_id`	integer	Sport identifier. See Sport IDs.
`event_uuid`	string	Compatibility identifier retained for older integrations. Do not assume it matches `event_id`.
`event_date`	string	Scheduled start time in ISO 8601 UTC
`rotation_number_away`	integer	Away team rotation number (not used for soccer)
`rotation_number_home`	integer	Home team rotation number (not used for soccer)
`score`	object	Live score and game status. See Score Object below.
`teams`	array	Two-element array: `[away_team, home_team]`. See Team Object below.
`schedule`	object	Season metadata: `season_type`, `season_year`, `event_name`, `league_name`
`markets`	array	Array of Market objects with odds data

For V2 REST endpoints and WebSocket filters, pass the event_id value returned in event payloads. Do not substitute event_uuid.

Score Object

Field	Type	Description
`event_status`	string	Current status (e.g., `STATUS_SCHEDULED`, `STATUS_IN_PROGRESS`, `STATUS_FINAL`). See Event Statuses.
`score_away`	integer	Away team score
`score_home`	integer	Home team score
`score_away_by_period`	array	Score breakdown by period
`score_home_by_period`	array	Score breakdown by period
`venue_name`	string	Arena or stadium name. May be an empty string when unavailable from the live feed.
`venue_location`	string	City and state. May be an empty string when unavailable from the live feed.
`game_clock`	integer	Game clock in seconds
`display_clock`	string	Formatted clock display (e.g., “4:32”)
`game_period`	integer	Current period number
`broadcast`	string	TV broadcast network
`event_status_detail`	string	Human-readable status (e.g., “3rd Quarter - 4:32”)
`updated_at`	string	ISO 8601 timestamp of the last score update

Treat score as best-effort live feed data. Fields such as venue_name, venue_location, broadcast, display_clock, and the period arrays may be empty strings, empty arrays, or 0 until the upstream source provides them. Use updated_at to judge freshness.

Team Object

Field	Type	Description
`team_id`	integer	Normalized team identifier (stable across seasons and endpoints)
`name`	string	Full team name (e.g., “Cleveland Cavaliers”)
`mascot`	string	Team mascot (e.g., “Cavaliers”)
`abbreviation`	string	Short abbreviation (e.g., “CLE”)
`record`	string	Current season record (e.g., “42-14”)
`is_away`	boolean	`true` if this is the away team
`is_home`	boolean	`true` if this is the home team

Market Object

Each market represents a type of bet (moneyline, spread, total, player prop, etc.). Markets are nested inside events.

Field	Type	Description
`id`	integer	Instance identifier for this market on this event
`market_id`	integer	Canonical market type ID. See Market IDs.
`period_id`	integer	Period this market applies to. `0` = full game. See Period IDs.
`name`	string	Display name (e.g., “Moneyline”, “Total Over/Under”)
`market_description`	string	Human-readable description
`participants`	array	Array of Participant objects

Participant Object

Participants are the entities you can bet on within a market — teams, players, or result types (Over/Under).

Field	Type	Description
`id`	integer	Participant identifier (team ID, player ID, or `0`/`1` for result types)
`type`	string	`TYPE_TEAM`, `TYPE_PLAYER`, or `TYPE_RESULT`
`name`	string	Display name (e.g., “Cleveland Cavaliers”, “Donovan Mitchell”, “Over”)
`lines`	array	Array of Line objects

id is the stable, joinable identifier — join on id, not name. What id points to depends on type:

TYPE_TEAM — id is the normalized team ID. It is stable across seasons and endpoints, and matches event.teams[].team_id. Fetch the full team at GET /api/v2/teams/{team_id}.
TYPE_PLAYER — id is the player ID. Fetch the full player (team, names, position) at GET /api/v2/players/{player_id}.
TYPE_RESULT — id is a small outcome index (e.g. 0/1 for Over/Under) and is not a team or player resource key.

Because every distinct team and player has a distinct id, joining on id resolves shared-name collisions that joining on name cannot. To look up an id from a name once, use the roster at GET /api/v2/teams/{team_id}/players or the team list at GET /api/v2/sports/{sportID}/teams.

Line Object

A line represents a specific betting line for a participant. For spreads and totals, the value contains the line number. For moneylines, value is an empty string.

Field	Type	Description
`id`	string	32-character hex identifier for this line
`value`	string	Line value: `"-3.5"` for spread, `"224.5"` for total, `""` for moneyline
`prices`	object	Map of affiliate ID → Price object. Keyed by sportsbook.

line_value_is_participant tells you where the meaningful selection detail lives. When it is true, the participant carries the selection and the line value may be a placeholder or label. When it is false, display the line value when present; it may be a number, threshold, method, round, or other outcome qualifier.

Price Object

A price is the odds offered by a single sportsbook for a specific line.

Field	Type	Description
`id`	string	Numeric string identifier for this price
`price`	number	American odds (e.g., `-110`, `+150`). A value of `0.0001` means the line is off the board. See Sentinel Values.
`is_main_line`	boolean	`true` if this is the primary/consensus line. Use `main_line=true` query param to filter to main lines only.
`updated_at`	string	ISO 8601 timestamp of the last price update

Fields that appear in delta/history responses:

Field	Type	Description
`price_delta`	number	Difference from the previous price (present in some delta responses)
`closed_at`	string	ISO 8601 timestamp when the line was closed. Empty string if still active.

Traversing the Data

Reading a moneyline price

event.markets[0].participants[0].lines[0].prices["19"].price

Gives you the DraftKings (affiliate 19) moneyline price for the first participant (away team).

Reading a spread value and price

event.markets[1].participants[0].lines[0].value    → "-3.5"
event.markets[1].participants[0].lines[0].prices["19"].price → -110

Iterating all prices for an event

for market in event["markets"]:
    for participant in market["participants"]:
        for line in participant["lines"]:
            for affiliate_id, price_obj in line["prices"].items():
                print(f"{market['name']} | {participant['name']} | "
                      f"{line['value']} | {affiliate_id}: {price_obj['price']}")

Delta Responses

Delta endpoints return a different shape. Instead of the nested event → market → participant → line → price hierarchy, they return flat change records:

Field	Description
`event_id`	Which event changed
`market_id`	Which market
`participant_id`	Which participant
`affiliate_id`	Which sportsbook
`line`	Line value
`price`	New price
`previous_price`	Previous price (empty string if new)
`change_type`	`"new"`, `"price_change"`, or `"line_change"`

Use the event_id, market_id, participant_id, and affiliate_id to locate the correct entry in your local cache and replace the price. See the Efficient Polling guide for the full update pattern.
