Overview

The primary per-venue discovery endpoint for sports markets. Returns a paginated list of games, each containing every venue that lists that game, nested with the venue’s native market metadata and canonical outcomes. Responses are grouped per the structure described on the Sports Markets concept page:

games[]
  └── market_types[]
       └── venues[]
            └── outcomes[] with event_id and canonical predexon_id

Query Parameters

Param	Type	Default	Description
`sport`	string	-	Filter by sport. Must be one of `basketball`, `soccer`, `hockey`, `baseball`.
`league`	string	-	Filter by league code. See coverage matrix for valid values.
`status`	string	`open`	`open` (currently tradeable) or `closed` (resolved or past-dated).
`game_date`	string	-	Exact game date, `YYYY-MM-DD`. Dates follow the sport’s timezone convention — see note below.
`game_date_from`	string	-	Inclusive lower bound, `YYYY-MM-DD`.
`game_date_to`	string	-	Inclusive upper bound, `YYYY-MM-DD`.
`venue`	string	-	Only return games that include the given venue. One of `polymarket`, `kalshi`, `limitless`, `opinion`, `predict`.
`search`	string	-	Case-insensitive substring search against venue-level `market_title`.
`sort_by`	string	`game_date_asc`	`game_date_asc` (soonest first) or `game_date_desc` (latest first).
`limit`	int	`50`	1-200.
`pagination_key`	string	-	Opaque cursor from the previous response. Omit on the first request.

Pagination

Sports list endpoints use cursor pagination. Pass the returned pagination.pagination_key into the next request. Do not use offset-based pagination.

Filter Semantics

Date timezone convention: game_date, game_date_from, and game_date_to follow the sport’s local convention. US sports (NBA, NHL, MLB, NFL, CFB, MLS) use Eastern Time dates. European football (EPL, La Liga, etc.) uses UTC dates. Each game in the response includes a game_date_timezone field ("US/Eastern" or "UTC") so you can interpret dates programmatically.
status=open filters out games whose game_date is in the past. Games from yesterday are included to account for late-night US games (an NBA game at 10:30 PM ET has a game_date in ET but may not end until after midnight UTC). Once the upstream venue reports the market as closed, the game status flips to closed regardless of date.
status=closed returns explicitly closed games and any past-dated games.
When both game_date_from and game_date_to are provided, from must be <= to (400 otherwise).
Invalid enum values for sport, status, venue, or sort_by return 400 Bad Request with a descriptive error.
Invalid date formats return 400 Bad Request.

Response Fields

Top level

Field	Type	Description
`games[]`	array	Games matching the filter.
`pagination.limit`	int	Echoes the request limit.
`pagination.has_more`	boolean	Whether another page is available.
`pagination.pagination_key`	string?	Cursor for the next page. `null` when `has_more=false`.

Game

Field	Type	Description
`game_id`	string	Canonical game identifier, e.g. `nba-atl-nyk-2026-04-18`.
`league`	string	League code, e.g. `nba`.
`league_name`	string	Human-readable league name, e.g. `"NBA"`.
`sport`	string	Sport name, e.g. `"basketball"`.
`game_date`	string	Calendar date of the game, `YYYY-MM-DD`. See date semantics.
`game_date_timezone`	string	Timezone convention for `game_date`: `"US/Eastern"` (US sports) or `"UTC"` (European football).
`title`	string	Canonical display title, e.g. `"Atlanta Hawks vs New York Knicks"`.
`status`	string	`"open"` or `"closed"`.
`market_types[]`	array	Types of markets available for this game (e.g. `game_winner`).

market_type entry

Field	Type	Description
`market_type`	string	Canonical market type identifier. Currently always `"game_winner"`.
`venues[]`	array	One entry per venue that lists this market type for this game.
`event_id`	string	Canonical market/question identifier for this market type. In sports v1 this usually equals `game_id`.

Venue Block

Field	Type	Description
`venue`	string	`"polymarket"`, `"kalshi"`, `"limitless"`, `"opinion"`, or `"predict"`.
`market_title`	string	Venue’s native market title.
`volume`	number?	USD traded volume. `null` when the venue doesn’t expose volume. For 3-way markets this is the sum across all underlying child markets.
`liquidity`	number?	USD liquidity. `null` for venues that don’t expose liquidity.
`end_time`	string?	ISO-8601 UTC timestamp of market close (e.g. `"2026-04-18T22:00:00+00:00"`). `null` for venues without an indexed close time.
`outcomes[]`	array	Tradeable sides of this market on this venue.

Outcome

Each outcome represents one venue question/selection (e.g. “Mallorca wins”). tokens.yes and tokens.no are both included when the venue exposes executable sides for that exact selection.

Field	Type	Description
`outcome`	string	Canonical outcome code - either a team code (`"atl"`, `"mal"`) or `"draw"`. Same across venues.
`outcome_label`	string	Human-readable label, e.g. `"Atlanta Hawks"`, `"Mallorca"`.
`event_id`	string	Canonical market/question identifier.
`condition_id`	string?	On-chain CTF `conditionId` for this specific outcome’s market. Present for Polymarket, Limitless, Predict. Each outcome in a 3-way game has its own `condition_id`.
`market_slug`	string?	Venue-native slug for this outcome’s market.
`market_id`	string?	Venue-native non-condition identifier. Present for Kalshi (ticker) and Opinion (integer).
`tokens`	object	Tradeable side entries with prices and identifiers.
`tokens.yes.price`	number?	YES-side price (0.0 - 1.0). Cost to bet FOR this outcome. `null` if unpriced.
`tokens.yes.token_id`	string?	Venue-native token ID. Present for on-chain venues (Polymarket, Limitless, Predict, Opinion). Not present for Kalshi.
`tokens.yes.predexon_id`	string	Canonical Predexon outcome ID. Same outcome across venues shares this ID.
`tokens.no.price`	number?	NO-side price (0.0 - 1.0). Cost to bet AGAINST this outcome.
`tokens.no.token_id`	string?	Venue-native token ID. Same presence rules as YES.
`tokens.no.predexon_id`	string?	Canonical Predexon ID for buying NO on that exact venue question/selection when exposed. In 2-way games this may equal the sibling YES outcome ID; in 3-way soccer it points to an explicit negation outcome such as “Draw does not happen.”

EPL game - 3-way (Limitless)

Each outcome has its own condition_id and market_slug because on-chain venues create a separate binary market per outcome.

For 3-way football on Polymarket, Limitless, and Predict.fun, each outcome is a separate on-chain market natively. Predexon aggregates them into a single venue block and sums the volume/liquidity across the constituent markets. Each outcome retains its own condition_id and market_slug.
