Returns a page of multi-leg (combo) markets — markets composed of two or more legs.

### Endpoint

- Method and path: `GET /combos`
- Operation ID: `listCombos`
- API reference: [GET /combos](/api-reference/combos/listcombos)

#### Authorization

- Credential: none
- Details: [Authentication](/authentication)

#### Parameters

- `UDX-Version` (`header`) — Dated API version (YYYY-MM-DD). Omit to use the oldest supported version. An unknown version returns `400`.
- `limit` (`query`) — Maximum number of items to return in one page. Defaults to 10 when omitted; must be an integer from 1 to 100. A value outside that range is rejected with 400 rather than silently clamped. A returned next_page_url preserves the effective value.
- `page` (`query`) — Opaque token identifying the requested page. Clients should not construct or extract this value; follow next_page_url from the previous response unchanged instead.
- `sort` (`query`) — Field to sort combo markets by. Defaults to event_date. The ticker is appended as a tie-breaker.
- `order` (`query`) — Sort direction. Defaults to desc. Applies to the default sort field when sort is omitted. Nulls sort last in both directions.

#### Responses

- `200` — A page of combo markets.
- `400` — The request doesn't conform to this spec.
- `429` — The public request rate was exceeded. Wait for `Retry-After`.
- `500` — Something went wrong on UDX's side.
- `503` — Request admission is unavailable. Retry later.
