All data is collected via Sportradar’s expert operators. Select the **IndyCar** package in our [Coverage Matrix](https://coverage-matrix.sportradar.com) for events and data offered. This API uses a descending, stage-based structure. By changing the stage ID, you can retrieve information on a season, event, race, or any of the practice or qualifying stages. Additional feeds provide complementary stats, including racer profiles and race win probabilities. ### Authentication is required for all API calls.
*** ## Stage Format The core of this API is built around the concept of stages. For example, an event may contain the following stage types: practice, qualifying, and race. Each of those stages, in turn, have stages. The IDs of each stage are usable in the [Stage Summary](https://developer.sportradar.com/racing/reference/indycar-stage-summary) path to request information about that particular stage. See the below [Stage Types](https://developer.sportradar.com/racing/reference/indycar-overview#stage-types) table for all available stage types, their sub-stages, and their definitions. The best way to start the navigation with the IndyCar API is the [Seasons](https://developer.sportradar.com/racing/reference/indycar-seasons) endpoint. From there, obtain the stage ID for the season required and use that in the [Stage Summary](https://developer.sportradar.com/racing/reference/indycar-stage-summary) as a starting point into the sub-stages.
### Stage Types

`} *** ### Endpoint Descriptions **Competitor Merge Mappings** - Provides the valid Sportradar Id in cases when two competitors have been merged into one. **Competitor Profile** – Provides biographical information for a given driver.  **Deleted Stages** - Provides all deleted stages within a given season. **Seasons** - Provides a complete historical list of available seasons. This is the starting point for the IndyCar API.  **Stage Probabilities** – Provides the outrights for each driver for a given race.  **Stage Schedule** – Provides schedule information for a given stage.  **Stage Summary** – Provides schedules and results information based on the stage provided (season, event, practice, qualifying, qualifying part, or race). *** ### Data Retrieval Sample To find the win probabilities for a given race:
  1. Call the Seasons endpoint and find the Stage Id for the current season
  2. Call the Stage Schedule using the 'season' Stage Id
  3. Locate the Stage Id for the upcoming race
  4. Call the Stage Probabilities using the 'race' Stage Id
  5. Within the results locate the win probability for each racer
The probability of a win for each racer is displayed.
