Description

Get the list of categories used to group non-sport prediction market canonical events. Categories are how canonical events are organized (for example politics, finance, crypto, culture), and a category value is required when listing canonical event IDs.

These endpoints cover non-sport prediction markets only (elections, economic indicators, crypto price levels, cultural outcomes, and similar). Sports markets are not returned here — use the sports fixtures and odds endpoints for those.

Note: the full set of categories is always returned, but a category may currently contain zero events depending on what is listed across platforms.

Specific Parameter Information

This endpoint takes no query parameters. Authenticate with the X-Api-Key header.
