Get all markets

Fetch all prediction markets with a single GET request. Use the base URL, endpoint, and optional query parameters to list and sort markets.

Base URL

All API requests use this base:

https://nqyocjuqubsdrguazcjz.supabase.co

HTTP request

To get all markets, send a GET request to the markets endpoint with the required headers. You can add query parameters to sort or limit results.

Endpoint

GET https://nqyocjuqubsdrguazcjz.supabase.co/rest/v1/combined_markets_x_posts

Required headers

apikey: <your-api-key>
Accept: application/json

Developers need to reach out to the team to get their API key. Include the apikey header with that value on every request.

Query parameters (optional)

Control sort order and limit (e.g. order=market_volume.desc, limit=20). To filter by status, see Get markets by status.

Example — all markets, sorted by volume:

GET https://nqyocjuqubsdrguazcjz.supabase.co/rest/v1/combined_markets_x_posts?order=market_volume.desc
