3. Fetch All Active Markets

Use Case: When you need to retrieve all available active markets, typically for broader analysis or market discovery.

The most efficient approach is to use the /events endpoint and work backwards, as events contain their associated markets.

Events Endpoint: GET /events

Markets Endpoint: GET /markets

Key Parameters

• order=id - Order by event ID
• ascending=false - Get newest events first
• closed=false - Only active markets
• limit - Control response size
• offset - For pagination

Examples

curl "https://gamma-api.polymarket.com/events?order=id&ascending=false&closed=false&limit=100"

This approach gives you all active markets ordered from newest to oldest, allowing you to systematically process all available trading opportunities.

Pagination

For large datasets, use pagination with limit and offset parameters:

• limit=50 - Return 50 results per page
• offset=0 - Start from the beginning (increment by limit for subsequent pages)

Pagination Examples:

# Page 1: First 50 results (offset=0)
curl "https://gamma-api.polymarket.com/events?order=id&ascending=false&closed=false&limit=50&offset=0"

# Page 2: Next 50 results (offset=50)
curl "https://gamma-api.polymarket.com/events?order=id&ascending=false&closed=false&limit=50&offset=50"

# Page 3: Next 50 results (offset=100)
curl "https://gamma-api.polymarket.com/events?order=id&ascending=false&closed=false&limit=50&offset=100"

# Paginating through markets with tag filtering
curl "https://gamma-api.polymarket.com/markets?tag_id=100381&closed=false&limit=25&offset=0"

# Next page of markets with tag filtering
curl "https://gamma-api.polymarket.com/markets?tag_id=100381&closed=false&limit=25&offset=25"
