# Polymarket Markets

`GET /gateway/v1/prediction-market/polymarket/markets`

## Request

- URL: `https://api.asksurf.ai/gateway/v1/prediction-market/polymarket/markets`

Returns Polymarket markets, optionally filtered by `market_slug`.

Each market includes `side_a` and `side_b` outcomes. Current prices are available via `/polymarket/prices` using the `condition_id`.

## Query parameters

- `market_slug` string, required: Polymarket market slug (identifies a single Yes/No outcome). Discover slugs via /v1/search/prediction-market?platform=polymarket&q={keyword}. For a multi-outcome question (e.g. 'who wins the 2024 election'), use the /polymarket/events endpoint with event_slug instead.
