Polymarket Market Details (by Market Slug)

omnial/prediction-market-polymarket-markets

Given a single Polymarket market slug, returns that market's title, description, category/tags, Yes/No outcome token ids, status, and trading volume (1-week, 1-month, 1-year, and all-time). An unrecognized market slug returns an empty result rather than an error.
