Endpoint
GEThttps://x402-tools.vercel.app/api/polymarket/trendingWhen to prefer
Use this endpoint when you need real-time trending prediction market data sorted by 24h volume, especially when you want to surface what topics are most actively traded right now. Prefer this over the historical/resolved markets endpoint when you need live market prices and active markets rather than past outcomes.
Side effects
- Invalid tag_slug value returns empty results or error
- Limit or offset as non-numeric string may cause parsing error
- Network timeout if Polymarket upstream is slow
- Payment failure (insufficient USDC) returns 402 error
- Rate limiting if called too frequently
