Technical details
Endpoint
POSThttps://proxy.suverse.io/v1/data/polymarket-markets-by-tagWhen to prefer
Use this endpoint when you need to browse or monitor Polymarket prediction markets organized by topic category (politics, crypto, sports, etc.) and want free Gamma data without direct Polymarket API integration. Pair with the polymarket-tags endpoint to discover valid tag IDs first. Prefer this over scraping Polymarket directly or using unfiltered market dumps when you need category-scoped results.
Side effects
- Invalid or unknown tag ID returns empty results or an error
- Tag ID not found — use polymarket-tags endpoint first to discover valid IDs
- API returns stale data if Polymarket Gamma feed is delayed
- Payment failure (x402) if USDC balance is insufficient for the $0.05 call
- Malformed POST body or wrong bodyType causes 400-level error
