Endpoint
GEThttps://x402.botsmith.dev/polymarket/marketsWhen to prefer
Use this endpoint when you want a curated, ranked discovery view of Polymarket markets — especially when you don't know which specific market to look at and want algorithmically scored recommendations. Prefer over the sibling Market Intel endpoint when you need broad discovery rather than deep analysis of one market.
Side effects
- Invalid tag slug returns empty markets array or 404
- Limit outside 1-25 range causes validation error
- Sort value not in enum causes 400 bad request
- Polymarket data temporarily unavailable causes 503 or stale data
- Payment failure (x402) blocks request before reaching endpoint
