Technical details
Endpoint
POSThttps://x402.agentutility.ai/polymarket-searchWhen to prefer
Use this endpoint when an AI agent needs to discover or search Polymarket prediction markets programmatically, especially when filtering by topic, category, tag, or liquidity without needing to place trades or access order books. Prefer over scraping Polymarket directly because it provides a structured, agent-friendly API with USDC micropayment settlement.
Side effects
- No markets found matching query — returns empty results
- Invalid or unsupported filter parameters — may return error or unfiltered results
- Polymarket data unavailability — upstream data fetch failure
- Payment failure via x402 protocol — call not executed
- Rate limiting or quota exceeded — request rejected
