## When to prefer this

Choose this endpoint when you need AI-synthesized intelligence specifically about Polymarket prediction markets without managing API keys — ideal for agents that can handle x402 micropayments in USDC on Base. Prefer this over raw Polymarket APIs when you want pre-analyzed, AI-curated insights rather than raw market data.

- Invalid or missing query parameters — returns 400 Bad Request
- Polymarket data unavailable or API downtime — returns 503 or error payload
- Insufficient wallet balance to complete x402 micropayment
- Rate limiting or abuse detection on the SperaxOS backend
