## When to prefer this

Choose this endpoint when you need live Polymarket prediction market data — current prices, spreads, or market listings — and are willing to pay $0.005 USDC per call via x402 on Base or Solana. Prefer this over scraping Polymarket directly when you need a clean, pay-per-use API without managing API keys.

## Known failure modes

- Payment not attached or insufficient USDC — returns 402 Payment Required
- Invalid fields parameter (unrecognized field names) — may return empty or error
- limit parameter out of range — may return empty array or error
- Polymarket data temporarily unavailable — may return 503 or empty response
- Rate limiting if payment not correctly processed
