Side effects
- Topic keyword too vague — no matching Polymarket market found, returns empty or error response
- Polymarket API unavailable or rate-limited — upstream data fetch fails
- Topic string too short or malformed — validation error
- Market exists but has very low liquidity — probabilities may be unreliable or missing
- Payment not processed (HTTP 402) — call blocked if x402 payment not included
