Endpoint
GEThttps://prompt-guard.agentdiet.dev/v1/crypto-betting-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live, real-time implied probabilities and crowd wisdom from Polymarket's prediction market orderbooks for crypto, macro, political, or AI events. Prefer this over news sentiment or social media analysis when you want market-priced probability estimates backed by actual money. Best for quantitative agents that need a numeric probability estimate rather than qualitative sentiment.
Side effects
- No matching Polymarket market found for the given topic — returns empty or null result
- Topic string too vague to match a specific market — may return multiple or unrelated markets
- Market may be resolved/closed — data reflects final settlement rather than live odds
- Payment failure via x402 if USDC balance is insufficient — HTTP 402 returned
- Rate limiting or upstream Polymarket API downtime causing stale or missing data
