Technical details
Endpoint
GEThttps://defi-yield.agentdiet.dev/v1/crypto-betting-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates and trader sentiment for macro, crypto, or AI events sourced specifically from Polymarket's orderbook data. Prefer this over general news or sentiment APIs when you want market-implied probabilities backed by real money, volume signals, and whale activity rather than social media sentiment or analyst forecasts.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Topic string too vague or ambiguous, returning unrelated markets
- Polymarket API or upstream data feed temporarily unavailable, causing stale or missing data
- Rate limiting or payment failure (x402) blocking the request
- Market may be resolved/closed, returning historical rather than live data
