Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/market-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market for macro, crypto, AI, or political events. It is especially useful when you want whale sentiment and orderbook pressure in addition to simple odds. Prefer it over general news or sentiment APIs when you need quantified market-implied probability rather than qualitative opinion.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Stale data if Polymarket API is temporarily unavailable or rate-limited
- Ambiguous topic query matching multiple markets — may return aggregated or first-match result
- Payment failure via x402 if USDC balance is insufficient — returns 402 status
- Very niche or newly created markets may have low liquidity resulting in unreliable implied probabilities
