Endpoint
GEThttps://prompt-guard.agentdiet.dev/v1/macro-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market for macro, crypto, or AI events — especially when you want not just odds but also volume and whale sentiment to gauge conviction. Prefer this over generic news sentiment APIs when you want market-implied probabilities rather than qualitative sentiment, and over static data sources when you need live orderbook data.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Stale or delayed data if Polymarket API is temporarily unavailable
- Ambiguous topic keyword matching multiple unrelated markets — results may include irrelevant markets
- Payment failure via x402 resulting in 402 response before data is returned
- Rate limiting or timeout if the upstream Polymarket feed is under heavy load
