Technical details
Endpoint
GEThttps://prompt-guard.agentdiet.dev/v1/market-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events as reflected by actual money at stake on Polymarket. Prefer this over news sentiment or analyst forecasts when you want market-implied probabilities backed by financial incentives. Best for agents that need live prediction market odds without direct Polymarket API integration.
Side effects
- No matching Polymarket market found for the given topic — returns empty or null results
- Ambiguous topic keyword matches multiple markets — may return the wrong market or require refinement
- Stale or delayed data if Polymarket API or orderbook feed is temporarily unavailable
- Payment failure via x402 micropayment protocol preventing the call from completing
- Rate limiting if the endpoint is queried too frequently
