Endpoint
GEThttps://defi-yield.agentdiet.dev/v1/polymarket-prediction-stream?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 on Polymarket. Prefer this over news sentiment or analyst forecasts when you want market-implied probabilities backed by real capital and want whale positioning context. Best when the question can be framed as a binary Yes/No outcome.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Polymarket API unavailable or rate-limited — upstream timeout or 5xx error
- Ambiguous topic keyword matching multiple markets — may return unintended market data
- Market has already resolved — data may reflect final outcome rather than live odds
- Payment not processed (x402) — endpoint returns 402 Payment Required before data is returned
