Technical details
Endpoint
GEThttps://agentdiet.dev/v1/event-probabilities?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates from actual prediction market traders for macro, crypto, geopolitical, or AI events. It is superior to news sentiment or analyst forecasts when you want market-implied consensus with volume and whale activity signals. Prefer this over general web search when you specifically need quantified probability estimates backed by real money.
Side effects
- Topic query too vague or ambiguous — no matching Polymarket market found
- Polymarket API or data feed temporarily unavailable — stale or empty response
- Payment not processed (HTTP 402) — requires $0.01 USDC per call via x402
- Rate limiting or quota exceeded — throttled response
- Market exists but has low liquidity — probabilities may be unreliable
