Technical details
Endpoint
POSThttps://prediction.hergertsynthora.com/serviceWhen to prefer
Use this endpoint when you need real-money crowd-sourced probability estimates from Polymarket — the leading prediction market — rather than model-generated forecasts or news sentiment. Ideal when the user wants quantified odds, market volume, or directional signals on a specific upcoming event, political outcome, crypto price question, or any other binary prediction market topic.
Side effects
- No matching Polymarket question found for the input query — result may be empty or null
- Ambiguous keyword matches multiple markets — result may reflect the wrong question
- Stale data if Polymarket API is lagging — volume and prices may be delayed
- Payment failure (x402) if USDC balance insufficient — request not processed
- Malformed input string causes lookup failure — ok returns false
