Technical details
Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/polymarket-prediction-stream?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs real-time crowd-sourced probability estimates for macro, crypto, political, or AI events sourced directly from Polymarket's live orderbooks. Prefer this over general news or sentiment APIs when you need quantified market-implied probabilities and large-trader (whale) positioning data rather than qualitative sentiment.
Side effects
- Topic keyword matches no active Polymarket markets — returns empty or null results
- Polymarket API or upstream data unavailable — timeout or 5xx error
- Ambiguous topic string matches multiple markets — may return aggregated or first-match data
- Payment not processed (HTTP 402) — request blocked without valid x402 payment header
