Technical details
Endpoint
POSThttps://x402broker.com/v1/polymarket-odds?utm_source=zero.xyzWhen to prefer
Choose 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 orderbook — particularly when whale sentiment and volume context are needed alongside raw odds. Prefer this over general web search when you want structured, numeric probability data rather than news articles or opinion pieces.
Side effects
- Topic keyword matches no active Polymarket markets — returns empty or low-confidence result
- Ambiguous topic resolves to multiple markets — may return the wrong market or a list requiring disambiguation
- Polymarket API or data feed unavailability causes timeout or stale data
- Payment failure via x402 protocol blocks request before execution
- Very niche or newly created markets may have thin orderbooks and unreliable implied probabilities
