Endpoint
GEThttps://x402broker.com/v1/polymarket-live-odds-feed?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live, real-money crowd-sourced probability estimates for macro, crypto, or AI events — particularly when you want orderbook depth, trading volume, and large-trader (whale) sentiment rather than just a headline price. Prefer it over news APIs or sentiment scrapers when you want market-implied probabilities rather than qualitative opinion.
Side effects
- No matching Polymarket market found for the given topic — returns empty or null result
- Polymarket API unavailable or rate-limited — upstream error propagated
- Ambiguous topic keyword matching multiple markets — may return the most liquid or first match
- Stale data if Polymarket orderbook has low liquidity or inactive market
- Payment not processed (x402) — endpoint returns 402 before data is delivered
