Technical details
Endpoint
POSThttps://wafermap.xyz/v1/prediction-markets?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates on future events — elections, Fed decisions, crypto prices, sports outcomes — pulled directly from Polymarket's live order book. Prefer this over general news APIs when you want quantified market-implied probabilities rather than qualitative reporting, and over raw blockchain queries when you want pre-aggregated odds, volume, and liquidity in a single call.
Side effects
- No markets found for a very niche or misspelled query topic
- Limit exceeds maximum of 20 — request rejected
- Empty query with no sort specified may return default results
- Polymarket data may be slightly delayed or stale during outages
- Network or payment authentication failure returns no data
