Output

Also includes a disclaimer note that probabilities are market-implied, not guaranteed predictions.

Technical details
Endpoint
POSThttps://api.vextorium.com/polymarket-mercados-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live, structured data from Polymarket prediction markets — including implied probabilities, volume rankings, and liquidity — for elections, sports, crypto, or macro events. Prefer this over scraping Polymarket directly or using generic search, as it returns structured probability data per outcome with sorting controls.
Side effects
- No markets found for the search query — returns empty markets array
- Invalid sort order value — request rejected or falls back to default
- Polymarket API unavailable upstream — returns error or empty result
- Limit parameter too high — may return fewer results than requested
