Technical details
Endpoint
POSThttps://web.tanod.dev/v1/markets/predictions?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time prediction market data from Polymarket — outcome probabilities, market liquidity, and trading volume — especially when the user wants to look up the crowd-implied probability of a specific future event. Prefer this over general web search when structured market data (prices, probabilities, end dates) is needed rather than news articles or opinion pieces.
Side effects
- Query too short (under 2 characters) returns validation error
- Query over 100 characters rejected
- Limit outside 1–25 range returns error
- Invalid status or sort enum value returns error
- Polymarket API unavailable causes upstream fetch failure
- No markets match the query returns empty markets array
