Supported Markets
Understand the assets, timeframes, data schemas, and availability policies available through the PolyTest API.
Assets & timeframes
6 assetsPolyTest tracks prediction markets per asset on Polymarket. Each asset supports a subset of market timeframes (duration from open to resolution). Snapshots are captured at 8× per second on all timeframes. Use coin and market_type to filter in the API.

How Markets Work
Each market represents a binary prediction: will the price of a given cryptocurrency go Up or Down within the market's timeframe?
Market Lifecycle
- 1Market opens —
start_timeis set, trading begins - 2Snapshots are captured 8×/sec — probability prices update in real-time
- 3Market resolves —
winneris set to "Up" or "Down" - 4Data is archived — snapshots remain queryable via API
Probability Prices
price_up and price_down represent market-implied probabilities from 0.00 to 1.00.
A price_up = 0.65 means the market assigns a 65% probability that the asset price will be higher at resolution time.
These prices are derived from the Polymarket orderbook and update with each snapshot.
