Fast Markets
List fast-resolving markets, optionally filtered by asset and time window.
Parameters:
- asset: Crypto ticker to filter by (BTC, ETH, SOL, XRP, DOGE, ...).
Maps to a title search — e.g. asset=BTC searches for "Bitcoin".
- window: Duration bucket (5m, 15m, 1h, 4h, daily). Matches Polymarket's
standard crypto speed-trading tiers.
- venue: Filter by venue ('polymarket', 'kalshi', 'sim').
- limit: Max markets to return (default 50).
- sort: 'volume' to sort by 24h volume, 'resolves_at' for pure chronological.
- market_status: 'live' (in settlement window now) or 'upcoming' (not yet in
settlement window). Omit for all. Note: this filters by the strict
`is_live_now` semantic below — for "currently tradable on Polymarket"
use `is_orderbook_open` instead.
Field semantics (frequently confused):
- `is_orderbook_open` (bool): the market is accepting orders on Polymarket
right now. True for every market in this response — the `status='active'`
filter implies it. Equivalent to Gamma's `active && !closed`.
- `is_live_now` (bool): the market is inside its final settlement window —
the last `<window>` minutes before `resolves_at`. For a fast-5m market,
true only in the 5 minutes before resolution. This is stricter than
Gamma's "active" flag. Use this if you only want to act on markets in
their immediate price-discovery window. If you want all tradable markets,
use `is_orderbook_open` (or just consume the full list).
Equivalent to GET /api/sdk/markets?tags=fast[,fast-<window>]&q=<asset_name>
