Smart Money Flows
Ranks markets by absolute net S/A/B-grade whale flow over a requested timeframe. Use this discovery endpoint to answer where smart money is flowing before drilling into a specific market with /api/v1/market//intel. Pagination is anchored by an opaque cursor carrying the first page as_of timestamp so new whale trades do not reorder page 2.

}Rank markets by where graded traders are putting money. This is the “where is smart money flowing right now?” feed. It aggregates whale flow from S, A, and B grade traders. It ranks markets by absolute net flow over your chosen window.
Use it for discovery, before you know a
Cursor-paginated. The cursor is anchored to the first page’s
condition_id. Once you have a market, follow up with Get Market Intel for the single-market breakdown.
Common filters:
timeframe=24h— lookback window (1h,4h,24h, or7d).min_grade=B— minimum trader grade in the flow. The defaultBmeans S, A, and B graded traders only.platform=polymarketorplatform=kalshi.direction=YESordirection=NO— restrict to one side of the flow.category=crypto— case-insensitive exact match against the provider-backed market category.

API key authentication. Send your key in the Authorization header as Bearer oxi_sk_live_.... Live keys require an active Pro subscription and return live data.
Headers
Conditional GET validator from a previous ETag. Matching values return 304 Not Modified with an empty body.
Query Parameters
Lookback window for grade-filtered whale flow aggregation.
Available options:
1h, 4h, 24h, 7d Page size.
Required range:
1 <= x <= 100Opaque cursor from previous response's next_cursor. Encodes the first-page as_of timestamp plus the last row's absolute net flow and condition_id.
Filter by market category (case-insensitive). A canonical bucket name (e.g. Basketball) matches every provider member that folds into it (NBA, WNBA, NCAAB); a raw provider value also resolves to its bucket.
Filter by source platform. all is a request-side no-op.
Available options:
polymarket, kalshi, all Minimum latest trader grade included in the flow. Default B means S/A/B only; unranked traders are excluded.
Available options:
S, A, B, C, D, F Optional post-aggregate flow direction filter.
Available options:
YES, NO Was this page helpful?
