ISO-8601 instant to answer as of, e.g. 2026-08-20T14:30:00Z. Omit for the current value. Resolves to the nearest chain snapshot AT OR BEFORE the requested time (never after, which would be look-ahead bias); the snapshot actually used and the lag are reported in meta.extra.as_of. Under positioning=flow the dealer flow map is rebuilt from the tape as it stood at that instant, so a given timestamp always returns the same numbers. Bounded by your plan's history window.

Comma-separated venue filter, e.g. deribit,bybit. Restricts the response to those venues' contribution, recomputed from the per-venue breakdown - it is a re-aggregation, not a post-hoc scaling. Unknown names are ignored; an all-invalid filter returns every venue rather than nothing. Venues: deribit, bybit, okx, binance, derive, thalex, delta_india, delta. A venue with no contracts on the surface contributes zero - use GET /v2/status to tell that apart from a venue that is switched off.
