What is GEX?
Flow vs std
Authorizations
Your BackQuant API key (same key as v1)
Headers
Query Parameters
Comma-separated symbols, e.g. BTCUSDT,ETHUSDT,SOLUSDT,HYPEUSDT.
{
"all-four": {
"value": "BTCUSDT,ETHUSDT,SOLUSDT,HYPEUSDT"
}
}
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, bullish, paradex. 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.
Optional sections: expected_move,max_pain,ranked,zones
Dealer positioning model. flow (default) is BackQuant's measured dealer model, available for BTC/ETH; it falls back to std when it cannot be produced for a symbol. std is the textbook convention (call:+OI / put:-OI). The response reports which model actually ran in meta.extra.positioning.

The meta block returned alongside every v2 response.
Every field after version/timestamp is optional because endpoints
attach different combinations - e.g. /v2/status skips symbol, the
chain endpoint sets extra.filter_hash, etc. Listing them here means
SDKs get a typed accessor for each instead of a generic meta: dict.
