API Enterprise
The options flow of every US-listed underlying on one session, one row each: print counts by type, premium, the buyer, seller and sentiment shares of premium, and the ORTEX directional flow score.
Built for enterprise consumers: the response is uncharged (no credits), and every row carries the full instrument-identity block so it can be joined straight onto your own security master.

Region and date
Coverage is US-listed options only. Use region to select the universe (defaults to US; ALL or any region that includes the US also works; a region with no US listings returns 400 invalidRegion) and date to select the US/Eastern session (defaults to the latest session with prints). Only underlyings with at least one print in the session appear.
How the shares and the score are built
The buyer, seller, mid, bullish and bearish shares are taken over the premium of the prints that have the quote at execution, which is held from the 19 October 2026 session; earlier sessions report them as null. The ORTEX flow score signs every print by its payoff direction against the underlying: its break-even versus the underlying's last price in the 20 minutes before the print (the print's ortexBetDirection on the Options Flow endpoint). The bullish share of premium and the bullish share of prints are combined and re-centred on zero, then damped where the evidence is thin - few prints on either side, a small net bet or under $5M of premium - so +65 on 3,000 prints means more than +65 on 30. Prints whose underlying did not trade in that window are left out of the score; when none traded the score is null.
