The real-time options flow API
Net call and put premium bars plus significant prints - sweeps, blocks and splits - delivered as compact JSON built for charts, bots and alerts.
Part of the Quant plan.

Follow the premium, not the noise
Flow that answers one question fast: is real money leaning into calls or puts, right now - and who just placed the big bet?
One array per session, trivially chartable
Aggressor-signed call and put premium bucketed per minute. Three numbers per bar - timestamp, net call premium, net put premium - small enough to poll from anything.
- [ts, call, put]positional arrays instead of verbose objects
- resolution=1mdown to the minute for scalps, coarser for swings
- day=YYYY-MM-DDreplay any past session, bar by bar

The trades that move positioning
Sweeps, blocks and splits above the noise floor - each with side, strike, expiration and premium, so your code can explain a move instead of just noticing it.

Premium drift for the trend, prints for the trigger. Both under the same key.
