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?

Premium drift

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

Significant prints

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.

How it works

Plugged into the tape in three steps

Get on Quant
The options flows API ships with the Quant plan, alongside the full API catalog.
Generate your key
Mint a key in Dashboard → API. Bearer or X-API-Key, your call.
Poll and plot
GET /v1/flows once a minute and you have a live premium drift chart. That's it.

Truly real-time

Bars update live intraday - the same feed that powers QuantWheel's flow dashboards and the TradingView overlay, not an end-of-day file.

Compact by design

Payloads stay small enough to poll every minute from bots, dashboards and serverless functions without blowing budgets.

Prefer prompts over polling?

Ask your AI what's sweeping right now

The same flow feed ships as MCP tools - connect QuantWheel to Claude or Cursor and ask about drift and prints in plain English.
