Quickstart

Get an API key and make your first request in two minutes.

1. Get an API key

Create a key from Dashboard → API & MCP (accept the API terms first). Keys are prefixed qw_live_ and require an active Quant subscription - the Quant plan is the only plan with API access.

The key is shown once at creation. Store it in a secrets manager - regenerating replaces it, so old copies stop working.

2. Make your first request

Pull the live gamma exposure profile and key levels for SPY.

curl -H "Authorization: Bearer qw_live_YOUR_KEY" \
  "https://quantwheel.com/api/v1/gex?symbol=SPY"

3. Read the response

200 OK

}

A negative totalGEX (gammaZone negative) means dealers amplify moves; gammaInflection marks the spot level where that regime flips. That single response already powers a regime dashboard.
