Quick Start Guide

What You'll Get

The FlashAlpha Lab API gives you programmatic access to real-time options exposure analytics:

• GEX — Gamma exposure by strike (dealer hedging pressure)
• DEX — Delta exposure (directional positioning)
• VEX — Vanna exposure (vol-sensitivity of dealer delta)
• CHEX — Charm exposure (time-decay of dealer delta)
• Stock & option quotes, key levels, AI narrative, and more

The free Starter plan includes 100 requests/day — enough to explore the full API. You can also use the interactive tools to visualize exposure data without writing code.

Step 1: Create Your Free Account

1. Go to flashalpha.com/pricing
2. Click Get Started Free under the Starter plan
3. Enter your email and choose a password
4. Check your inbox and click the confirmation link

Step 2: Copy Your API Key

1. Sign in to your FlashAlpha account
2. Your API key is displayed on the Profile page
3. Click the copy button next to your key

Your API key authenticates every request. Pass it in the X-Api-Key header.

Step 3: Make Your First Call

Let's fetch gamma exposure (GEX) for SPY:

curl -H "X-Api-Key: YOUR_API_KEY" \
  "https://lab.flashalpha.com/v1/exposure/gex/SPY"

import requests

resp = requests.get(
    "https://lab.flashalpha.com/v1/exposure/gex/SPY",
    headers={"X-Api-Key": "YOUR_API_KEY"}
)
data = resp.json()
print(f"Net GEX: ${data['net_gex']:,.0f}")
print(f"Flip: {data['gex_flip_point']}")

const resp = await fetch(
  "https://lab.flashalpha.com/v1/exposure/gex/SPY",
  { headers: { "X-Api-Key": "YOUR_API_KEY" } }
);
const data = await resp.json();
console.log(`Net GEX: $${data.net_gex.toLocaleString()}`);
console.log(`Flip: ${data.gex_flip_point}`);

You should get a JSON response like this:

{
  "symbol": "SPY",
  "underlying_price": 597.505,
  "as_of": "2026-03-06T16:30:45Z",
  "net_gex": -2500000000,
  "gex_flip_point": 590.0,
  "gex_interpretation": "Negative gamma — dealers amplify moves",
  "strikes": [
    { "strike": 590.0, "call_gex": 1200000, "put_gex": -3400000, "net_gex": -2200000 }
  ]
}

Step 4: Try the Interactive Tools

Don't want to write code yet? Use the interactive tools to visualize exposure data in your browser:

• Gamma Exposure (GEX) — dealer hedging pressure by strike
• Delta Exposure (DEX) — directional positioning
• Vanna Exposure (VEX) — vol-sensitivity flows
• Charm Exposure (CHEX) — time-decay flows
• Volatility Surface — 3D IV surface across strikes and expirations
