Quickstart

Go to gexboard.com/account and find the API Access card. Click Add API Access. After Stripe confirms your payment, your key is shown once — copy it immediately to a password manager or .env file.

Your key looks like this:

Treat it like a password. Anyone with this key can read your GEXBoard data — and consume your rate limit.

Every request needs an Authorization: Bearer <your-key> header. No query string auth, no other transport. Use HTTPS only — http:// is not supported.

Don't hardcode the key in source. Read from environment variable, secrets manager, or .env:

# .env file (gitignored)
GEXBOARD_API_KEY=gxb_live_AbCdEfGh1JKLmnopQRSTuvwxYZ012345_aBcD

export GEXBOARD_API_KEY="gxb_live_…"
curl "https://gexboard.com/api/v1/radar?ticker=SPY" \
  -H "Authorization: Bearer $GEXBOARD_API_KEY"

import os
from dotenv import load_dotenv

load_dotenv()
KEY = os.environ["GEXBOARD_API_KEY"]

Pull the live GEX snapshot for SPY. This is the same payload your dashboard sees — Net GEX, Call Wall, Put Wall, Gamma Flip, dealer regime, and per-strike contributions.

curl "https://gexboard.com/api/v1/radar?ticker=SPY&dte=0" \
  -H "Authorization: Bearer $GEXBOARD_API_KEY" \
  -H "Accept: application/json"

import os
import requests

KEY = os.environ["GEXBOARD_API_KEY"]
r = requests.get(
    "https://gexboard.com/api/v1/radar",
    params={"ticker": "SPY", "dte": 0},
    headers={"Authorization": f"Bearer {KEY}"},
    timeout=10,
)
r.raise_for_status()
data = r.json()
print("Net GEX:    ", data["net_gex"])
print("Call Wall:  ", data["call_wall"])
print("Put Wall:   ", data["put_wall"])
print("Gamma Flip: ", data["gamma_flip"])
print("Regime:     ", data["dealer_mode"])

Expected response (truncated):

{
  "ticker":       "SPY",
  "spot":         737.62,
  "net_gex":      2.4e9,
  "call_wall":    745,
  "put_wall":     730,
  "gamma_flip":   735.5,
  "dealer_mode":  "positive_gamma",
  "strikes": [...],
  "updated_at":   "2026-05-08T22:55:30Z"
}

That's it. You're calling the same engine your dashboard uses, with the same per-second freshness during 0DTE sessions.
