How to Get a Nasdaq Data Link API Key
Nasdaq Data Link (formerly Quandl) gives every account a free API key that raises your rate limits and unlocks the full catalog of free datasets.
- Create a free account at https://data.nasdaq.com/sign-up.
- Open your Account Settings — your API key is displayed there.
- Append it to any request with the
api_keyquery parameter.
The base URL is https://data.nasdaq.com/api/v3. Many datasets (central-bank, government, and economic data) are free with a key; premium datasets require a separate subscription.
curl "https://data.nasdaq.com/api/v3/datasets/LBMA/GOLD/data.json?api_key=YOUR_API_KEY"
Without a key you're limited to a small number of anonymous calls per day; with the free key you get a much higher daily allowance. Keep the key server-side.
Note: this is different from the unofficial api.nasdaq.com/api/quote/... endpoint (used by nasdaq.com's website, which only needs a browser-like User-Agent). For the documented, supported API, use Nasdaq Data Link at data.nasdaq.com as shown above.
