Getting your API key
Twelve Data issues a personal API key with every account, including the free Basic plan. The key inherits the API credit limits and plan-gated features of your Twelve Data plan.
Sign in to Twelve Data
Sign in to your Twelve Data account.
- In the left sidebar, click API keys.
- If you don’t have an account yet, create one on the Twelve Data registration page. No payment details are needed for the Basic plan.

Find your secret key
In the API keys table, find the Secret key row. Its Token value is hidden by default.
- Click Reveal to show the token.

Copy the API key
Click the copy button next to the revealed token to copy your API key.
- Paste it into the API Key field in StackOne Hub.
- Click Hide key when you’re done so the token is no longer shown on screen.
- Keep this key private. Anyone who has it can spend your plan’s API credits.
