Getting Your API Key

Generate and manage your API keys through the Zerion API Dashboard. The dashboard lets you:

Create and manage API keys
Select and manage your plan, and view your usage limits
Create an organization and invite members

We offer two plans to help you begin:

Free Plan: No credit card required. Perfect for demos and initial testing.

Developer Plan – Requires a credit card, remains free to use, and provides higher usage limits for more extensive testing.

Choose the plan that fits your needs and start building right away.

Send your first authenticated request

Test Directly in the Docs

To try out endpoints directly from these docs, first generate an API key in the Zerion API Dashboard. Then paste it into the **Credentials **username field (no password needed) on the endpoint you want to test and click Try It!.

Making Requests Manually

Zerion API uses Basic Authentication.

To authenticate requests:

Take your API key.
Append a colon (:) to it.
Encode the result in Base64.

The dashboard’s code snippets automatically handle this transformation for you when you copy or run them.

You can find ready-to-use examples in the Get Started section of the dashboard.

Rate Limits

Rate limits depend on your plan. You can view and manage your plan in the Zerion API Dashboard.

If you exceed your rate limit, the Zerion API will return a 429 status code for every request beyond the limit until the rate limit window resets.

For any questions, contact us via the chat widget on this page or at api@zerion.io.
