API reference

Getting started

API access is available for Chrome-Stats Premium subscribers. If you have not already done so, please sign up to our Premium plan to unlock API access, download raw data, run advanced search queries, track unlimited extensions, access longer stats trends, and more!
Once you are a premium subscriber, you will need to create an API key in the Chrome-Stats API key console. The API key will allow us to identify your request, grant you access to premium resources, bypass our web application firewall, etc. When using an API, be sure to include your API key in the request header x-api-key: <your-api-key>. Do NOT share your API keys with other users.
If your API key is ever leaked publicly, you can go to Chrome-Stats API key console to delete it and create a new API key.

Each domain will give you the details for the extension in the corresponding platform. Using the extension ID on the wrong platform will yield a 404 Not Found error response.

Rate Limits and Quota

We recommend you keep your usage under the following limit:
Requests / min
Requests / day
When we start enforcing the limit, you will get a 429 status response if you have used past the limit.
Currently we do not enforce any rate limits or quota on our API. However, we reserve the rights to start enforcing them to prevent abusive use. If your usage of our API is expected to be above the limits, please contact us at [email protected].
