Authentication
How to authenticate with the Quartr API
How to generate an API key
Our API uses header-based authentication to ensure secure access. Each request to the API must include a key in the headers to verify your identity and permissions. You can create and manage your API keys through our portal.
Log In to the Portal
Access your account by logging into the Quartr Portal.
Navigate to API-keys
Once signed in, navigate to the API-keys section.
Generate a New API Key
Click the “Create New API Key” button, and set a desired validity period for the key. The new key should now appear in the list of API keys.
Use the API Key in Requests
Include this key in the request header using x-api-key as the header name.
Test the API Key
Try using your new API key by following one of our getting-started guides, or explore the API Reference for more details.
Dataset access
Your access to datasets is determined by your subscription plan. Each API key is associated with the permissions specific to your plan. Attempts to access datasets outside of your plan’s scope will result in a 403 Forbidden error.
Rate limit
There is no rate limiting for paying customers. However, demo accounts are subject to certain restrictions. These include a daily limit of 200 requests and a fixed pagination limit, preventing users from modifying the number of results per request. As a result, only ten results can be retrieved per request. However, cursors can still be used to iterate over results.
Important: Please note that starting December 1, 2025, all accounts will be subject to a rate limit of 50 requests per second. This change is being implemented to ensure fair access for all users and to maintain the performance of our API. We recommend that you optimize your API usage to stay within this limit.
