How Ahrefs API usage is calculated
All requests and endpoints consume API units. The cost depends on the number of rows in the response and the fields requested. The minimum cost for any request is 50 units.
Some API endpoints are free (cost 0 API units), and will be noted accordingly in the documentation:

Frequently Asked Questions
Can I still use API v2 directly or through Integrations?
API v2 has been fully deprecated and can no longer be used, either directly or through Integrations. The new Integrations system is built entirely on API v3. More details can be found here.
I'm building an application and would like to integrate the Ahrefs API. Do I have to purchase the Ahrefs API?
