Every user within Pexi has an API-key that can be found in the Profile settings. In the profile settings you can also reset the API-key if needed. With the API you've got access to the same advertisers as within the interface. The API-key can be added to a request as a X-Authorization header.
--header 'X-Authorization: <some-api-key>'
Our Web Application Firewall automatically detects abuse of the API endpoint and resets your API-key. In addition, your IP can be blocked in case of abuse. Every user is responsible for the use and/or traffic from his API key.
