Frequently Asked Questions (FAQ)

How do I get an API key?

After choosing a plan, you will be directed to our management platform where you can sign up and immediately generate your unique API key from the dashboard.

What kind of data do I receive via the API?

Responses are in JSON format and include, depending on the plan, the page title, .onion URL, a text snippet, relevance score, and advanced metadata like indexing date and HTTP headers.

How is my usage tracked?

Our system tracks the number of requests made with your API key over a 30-day cycle. You can monitor your usage in real-time from your personal dashboard.

Can I change or cancel my plan?

Of course. You can upgrade, downgrade, or cancel your subscription at any time directly from the management platform, effective from the next billing cycle.
