Does it execute JavaScript?

No. The extractor performs a standard HTTP GET request and parses the static HTML. Pages that render meta tags exclusively via JavaScript may return empty fields.

What is the timeout for fetching the URL?

The request times out after 10 seconds. If the target server is slow or unreachable, the API returns a partial result with the error field populated.

Can I use it to audit my own site?

Yes. Pass your page URL and the API returns all SEO meta tags in a structured JSON, ready to integrate into your own audit dashboard or CI pipeline.

Do I need a credit card to get started?

No. When you sign up you receive 1,000 free tokens to try any module. You only need to pay when you want more tokens.

How many tokens does each call consume?

It depends on the module. Simple validators (email, phone, IP) consume 1 token. More complex modules (URL checker, event planner, LLM modules) consume 2–5 tokens.
