FAQPage Schema

How do I fetch JavaScript-rendered web content from a URL?▼

To fetch JavaScript-rendered web content, you can post target URLs to the Fetch API and extract the text directly from the 'results[].content' field. This approach reliably captures dynamically loaded page elements.

Do I need an API key to scrape rendered web pages?▼

Yes, you need a valid TINYFISH_API_KEY. The tool verifies the presence of this API key before routing your URL fetching requests through its rendering service.

Can I capture screenshots of web pages during content extraction?▼

Yes, you can capture web page screenshots as base64 PNG images alongside standard content extraction. This allows you to retrieve visual snapshots of fully rendered URLs for processing.

How do I access country-specific web content during URL fetching?▼

You can access country-specific web content by routing your URL fetching requests through a geo-targeted proxy. This proxy support ensures accurate rendering of region-restricted pages.

What format is extracted when scraping JS rendered pages?▼

The content extraction process returns fetched web page data as markdown. This converts the rendered HTML output into structured markdown text for easy downstream processing.

Why does my web scraping tool miss dynamically loaded elements?▼

Standard scraping tools miss dynamic elements because they do not execute JavaScript rendering. You need a fetching service that fully renders the page before extracting the generated content.
