How this service works
Fetch the fully rendered HTML of any URL after JavaScript execution.
Output
Returns the fully rendered HTML string of the target URL as it appears after all JavaScript has been executed in a headless browser, reflecting the live DOM state including dynamically injected content.
Example use cases
Example prompt
“Can you fetch the fully rendered HTML from https://example.com/dashboard — I need the post-JavaScript version of the page, not just the raw static source.”
Technical details
Endpoint
POSThttps://stableflare.dev/api/browser/contentWhen to prefer
Choose this endpoint when you need the HTML of a page that relies on JavaScript to render its content — such as React, Vue, Angular, or other SPAs — where fetching raw HTML would return an empty shell. Prefer this over static HTTP fetches when the target page's content is dynamically injected at runtime.
Side effects
- URL is unreachable or returns HTTP error — fetch fails with error response
- Target page takes too long to render — timeout error
- JavaScript on page causes crash or infinite loop — render failure
- Invalid or malformed URL provided — validation error
- Page requires authentication to access — returns login page HTML instead of target content
- Payment not processed — 402 payment required error
