Fetch is Linkup’s real-time page content extractor. Given a URL, the /fetch route returns a clean markdown rendering of the page, optimized for LLM consumption. Optional JavaScript rendering is available, along with optional raw HTML and extracted image URLs.

​
Parameters

ParameterDefaultDescription
url(required)The page to fetch. Must be a valid HTTP/HTTPS URL.
renderJsfalseRender the page’s JavaScript before extraction. Required for client-side-rendered pages (SPAs, dashboards, many modern marketing sites). See pricing for the rendered-call rate.
includeRawHtmlfalseReturn the original HTML alongside the markdown. Used for custom parsing or preservation of structures that markdown does not represent.
extractImagesfalseReturn a separate list of image URLs alongside the markdown.
In agentic pipelines, set renderJs to true by default. Many modern sites are client-side rendered; switch to false only after confirming the specific site renders server-side.
When and how to use renderJs, includeRawHtml, and extractImages is covered on the Fetch best practices page.

​
Constraints

Fetch is HTML only. Binary URLs (PDF, ZIP, image, video) return a 400 error.
Fetch does not authenticate. Pages behind a login wall return what an anonymous visitor would see.
Pages over 20 MB return a 400 error. See the rate-limits page for request-rate limits.

Example

Get your API key

Create a Linkup account for free to get your API key.
from linkup import LinkupClient

client = LinkupClient(api_key="<YOUR_LINKUP_API_KEY>")

response = client.fetch(
    url="https://docs.linkup.so",
    render_js=True,
)
print(response)
Successful response: 
{
  "markdown": "# Linkup docs\n\nGet started for free, no credit card required...",
  "rawHtml": "<!doctype html><html>...</html>",
  "images": [
    { "alt": "Linkup logo", "url": "https://docs.linkup.so/images/logo-light.svg" }
  ]
}
rawHtml is present only when includeRawHtml is true. images is present only when extractImages is true. markdown is always returned.
