How this service works
The rel="dns-prefetch" links of a page: every matching <link>/<a> with href, resolved to absolute URLs, with a count. Link-relationship discovery. $0.01 per page.
Output
A list of all <link rel='dns-prefetch'> and matching <a> elements found on the page, with each href resolved to an absolute URL, plus a total count of matching links.
Example use cases
Third-party dependency audit
“I want to know which external domains https://shopify.com is prefetching DNS for — can you pull all the dns-prefetch links from their homepage and list the resolved URLs?”
Competitor technology intelligence
“Can you check https://stripe.com and tell me every domain they're hinting at with dns-prefetch links? I'm trying to understand what third-party services they rely on.”
Site performance resource hint check
“Pull the dns-prefetch link tags from https://nytimes.com for me — I want to see how many there are and what URLs they resolve to.”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/link-rel/dns-prefetch?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically discover DNS prefetch resource hints declared in a page's HTML, for tasks like auditing third-party dependencies, understanding a site's performance optimization strategy, or building an inventory of external domains a site preloads. Prefer this over generic link extractors when your focus is strictly on the dns-prefetch relationship type.
Side effects
- Page URL not provided or malformed — request fails with input validation error
- Target page returns non-200 HTTP status — no links extracted
- Target page has no dns-prefetch link elements — returns empty list with count 0
- Target page blocks scraping via bot detection — may return empty or error
- Relative hrefs that cannot be resolved to absolute URLs may be skipped
