How this service works
The rel="modulepreload" 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> and <a> elements with rel='modulepreload' found on the page, each with its href resolved to an absolute URL, plus a total count of matching links.
Example use cases
Audit site module preloading strategy
“Check https://shop.acme.com and list all the JavaScript modules it preloads with rel=modulepreload, including the resolved absolute URLs and a total count.”
Competitor tech stack research
“I want to understand what ES modules rival.io preloads on their homepage — can you pull all their modulepreload link hints and show me the full list?”
Performance regression monitoring
“Scan https://myapp.io and tell me every rel=modulepreload link it has right now so I can compare against last week's list and spot any regressions.”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/link-rel/modulepreload?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically discover rel=modulepreload resource hints on a page, such as auditing JavaScript module preload strategies, reverse-engineering a site's module loading architecture, or monitoring changes to preload directives over time. Prefer this over generic link extractors when you care specifically about ES module preloading performance hints.
Side effects
- Page is unreachable or returns non-200 status — empty result or error response
- Page has no rel=modulepreload links — returns empty list with count 0
- Dynamic/SPA page where modulepreload links are injected client-side may not be captured if server-side HTML is fetched only
- Invalid or malformed URL input causes request failure
