How this service works
Call when an agent needs link rel=manifest hrefs extracted from a public page or HTML (SSRF-safe). Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/profile-rel-manifest first.
Output
A list of href values found in link[rel=manifest] elements on the given page or HTML, returned in a structured response. If no manifest links are present, an empty list is returned.
Example use cases
PWA manifest discovery for audit
“I'm auditing a list of websites for Progressive Web App support — can you pull out any link rel=manifest hrefs from https://app.example.com so I can check if they have a manifest declared?”
Extract manifest from raw HTML snippet
“I have this raw HTML from a crawl and I need you to find all the link rel=manifest href values in it — can you parse it out for me?”
Verify manifest URL before deployment
“Before we go live, can you check https://staging.myapp.io and extract the manifest href so I can confirm the correct manifest file is being referenced?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-rel-manifest?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to reliably discover web app manifest URLs (PWA manifests) from a public URL or raw HTML in an SSRF-safe environment. Prefer this over general-purpose HTML parsers when you specifically need link[rel=manifest] hrefs without setting up your own scraping infrastructure. If a free sandbox version (POST /v1/sandbox/profile-rel-manifest) is available, try that first to avoid the $0.009 USDC cost.
Side effects
- URL is unreachable or returns a non-200 status — endpoint may return an error or empty result
- SSRF-blocked URL (private IP range or localhost) — request is rejected for security reasons
- HTML input exceeds 200,000 character limit — request is rejected
- URL string shorter than 8 characters or longer than 2048 characters — validation error
- Page has no link[rel=manifest] elements — returns an empty list
- Malformed HTML that cannot be parsed — may return empty result or parsing error
