How this service works
Call when an agent needs web manifest hrefs via link[rel='manifest'] from a public page or HTML (SSRF-safe). Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/css-manifest first.
Output
Returns the href value(s) found in link[rel='manifest'] elements within the specified page or HTML content, indicating where the site's web app manifest is located.
Example use cases
Detect PWA manifest for a website
“I need to find the web app manifest URL for https://shop.mystore.com — can you check what the link[rel='manifest'] tag points to on that page?”
Parse manifest from raw HTML snippet
“I have this HTML chunk from a page I scraped — can you pull out the manifest href from any link[rel='manifest'] element in it?”
Audit site for manifest presence
“I'm auditing https://myblog.io to see if it's set up as a PWA — can you check if there's a web manifest linked in the page and tell me the href?”

Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-manifest?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover a website's PWA/web app manifest location from either a live URL or raw HTML. Prefer the unpaid POST /v1/sandbox/css-manifest endpoint if available for free usage. Choose this paid endpoint when the sandbox is unavailable or quota is exhausted and you need reliable SSRF-safe manifest extraction.
