How this service works
Call when an agent needs application/rss+xml alternate hrefs extracted from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/profile-rss first.
Output
A list of URLs found in the page's or HTML's <link rel='alternate' type='application/rss+xml'> tags, representing the RSS feeds advertised by the page. Returns the href values of all matching alternate link elements.
Example use cases
Blog RSS feed auto-discovery
“I want to follow TechCrunch in my RSS reader — can you extract all the RSS feed URLs from https://techcrunch.com so I know which ones to subscribe to?”
Podcast feed link harvesting
“Given this HTML snippet from a podcast hosting page, can you pull out all the application/rss+xml alternate href links so I can add them to my aggregator?”
News site syndication audit
“Check https://www.bbc.com/news and tell me every RSS feed URL advertised in the page's head — I need to know all the feeds they expose.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-rss?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover RSS feed URLs from a public webpage or raw HTML, particularly when SSRF safety is required. Prefer the free sandbox POST /v1/sandbox/profile-rss first; use this paid endpoint when sandbox access is unavailable or rate-limited. Choose this over a general web scraper when you specifically need RSS alternate link discovery without broader extraction overhead.
Side effects
- URL is private/internal (SSRF blocked) — request rejected
- URL is unreachable or returns non-200 status
- HTML contains no application/rss+xml alternate links — empty result returned
- HTML input exceeds 200,000 character limit
- URL exceeds 2,048 character limit
- Malformed HTML prevents parsing — partial or empty results
- Payment of $0.003 USDC not provided — 402 response
