How this service works
Call when an agent needs summary text via summary from a public page or HTML (SSRF-safe). Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/css-summary first.
Output
Returns a summary text string distilled from the provided URL's fetched content or the supplied raw HTML. The summary captures the main points or readable body text of the page in condensed form.
Example use cases
Summarize news article before sharing
“Grab the main summary from this news article URL https://www.bbc.com/news/technology-67890123 so I can quickly decide if it's worth reading.”
Digest competitor landing page
“Summarize what this competitor's homepage is about: https://www.acmecorp.com — I want to understand their value proposition quickly.”
Extract readable text from HTML snippet
“I have some raw HTML from a scraped product page, can you extract and summarize the readable content from it so I know what the page is actually saying?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-summary?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick text summary of a public URL or raw HTML without standing up your own scraping or NLP infrastructure. It is SSRF-safe, making it suitable for agent pipelines that fetch user-supplied URLs. Prefer the free POST /v1/sandbox/css-summary endpoint first if available; fall back to this paid endpoint ($0.002 USDC) when the sandbox is unavailable or rate-limited.
Side effects
- URL is not publicly accessible or returns a non-200 status
- URL is flagged as SSRF risk (private IP range, localhost, etc.) and rejected
- HTML input exceeds 200,000 character limit
- URL string too short (under 8 characters) or too long (over 2048 characters)
- Page has no extractable text content (e.g. pure image or JavaScript-rendered SPA)
- Network timeout fetching the URL
