How this service works
Call when an agent needs text of //summary via //summary from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/xpath-summary first.
Output
Returns the extracted text summary derived from the page's main content via XPath processing. The response contains clean, readable text stripped of HTML markup, suitable for downstream processing or display.
Example use cases
Extract article body from news URL
“Grab the main text content from this news article at https://techcrunch.com/2024/01/15/new-ai-startup-raises-funding and give me a clean summary.”
Summarize pasted HTML content
“I have this raw HTML from a product page — can you extract the main readable text summary from it so I can see what it says without all the tags?”
Research assistant web content fetch
“Pull the summary text from https://en.wikipedia.org/wiki/Large_language_model so I can see what the page says about LLMs.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-summary?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract the main readable text from a public web page given either a URL or raw HTML, and you need SSRF protection. Prefer the free sandbox endpoint (/v1/sandbox/xpath-summary) for development or cost-sensitive workflows; use this paid endpoint when the sandbox is unavailable or rate-limited. Choose this over general LLM-based summarization when you want deterministic XPath-based extraction rather than generative paraphrasing.
Side effects
- URL is not publicly accessible or returns a non-200 status
- SSRF protection blocks access to private/internal IP ranges or localhost
- HTML input exceeds 200,000 character limit
- URL exceeds 2048 character limit
- Page has no extractable XPath-compatible text content
- Network timeout reaching the target URL
- Malformed or invalid HTML that cannot be parsed
