How this service works
Call when an agent needs paragraph text via p from a public page or HTML (SSRF-safe). Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/css-p first.
Output
Returns the text content extracted from all <p> elements found in the provided URL or HTML, giving the agent the human-readable paragraph text from the page stripped of markup.
Example use cases
Article body text extraction
“Grab all the paragraph text from https://techcrunch.com/2024/01/15/some-article — I want the main readable content, not the navigation or headers.”
Raw HTML paragraph parsing
“I have some raw HTML from a page I scraped — can you pull out all the paragraph text from it? Here's the HTML: <html><body><p>First paragraph.</p><p>Second paragraph.</p></body></html>”
Research page content retrieval
“Extract the readable paragraph content from https://en.wikipedia.org/wiki/Artificial_intelligence so I can summarize what it says.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-p?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract paragraph text from a public webpage or raw HTML and want an SSRF-safe, hosted extraction service rather than running your own scraper. Prefer this over generic scraping tools when you specifically need p-tag text content and are working in an agent context that supports x402 micropayments. Try the free sandbox endpoint POST /v1/sandbox/css-p first before paying.
Side effects
- URL is blocked or returns non-200 status — extraction fails with an error
- SSRF protection blocks private/internal IP ranges — returns an error for restricted URLs
- HTML contains no <p> elements — returns empty or minimal result
- URL content is JavaScript-rendered (SPA) and server-side HTML has no paragraph text — returns empty result
- HTML input exceeds 200,000 character limit — request rejected
- URL string shorter than 8 characters or longer than 2048 — validation error
- Payment of $0.005 USDC not provided — 402 Payment Required response
