How this service works
Call when an agent needs meta description content via meta[name='description'] from a public page or HTML (SSRF-safe). Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/css-meta-description first.
Output
Returns the text content of the meta[name='description'] tag found in the page or HTML — typically a short sentence or paragraph summarizing the page, as used for SEO and link previews. Returns empty or null if no such tag exists.
Example use cases
SEO audit of competitor pages
“Pull the meta description from https://www.competitor.com so I can compare it against our own page description for SEO analysis.”
Content enrichment pipeline
“I have a list of article URLs — start with https://blog.example.com/post-1 and extract the meta description so I can add it to our content database.”
Scrape description from raw HTML
“Here's a chunk of HTML I already downloaded — can you extract the meta description tag content from it without making any additional network requests?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-meta-description?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need the meta description tag content (meta[name='description']) from a public webpage or raw HTML, and don't want to parse HTML yourself. It is SSRF-safe, making it suitable for agent pipelines that process user-supplied URLs. Prefer the free sandbox POST /v1/sandbox/css-meta-description first to avoid the $0.005 USDC cost. Use it over general-purpose scraping tools when you only need this specific metadata field.
Side effects
- URL is unreachable or returns non-200 HTTP status — fetch fails
- URL points to a non-HTML resource (PDF, image) — no meta tag found
- Page blocks crawlers (robots.txt or JavaScript rendering required) — empty result
- HTML input exceeds 200,000 character limit — request rejected
- meta[name='description'] tag absent from the page — returns null/empty
- SSRF-blocked private/internal IP ranges — request rejected for safety
