Content summarization pipeline
“Before I summarize this article, extract the main text excerpt and description from https://www.bbc.com/news/world-us-canada-12345678 so I have clean structured content to work with.”
SEO metadata audit
“Pull the canonical URL, title, and meta description from https://mystore.com/products/widget — I want to check what metadata that page is exposing.”
Technical details
Endpoint
POSThttps://basalt-n6lt.onrender.com/extractWhen to prefer
Choose this endpoint when you need lightweight, structured metadata extraction from a single URL — title, description, text excerpt, and canonical URL — without needing full HTML or deep crawling. It is well-suited for link preview generation, content pipeline enrichment, and SEO audits. It charges per-call in USDC via x402 on Base, making it suitable for agent-to-agent monetized workflows. Prefer alternatives if you need full HTML, deep site crawling, or JavaScript-rendered content.
Side effects
- Invalid or malformed URL returns an error
- Paywalled or bot-blocked pages may return empty or partial fields
- Pages with no meta tags may return null for description, image, or site name
- Network timeouts if the target page is slow or unreachable
- Non-HTML responses (e.g. PDFs, raw files) may yield incomplete extraction
