How this service works
The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.
Output
Returns structured metadata extracted from the target URL including page title, meta description, Open Graph properties (og:title, og:description, og:image, og:url), canonical URL, author, and any other meta tags present in the HTML head. Each response also includes a cryptographic audit record with chain hashing for provenance verification.
Example use cases
Link preview card generation
“Pull the metadata from https://www.bbc.com/news/technology-67890123 so I can build a preview card — I need the title, description, and OG image URL.”
SEO meta tag audit
“Extract all the meta tags from https://example.com/landing-page so I can check whether the title and description are properly set for SEO.”
Article enrichment for content pipeline
“I have this article URL https://medium.com/@author/my-article-abc123 — can you fetch its metadata so I can pull the author, publish date, and summary to store alongside it?”
Technical details
Endpoint
GEThttps://api.strale.io/x402/v2/meta-extractWhen to prefer
Choose this endpoint when you need structured, auditable metadata extraction from a URL with cryptographic provenance tracking. Ideal for compliance-sensitive pipelines, content enrichment workflows, or link preview generation where you need a verifiable record of what was returned. The built-in audit chain distinguishes it from generic scraping services.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with an error
- Target page has no meta tags — returns empty or minimal metadata fields
- URL is behind a login wall or bot protection — content cannot be fetched
- Malformed or invalid URL input — request rejected with validation error
- Target page returns very large HTML — may time out or return partial data
