Technical details
Endpoint
POSThttps://x402.valkyry.fr/metadata?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need lightweight, structured page metadata (title, description, language, OG image, reading time) from a publicly accessible URL without needing full page content or HTML. Ideal for link previews, content enrichment pipelines, or agent workflows that need to quickly characterize a web page before deciding how to process it further.
Side effects
- Private, loopback, or metadata IP addresses are rejected with an error
- Non-publicly-reachable URLs return an error
- Malformed or non-URI input returns a validation error
- Pages with no metadata return empty or null fields for missing properties
- Payment failure via x402 protocol returns a 402 response before content is served
