How this service works
Pay-per-call utilities for autonomous agents, paid with x402 (USDC on Base; no account, no API key).
Output
A JSON object containing: og (Open Graph key-value pairs), twitter (Twitter Card key-value pairs), title, description, url, canonical, lang, siteName, image, favicon, feeds (array of feed URLs), jsonLd (array of JSON-LD objects), and jsonLdTypes (array of detected schema types).
Example use cases
Social preview before posting
“Before I share this article link on social media, can you tell me what the og:title, og:image, and og:description are for https://techcrunch.com/2024/01/15/some-article/ so I know how it'll preview?”
RSS feed discovery for a blog
“Check https://martinfowler.com and tell me if there are any RSS or Atom feeds linked on the page, and what the site's canonical URL and language are.”
JSON-LD schema audit
“Fetch the metadata for https://schema.org/Product and tell me what JSON-LD types are present on the page and what the page's description and title say.”
Technical details
Endpoint
POSThttps://newbotlabor--254ecdfcc2de11f19b541607ee4eb77e.web.val.run/api/web/meta?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to quickly extract structured web metadata (OG, Twitter Card, JSON-LD, feeds, favicon) from a URL or raw HTML without setting up an account or API key. Ideal for agent preflight checks before sharing links, embedding content, or crawling pages. Prefer this over full scraping endpoints when you only need metadata signals, not body content. The pay-per-call x402 model (0.002 USDC) makes it cost-effective for sporadic or high-volume use without subscription overhead.
Side effects
- URL is unreachable or returns a non-200 status — metadata may be incomplete or empty
- HTML payload exceeds 3 MB limit — request rejected
- Page blocks bots or requires JavaScript rendering — og/meta tags may not be present
- Malformed HTML causes incomplete parsing — some fields may be null
- Payment fails or USDC balance insufficient — x402 payment required before response is returned
