How this service works
Pay-per-call data tools for developers and AI agents: company registers, documents, tenders, rates and on-chain facts as MCP tools, x402 endpoints and Apify Actors.
Output
A JSON object containing a results array where each entry includes the final URL, HTTP status, page title, H1, meta description, Open Graph object, Twitter card object, favicon URL, canonical URL, language, hreflang tags, detected feeds, JSON-LD types, content type, theme color, robots meta, redirect flag, and generator. Also includes aggregate counts of succeeded, failed, and billableResults, plus a fetchedAt timestamp.
Example use cases
Link preview card generation
“I need to generate a link preview for https://openai.com/blog/chatgpt — can you grab the title, description, Open Graph image, and favicon so I can render a card?”
Batch SEO metadata audit
“Pull the metadata for these five pages for me: https://example.com, https://example.com/about, https://example.com/pricing, https://example.com/blog, https://example.com/contact — I want the title, canonical URL, meta description, and language for each.”
Feed discovery for content aggregator
“Can you check https://www.theverge.com/ and tell me what RSS or Atom feeds it exposes, plus the page language and any hreflang tags?”
Technical details
Endpoint
GEThttps://api.ambolt.dev/v1/url-metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured web page metadata (title, description, OG tags, feeds, canonical URLs, language) from one or many URLs without running a full headless browser. It is especially useful for link preview generation, SEO audits, feed discovery, and enriching URLs with display metadata. Prefer it over generic scraping tools when you only need head/meta content rather than full page HTML or rendered DOM.
Side effects
- URL is not publicly accessible or returns non-200 status — that URL appears in failed count with ok:false
- URL points to a non-HTML resource (PDF, image, etc.) — content type is reported but metadata fields may be empty
- Malformed or invalid URL in input — request may be rejected with a validation error
- Target page blocks crawlers via robots.txt or firewall — may return failed with no metadata
- Rate limit or payment failure — request rejected with 402 or 429 error
- Up to 20 URLs per call; exceeding maxItems causes schema validation failure
