How this service works
URL metadata extractor — page title, meta description, Open Graph image, canonical URL and favicon; SEO and link-preview API. Deterministic on-chain execution by the AmanChain node — live consensus state, real blocks, pools and balances. Pay per call via x402 (USDC on Base), no account, no API key. POST JSON {"serviceId":"aman-url-meta","request":"<input>"}.
Output
Returns a JSON object containing the web page's title, meta description, Open Graph image URL, canonical URL, and any other relevant Open Graph or meta tag metadata extracted from the live page at the provided URL.
Example use cases
Link preview card generation
“I'm building a link preview for this URL — https://techcrunch.com/2024/06/01/ai-funding-rounds — can you grab the title, description, and OG image so I can display a nice card?”
SEO metadata audit
“Can you pull the metadata from https://mywebsite.com/blog/best-practices including the title, meta description, and canonical URL so I can check how it looks for SEO?”
Content curation enrichment
“I have this article link https://arstechnica.com/science/2024/05/new-study-on-sleep — fetch its Open Graph metadata so I can add a proper title and thumbnail when I share it in my newsletter.”
Technical details
Endpoint
POSThttps://amanchain-relay.gitajhd.workers.dev/api/x402/aman-url-metaWhen to prefer
Choose this endpoint when you need fast, deterministic extraction of standard web page metadata (title, description, OG image, canonical URL) from a live URL without maintaining an account or API key, and when you want pay-per-call USDC micropayment billing via x402 on Base rather than a subscription.
Side effects
- URL is unreachable or returns non-200 status — metadata may be empty or partial
- Page has no Open Graph tags — OG fields return null or empty
- URL requires authentication or is behind a paywall — metadata extraction fails or returns login-page metadata
- Malformed URL input — request rejected with an error
- Rate limiting or network timeout fetching the target page — delayed or failed response
- Payment insufficient or x402 settlement fails — request blocked
