How this service works
Screenshot any URL. Extract structured data. Monitor for changes. Developer API with pay-per-call pricing — no API keys, no accounts.
Output
Returns a JSON object with an audit section containing: SEO title analysis (presence, length, validity), Open Graph tag presence (e.g. og:title), total link count on the page, and the audited URL. Also includes payment metadata (payer address and price in USDC units).
Example use cases
Landing page SEO health check
“Audit https://mystore.com/product/running-shoes and tell me whether it has a proper title tag and Open Graph tags — I want to know if it's ready to share on social media.”
Pre-launch metadata verification
“Before I launch my new blog at https://blog.acmecorp.com, can you check if the SEO title and og:title are present and look correct?”
Link count inspection
“Can you audit https://docs.example.io/getting-started and tell me how many outbound links are on the page and whether the SEO title is set?”
Technical details
Endpoint
GEThttps://webcap.shoutsid.fyi/v1/x402/audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, structured SEO and Open Graph metadata audit for a specific URL without setting up an account or API key. It is ideal for one-off or automated per-page checks in agent workflows that need to verify page readiness for social sharing or search indexing. It is not suited for full site crawls, screenshot capture, or deep content extraction.
Side effects
- Invalid or unreachable URL returns an error or empty audit fields
- Private/localhost URLs may be blocked or return no data
- Pages behind authentication walls may not be fully audited
- Payment failure results in 402 response before audit is performed
- Very slow pages may time out before metadata is extracted
