How this service works
Website hosted for free through pinggy.io> <meta name=
Output
Returns the verified URL, a receipt object confirming the verification was performed, a 'supported' string indicating whether the page content supports the claim, and an array of cross-reference objects linking related evidence found on the page.
Example use cases
Fact-checking a news article claim
“I saw an article at https://bbc.com/news/climate-article claiming 'global temperatures rose 1.2°C since 1900' — can you verify that claim against the actual page content and tell me if it checks out?”
Validating a product page statement
“Check whether this product page at https://shop.example.com/product/123 actually states that the item has a 5-year warranty — I want a verification receipt I can rely on.”
Confirming research citation accuracy
“I need to verify that https://ncbi.nlm.nih.gov/pmc/articles/PMC1234567 supports the claim that 'vitamin D deficiency is linked to increased COVID-19 severity' — can you run a content verification on it?”

Endpoint
POSThttps://jhkvo-159-89-4-32.free.pinggy.net/verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a paid, receipted verification of a URL's content against a specific claim — particularly when you need a verifiable audit trail (receipt object) of the fact-check. Useful for agents that must document their research process or need cross-references returned alongside a support verdict.
Side effects
- URL is unreachable or returns a non-200 HTTP status — verification cannot proceed
- Page content is behind a login or paywall — content cannot be read
- Claim field is ambiguous or too vague for meaningful content matching
- URL resolves to a blank or JavaScript-rendered page with no accessible text content
- Pinggy.io free hosting service may be temporarily unavailable causing endpoint downtime
