How this service works
Website hosted for free through pinggy.io> <meta name=
Output
Returns an object containing the verified URL, a receipt object (likely a payment or verification receipt), a 'supported' string indicating whether the page content supports the given claim, and an array of cross-reference objects linking related evidence or sources.
Example use cases
Fact-checking a published article
“Check if the page at https://news-site.com/story/climate-data actually supports the claim that 'global temperatures rose by 1.5 degrees last year' — I want to know if the content backs that up.”
Validating a product claim
“Can you verify that the URL https://shop.example.com/product/solar-panel actually contains the claim that it has a 25-year warranty? I need cross-references confirming it.”
Auditing a reference link
“I have a citation pointing to https://research.org/study/water-quality — please verify the page is accessible and check if it supports the claim that 'municipal water lead levels exceed safe limits in 30% of US cities'.”

POSThttps://btolb-159-89-4-32.free.pinggy.net/verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify whether a specific URL's content actually supports a stated claim or assertion, especially for fact-checking, citation auditing, or content validation workflows. It is distinct from general web scraping because it returns a structured 'supported' verdict and cross-references rather than raw content. Prefer it over manual review when you need a programmatic, auditable verification receipt.
Side effects
- URL is unreachable or returns a non-200 HTTP status — verification cannot proceed
- Page content is behind a login or paywall — claim cannot be validated
- Claim field is ambiguous or too broad — 'supported' result may be inconclusive
- URL points to non-text content (e.g. PDF, video) — parsing may fail
- Pinggy.io free hosting may cause intermittent downtime or connection timeouts
- Rate limiting or payment failure at $0.25 per call may interrupt batch usage
