How this service works
Website hosted for free through pinggy.io> <meta name=
Output
Returns the verified URL, a payment receipt object, a 'supported' string indicating whether the page content supports the optional claim, and an array of cross-reference objects found on or related to the page.
Example use cases
Fact-checking a news article claim
“I saw someone claim that 'the unemployment rate dropped to 3.4% in January 2023' and linked to this article: https://www.bls.gov/news.release/empsit.nr0.htm — can you verify if the page actually supports that claim?”
Validating a product claim on a vendor site
“Can you check whether https://vendor-site.com/product-specs actually states that the battery life is 48 hours? I want to know if the page supports that claim before I quote it to a customer.”
Cross-referencing a cited source
“Someone cited https://research-journal.org/article/123 to back up the claim that 'coffee reduces risk of type 2 diabetes' — can you verify if the page really supports that and pull any cross-references?”
Technical details
Endpoint
POSThttps://eymqg-159-89-4-32.run.pinggy-free.link/verifyWhen to prefer
Choose this endpoint when you need to verify whether a specific web page actually supports a stated claim, or when you need cross-references extracted from a page to fact-check information. Prefer it over generic web scraping when the goal is claim validation with a structured supported/not-supported verdict rather than raw content extraction.
Side effects
- URL is unreachable or returns a non-200 status — verification cannot proceed
- Page content is behind a login wall or paywall — content inaccessible for analysis
- Claim is ambiguous or too vague to match against page content — 'supported' may be inconclusive
- URL returns dynamic JavaScript-rendered content that cannot be parsed — incomplete analysis
- Invalid URL format in input — request rejected
