How this service works
Website hosted for free through pinggy.io> <meta name=
Output
Returns a JSON object containing the original URL, a support status string indicating whether the page supports the claim, an array of cross-reference objects with corroborating or contradicting evidence found on the page, and a payment receipt object confirming the transaction.
Example use cases
Fact-checking a news article claim
“Check if this news article at https://bbc.com/news/science-123456 actually supports the claim that 'global temperatures rose by 1.5 degrees Celsius in 2023'.”
Validating a product page statement
“Verify that https://acme.com/product/widget says the product has a 5-year warranty — I want to confirm before I reference it in my report.”
Research citation verification
“Can you check whether https://research.org/study-42 contains evidence supporting the claim that 'sleep deprivation increases accident risk by 70%'?”

Endpoint
POSThttps://ouhue-37-255-229-96.run.pinggy-free.link/verify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify whether a specific URL's content supports or contradicts a particular claim, especially for fact-checking, citation validation, or content auditing workflows. It is distinct from general web scraping because it returns structured cross-reference evidence and an explicit support verdict tied to a claim.
Side effects
- URL is unreachable or returns a non-200 status — endpoint may return an error or empty cross-references
- Paywalled or JavaScript-heavy pages may not render properly, resulting in incomplete content analysis
- Ambiguous or very broad claims may return low-confidence or inconclusive support status
- Invalid URL format in the request body causes a validation error
- Rate limiting or network timeouts from the target website may cause verification failure
