How this service works
Fetches a URL server-side and checks whether a claim actually appears on the page.
Output
Returns a JSON object with: whether the claim was found (boolean or null if unreachable), a confidence score (0-1), the specific matched snippet from the page, the list of matched terms, the HTTP status of the fetched page, a SHA256 hash of the page content for auditability, and a timestamp of when the check was performed.
Example use cases
Fact-checking a news article claim
“Someone told me that the BBC article at https://bbc.com/news/article-12345 says 'inflation hit a 40-year high' — can you verify whether that exact phrase actually appears on that page?”
Compliance text audit on a vendor site
“We need to confirm our vendor's privacy policy at https://vendorcorp.com/privacy actually includes the phrase 'GDPR compliant data processing' — can you check that for me?”
Validating a product feature listing
“Before we finalize the contract, can you verify that https://softwarevendor.com/pricing actually mentions 'unlimited API calls' on the page?”
Technical details
Endpoint
POSThttps://verify.v2w.com.br/v1/verifyWhen to prefer
Choose this endpoint when you need server-side, auditable verification that a specific text claim appears on a live web page — especially for fact-checking, compliance audits, or validating third-party assertions. It is ideal when you need a confidence score and an exact matched snippet as evidence, rather than just a raw page scrape. Prefer this over general scraping tools when the task is specifically about confirming or denying the presence of a claim.
Side effects
- URL is unreachable or returns non-200 HTTP status — 'found' will be null and http_status reflects the error
- Claim not found on page — 'found' returns false with empty matched_terms
- Page requires JavaScript rendering — server-side fetch may miss dynamically loaded content
- Paywalled or login-gated pages — content may not be accessible, returning null or partial results
- Claim is present but phrased differently — low confidence score with partial term matches
