Example use cases
Academic paper citation check
“I'm about to submit my research paper and need to make sure my citations are legitimate — can you verify this reference: 'Johnson, M. (2019). The Economics of Renewable Energy. Journal of Environmental Studies, 12(3), 45-67' and confirm it's accurately quoted?”
News article source validation
“Before I publish this article, verify this citation: 'The WHO stated in 2022 that 2.5 billion people lack access to safe drinking water' — I want to confirm the source is real and the statistic is correctly attributed.”
Fact-checking a disputed claim
“Someone cited a study claiming 'Stanford researchers found that remote work increases productivity by 13%' — can you verify if this citation is accurate and whether it's being represented correctly?”

Endpoint
POSThttps://whatchuneed.vercel.app/api/verify/citations?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate whether citations, references, or quoted claims are accurate and credible before publishing or submitting content. It is particularly useful for academic writing, journalism, and research workflows where citation integrity is critical. Prefer this over general-purpose search when you specifically need a pass/fail or credibility verdict on a citation rather than just finding information about a topic.
Side effects
- Vague or incomplete citation input may return inconclusive results
- Citations to paywalled or inaccessible sources may not be fully verifiable
- Very recent publications may not yet be indexed
- Malformed input string may return an error status
- API may return generic result object with limited detail for ambiguous queries
