Returns a result object containing verification status and response data indicating whether the submitted paper or document input is valid and authentic, along with a status string confirming success or failure of the verification request.
Example use cases
Academic citation authenticity check
“I found a paper titled 'Deep Learning for Medical Imaging' and want to make sure it's a real published paper before I cite it in my thesis — can you verify it?”
Preprint legitimacy validation
“There's an arXiv preprint I'm about to share with my team — can you check if '2301.00234' is a verified and authentic paper?”
Research fraud detection
“Someone sent me a reference to a paper claiming it proves X — can you verify whether this paper actually exists and is legitimate?”
Technical details
Endpoint
POSThttps://whatchuneed.vercel.app/api/verify/papers?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call paper or document verification without maintaining a subscription, especially in automated research pipelines or agent workflows that occasionally need to authenticate academic sources. Prefer this over manual database lookups when programmatic verification is needed at scale.

- Missing or empty input string returns validation error
- Unrecognized paper reference may return unverified status
- Malformed request body without required 'input' field returns 400
- Downstream verification service unavailability may cause timeout or error status
- Ambiguous paper identifiers may return inconclusive results
