How this service works
Has this paper been retracted, corrected or flagged? Notices from Crossref and Retraction Watch for a DOI.
Output
Returns a structured response including the paper's DOI, a verdict (e.g. retracted, corrected, clear), a plain-language summary, a list of notices (each with type, date, source, and notice DOI), reasons for any flags, the source URL, an 'asOf' timestamp, and a disclaimer. Also indicates if any sources were not checked and whether the result is degraded.
Example use cases
Citation integrity check before publishing
“Before I submit my manuscript, can you verify whether the paper at DOI 10.1038/nature12345 has been retracted or corrected? I need to make sure my citations are still valid.”
Fact-checking a viral science claim
“A news article is citing a study with DOI 10.1126/science.aab1234 as proof of a breakthrough — can you check if that paper has any retraction notices or corrections I should know about?”
Systematic review screening for retracted studies
“I'm doing a literature review and need to screen this paper: DOI 10.1001/jama.2021.1234. Has it been retracted, flagged by Retraction Watch, or issued any corrections?”
Technical details
Endpoint
GEThttps://research-papers.x402tookit.com/paper-retraction-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a definitive, sourced integrity check on a specific paper before citing it, fact-checking a claim, or screening a literature review. Prefer this over manual Crossref or Retraction Watch searches when you need a combined, structured verdict in a single API call. Most useful for agents doing automated citation validation, academic writing assistance, or research integrity workflows.
Side effects
- Invalid or malformed DOI returns an error or null result
- DOI not found in Crossref or Retraction Watch returns a 'not found' or inconclusive verdict
- Degraded mode if one data source (e.g. Retraction Watch) is unavailable — partial results with 'degraded: true'
- Rate limiting or payment failure returns a 402 or 429 error
- Very recent retractions may not yet be indexed, leading to a false-clear result
