Use the web-tool to check whether a paper has been retracted.

To query the API, simply GET http://openretractions.com/api/doi/${doi}/data.json.

e.g.:

curl http://openretractions.com/api/doi/10.1002/job.1787/data.json

If the paper has no recorded update in the database, the API will return a 404 (not found) error.

If there's a recorded update, the API will return a JSON object.

If the paper was retracted, the retracted field will be true. If the field is false, it means a non-retraction update to the paper was recorded by the publisher. This could be:

• a correction or erratum
• an expression of concern
• a withdrawal

In some cases, publishers mis-label retractions as other updates. It is therefore best to follow the update link to check the full statement about any update.

Here's an example JSON response that shows the full format:

{
  "retracted": false,  // whether or not the paper has been retracted
  "timestamp": 1361836800000, // the UNIXtime when the original paper was published
  "update": {
    "timestamp": 1491464002919, // the UNIXtime when the update was recorded
    "doi": "10.1002/job.1858", // the DOI of the update
    "type": "correction" // the publisher's description of the update
  },
  "doi": "10.1002/job.1787", // the DOI of the original paper
  "journal": "Journal of Organizational Behavior",
  "publisher": "Wiley-Blackwell",
  "title": "Erratum: Cognitive and affective identification: Exploring the links between different forms of social identification and personality with work attitudes and behavior"
}

• The data currently comes from:
  • the PubMed API, using bionode-ncbi
  • the CrossRef API, using crossref-retractions
• We use jq by @stedolan a lot for manipulating streams of JSON data.
