Hi @sckott, once the click-through service is deprecated there will not be a Crossref API key to request full text. We won’t be retaining that role as an intermediary.
So, the way that will work for researchers is:
To use Crossref’s metadata services to perform TDM, researchers should have a list of DOIs for the content they want to download, and a whitelist of licenses that they accept. Researchers can get a list of DOIs from citations, our metadata search, our metadata API, or another source.
For each DOI, researchers should:
- Use content negotiation to get the metadata for the DOI
- Check to see if the DOI has license and full-text details in its metadata
- Check the license against your whitelist of acceptable licenses
- If you agree to the license, follow the link and download the full-text of the content item.
Does that answer your question?
