Retrieve Pubmed IDs via API

[Bubblbu]

I am matching unstructured references to retrieve DOIs (which is related to #456).

However, I would like to access the results programmatically. I've used the bibliometric queries with the API to access matched objects including their scores which I could probably already work with to retrieve DOIs.

However, my question was about the returned PMIDs in the simpleTextQuery tool. The tool seems to return more Pubmed IDs than is available through the alternative-id field in the API results. I've also looked into the ID converter tools provided by the NCBI to get from DOIs to PMIDs, however, their data seems to be incomplete (although the web interface does return DOI + PMID).

Is there any way to access the same information (unstructured reference -> DOI + Pubmed ID) through an API endpoint?
