APIs

[RobSullivan]

Here are some APIs that might be useful for finding links to open access full text articles. I've not yet found one that provides direct access except for Pubmed's full text API, which returns XML. http://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=pmc&id=4046971

Another from http://core.ac.uk/ needs an API key http://core.ac.uk/docs/#!/articles/getArticleByCoreIdBatch

And finally my project 😄 https://pmc-ref.herokuapp.com/ returns the references of an article along with the PMCID if they have one. The format is JSON so it could be processed to extract the PMCIDs and append http://www.ncbi.nlm.nih.gov/pmc/articles/ to each one to get links to full text. Here's the documentation https://github.com/RobSullivan/pmc-ref/wiki
