Not that datacite.org only provides DOI metadata for DOIs registered by datacite.org. If search for a DOI registered by another DOI Registration Agency, you will get an error:

curl https://api.datacite.org/dois/10.1037/0003-066x.59.1.29

{"errors":[{"status":"404","title":"The resource you are looking for doesn't exist."}]}
