The Crossref documentation has lots of information about working with the open API a number of examples of simple requests that you can see here: https://www.crossref.org/documentation/retrieve-metadata/rest-api/a-non-technical-introduction-to-our-api/

> Crossref ... DOI data is openly available,

  ok, if this is true, show me a script that will give me a list of
  all CrossRef DOIs added or modified yesterday, with their associated
  metadata, usable without being a CrossRef member. I don't think it
  can be done, but of course I could be wrong.

> ORCID also has a public API:

  That's othogonal to the question of openness. An API access does not
  make data open. In fact, APIs are often deployed for partial access
  to data.

  The idea that CrossRef and ORCID data is open is a widely-held myth.
