What Open Alex Research API does

OpenAlex is an open catalog of scholarly research that indexes works along with their authors, institutions, sources and topics, so the metadata can be searched, analyzed and reused.

Every account gets $1 of usage a day free, with prepaid credit available from $1 beyond that daily amount. An annual subscription is offered as an alternative to prepaid usage, and a PDF sync add-on can be added to a plan.
