 ## Public vs Member API
 
-ORCID provides two different API endpoints for the ORCID Public API and the ORCID Member API.
+ORCID provides two different API endpoints: the ORCID Public API and the ORCID Member API.
 
-The **Public API** is free and available to anyone. It allows for ORCID iD authentication and reading public data from ORCID records. It allows the journal to have contributors' ORCID iDs authenticated and displayed on article/preprint pages. Its main difference from the Member API is that it will not automatically send publication details to a contributor’s ORCID record upon publication. If you start with the Public API and then later decide to switch to the Member API, please contact ORCID support to coordinate the transition from Public to Member API.

-If your journal is affiliated with an institution, contact the institution's library to ask about ORCID membership and API credentials. You can also consult the ORCID member directory to see if your organization is already an [ORCID member](https://orcid.org/members), or review [ORCID’s membership information](https://orcid.org/about/membership) if your organization is interested in becoming an ORCID member. You can also contact ORCID directly at support@orcid.org.
