OSF Identifiers API is one of 41 APIs that [OSF](https://apis.io/providers/osf/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Identifiers. The published artifact set on APIs.io includes an OpenAPI specification.

Identifiers are unique strings associated with various entities in the OSF system, such as project nodes, registrations or preprints. Identifiers serve as a means to distinctly reference these entities using standardized formats like DOI (Digital Object Identifier). Each identifier is linked to a specific entity, providing a persistent and resolvable URL that can be used for citation, sharing, and retrieval purposes. Identifiers play a crucial role in ensuring that entities within the OSF ecosystem can be reliably accessed and referenced across different platforms and services. By adhering to widely recognized standards, identifiers facilitate interoperability and integration with external systems, enhancing the visibility and accessibility of research outputs. The Identifiers system allows users to access both Datacite and Crossref for DOI minting services and stores detailed metadata about each identifier, including its category, value, and the entity it is associated with. This ensures that users can effectively manage and utilize identifiers in their research workflows, promoting transparency and traceability of scholarly work.
