CaltechAUTHORS REST API and OAI-PMH is one of 11 APIs that [California Institute of Technology](https://apis.io/providers/caltech/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Publications, Repository, InvenioRDM, OAI-PMH, and ORCID. The published artifact set on APIs.io includes API documentation.

Caltech's institutional publications repository, also on self-hosted InvenioRDM. Exposes the same REST record API and an OAI-PMH 2.0 endpoint, carrying ORCID and ROR identifiers and Caltech-specific custom fields (journal:journal, caltech:groups, caltech:publication_status). Verified live 2026-08-19. Note: intermittent HTTP 522 (Cloudflare origin unreachable) was observed between successful calls — the surface is live but flapping, and Caltech publishes no status page on which to confirm that.
