IRSA Virtual Observatory APIs (Caltech/IPAC) 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 Astronomy, Virtual Observatory, TAP, ADQL, and NASA. The published artifact set on APIs.io includes API documentation.

The NASA/IPAC Infrared Science Archive exposes IVOA-standard Virtual Observatory interfaces — Table Access Protocol (TAP/ADQL), Simple Cone Search and Simple Image Access v2 — over NASA infrared and submillimeter mission catalogs and images. Verified live 2026-08-19: the TAP sync endpoint returned real TAP_SCHEMA rows, and the capabilities document declares VOSI capabilities, availability and tables, DALI examples, and an IVOA SSO cookie security method.
