SPICA Atlas Projects.json API

The SPICA single-cell / spatial atlas project listing, on UNIL's own host spica.unil.ch. Anonymous open read, confirmed 200 on 2026-09-01. SPICA is UNIL-built and UNIL-run; the host, the application and the data are all the institution's, which makes it the clearest institution-operated contract in this repository. The OpenAPI was reconstructed by API Evangelist from https://spica.unil.ch/home/api and confirmed against live responses — UNIL publishes no machine-readable contract of its own.
