Study of the Skyportal API

[camilledzt]

In order to create the corpus for the project, a study of the Skyportal API is needed to know which data we can include in the corpus.
The API documentation is here: https://skyportal.io/docs/api.html

What was done:

Reviewed the SkyPortal API documentation and selected the endpoints that seemed most relevant for corpus construction.

Tested 69 API endpoints to check accessibility with our token, response structure, available fields, skipped endpoints, non-JSON responses and timeouts.

Identified /api/sources as the main inventory endpoint because it supports many useful filters.

Created complete filtered inventories for:

sources with spectra;
sources with follow-up requests;
classified sources;
sources with redshift;
sources with at least 5 detections;
GCN-like sources;
EP-like sources.
Organized the raw local outputs under data/raw/skyportal/.

Added documentation explaining how to reproduce the workflow and why the main decisions were made.

Documentation added:
