The Weizmann Interactive Supernova Data Repository (WISeREP) serves as an archive of SN spectra and photometry, including both historical (legacy) data and data that are accumulated by ongoing modern surveys and programs. The archive provides information about objects, their spectra, photometry and related metadata.
Here you can perform single object, multi object or all sky search for WISE data using RA and DEC: https://irsa.ipac.caltech.edu/cgi-bin/Gator/nph-dd?catalog=allsky_4band_p3as_psd&mode=html
Covers predominantly data from past and present X-ray instrumentation but does also include other sources of data

This repository provides the FITS files containing high-level MAGIC published results. This includes skymaps of different quantities, 1-D histograms, spectra, light curves and, in general, any set of MAGIC data included in published papers.
The Gravitational-Wave Candidate Event Database (GraceDB) is a service operated by the LIGO Scientific Collaboration. It provides a centralized location for aggregating and retrieving information about candidate gravitational-wave events. GraceDB provides an API for programmatic access, and a client package is available for interacting with the API.
The Treasure Map is designed to help coordinate electromagnetic followup of gravitational-wave (GW) events. It allows observers to easily report their planned and executed observations in search of counterparts to GW events, and to query the reports of other observers, in a programatic way. The goal is to enable coordination between observatories in order to minimize unnecessary overlap in these searches and find the counterpart as quickly and as efficiently as possible.
ATOMDB is an atomic database useful for X-ray plasma spectral modeling. The current version of ATOMDB is primarly used for modeing collisional plasmas, those where hot electrons colliding with astrophysically abundant elements and ions create X-ray emission. However, ATOMDB is also useful when modeling absorption by elements and ions or even photoionized plasmas, where X-ray photons (often from a simple power-law source) interacting with elements and ions create complex spectra.
