The ALeRCE broker is a Chilean-led broker which is processing the alert stream from the Zwicky Transient Facility (ZTF) and which aims to become a Community Broker for the Vera C. Rubin Observatory and its Legacy Survey of Space and Time (LSST), as well as other large etendue survey telescopes. We are using Cloud Infrastructure and Machine Learning models to bring real-time processed products and services to the astronomical community.
A collection of jupyter notebooks and scripts on how to access the ALeRCE database, API, etc; https://github.com/alercebroker/usecases
MARS provides access to all public alerts issued by ZTF since the start of the public alert stream on June 1, 2018. Subsets of the alerts, filtered by selectable constraints, may be identified and downloaded, either through this webpage or using the underlying API. Alerts are ingested as they are generated by the ZTF survey and are made available immediately
Lasair is a broker for astronomers studying transient and variable astrophysical sources.
Flares of known astronomical sources and new transient phenomena occur on different timescales, from sub-seconds to several days or weeks. The discovery potential of both serendipitous observations and multi-messenger and multi-wavelength follow-up observations could be maximized with a tool which allows for quickly acquiring an overview over both persistent sources as well as transient events in the relevant phase space. ASTRO-Colibri tries to do this.
Asteroid Terrestrial-impact Last Alert System (ATLAS) is an asteroid impact early warning system being developed by the University of Hawaii and funded by NASA. It consists of two telescopes, 100 miles apart, which currently surveys the whole visible sky north of -50 degrees every 2 nights.
There is now a forced photometry server, which provides full public access to photometric measurements over the full history of ATLAS survey.

SpecFit is an [R] based package which allows users to display, edit and analyse 1D spectra. A spectrum is uploaded using a user-defined set of paramerters and then be displayed in various ways using multiple options. SpecFit allows the user to measure emission and absorption line fluxes, and manually and automatically assign redshift. Spectra and line fit tables can then be saved in various formats.

MAXI hard X-ray data can be searched by RA and DEC. Not sure how trust worth it is though.
Here you can perform single object, multi object or all sky search for WISE data using RA and DEC:
