We present easy-to-use web applications and Web Services to search, plot and manage spectral energy distributions and filter profiles. We provide keyword search, advanced query forms and SQL interfaces to select spectra or band passes that may be retrieved in a variety of formats including XML, VOTable and ASCII.

All SDSS DR1 spectra had been loaded into a database as well as the entire 2dF catalog that adds up to more than half million SEDs but registered users can upload their own data making it available for the rest of the community and are free to modify or delete them at any time. Scientific services allow to build rest-frame composite spectra out of selected spectra.

The band pass database has a growing collection of photometric filters and the same search interfaces. Using the spectrum and filter profile core services, we plan to build higher level services to help astronomers create color-color diagrams, simulated catalogs and estimate distances to extragalactic objects.
