Search one MS/MS spectrum against all public GNPS/MassIVE data (or the GNPS libraries) with fastMASST. Give a USI, pick a library, and get the matching public spectra and which datasets they came from — the search runs on the GNPS server, the rest in your browser.

fastMASST matches fragmentation patterns; a hit means a public spectrum looks
similar to your query, not a confirmed identification — verify with the
mirror plot and metadata. “All public data” searches GNPS/MassIVE repository
spectra; annotations (compound names) come only from library hits. Search runs
on api.fasst.gnps2.org; this page needs cross-origin access enabled
there for apps.gnps2.org, else the search fails with a network error.
