GNPS Get Spectrum

Retrieve a mass spectrometry (MS/MS) reference spectrum from the GNPS spectral library using a Universal Spectrum Identifier (USI). Returns precursor m/z, charge, number of peaks, m/z range, and the top 20 peaks by intensity. GNPS is the world's largest community-curated spectral library for metabolomics and natural products research. Example: 'mzspec:GNPS:GNPS-LIBRARY:accession:CCMSLIB00005435737' retrieves a reference spectrum with precursor m/z 405.264 and 83 peaks.
