Batch annotation

Upload a CSV, TSV, Excel, plain text, or SMILES file with SMILES or InChIKey values. Files with or without a header row are accepted; columns are auto-detected. Each input is matched against the corpus by full 27-character InChIKey (exact compound) and by 14-character prefix (stereoisomer family). Matched rows return with license tier, classification, pathway, ADMET context, and taxonomic origin.
