Give the GHS hazard classification of a chemical compound by its compound identifier (CID) or by a name: a common, trade or systematic name, or a CAS registry number such as 50-00-0. Returns one classification per classifying source, in the source order: the GHS pictograms with their codes (GHS05), the signal word, the hazard statements with their codes (H314) and the precautionary statement codes. Only two classifying sources are returned: the EU harmonised classification (Regulation (EC) No 1272/2008) and the Hazardous Substances Data Bank of the US National Library of Medicine; every other source is left out, so a compound classified only by others returns an empty list.
classified is true when a returned classification has a hazard statement. A name matching several compounds uses the first and lists them all in matched_cids. compound is null when the name or CID matches nothing, or the source has no classification for the compound. Give exactly one of cid and name. Toxicity values, exposure limits, the full safety data sheet, and any synthesis or preparation data are not returned.
Authentication
Requires x402 payment in thepayment-signature header.
