check_prop65
shallowdev.toolstop/prop65 · Verify this server
Look up a chemical by CAS number or name and report whether it is on California's Proposition 65 list. Use this when deciding whether a product sold into California needs a warning label. Returns every matching entry with the toxicity endpoint, the listing mechanism, the date listed and the safe-harbour level where one has been adopted, plus whether the entry has since been delisted. A `not_found` result does not mean the chemical is safe or unregulated: it means this edition of this one list has no entry under that name or number.
