Tools

• check_prop65

  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.

• describe_prop65_list

  Report the size and edition of the embedded Proposition 65 list, and what the listing-mechanism codes mean. Use this to check how current the data is before relying on a lookup, or to interpret the `AB`, `SQE`, `FR` and `LC` codes on an entry. Returns counts of total, active and delisted entries, how many carry a CAS number, and the edition date. It reports on the data only and cannot tell you whether any product requires a warning.

  shallow
• list_recent_listings

  List the chemicals added to Proposition 65 on or after a given year. Use this to find recent additions, which matters because a warning is generally required twelve months after a chemical is listed, so a new entry starts a compliance clock. Returns active listings only, newest first, with their dates, and reports how many entries carry no parseable date and are therefore missing from the answer. It does not tell you whether any particular product is affected.

  shallow
• search_prop65

  Search the Proposition 65 list for chemicals whose name contains a fragment. Use this when you do not have an exact name or a CAS number, or to survey a family of related substances. Returns matching chemicals with their CAS numbers, toxicity endpoints, listing dates and delisted flags, capped at a limit with `truncated` set when there were more. It searches names only, so it will not find a chemical listed under a synonym you did not search for, and a result here is not a determination that a warning is required.
