Find Part

find_part

Read-only

Search the bundled parts catalog (offline). For a NEMA-17 motor write await lib.standard.nema17(); for a 608 bearing write await lib.standard.bearing608(). Do not fan out parallel lookups and do not pass partsBaseUrl unless you set source:"remote". Remote lookups fail within 45s with errorCode parts.lookup.timeout instead of hanging.
