Verdict

A package-metadata source for software inventory work, alongside pypi-json-api. Licence: BSD-2-Clause: the formulae.brew.sh licence file is the "BSD 2-Clause License", "Copyright (c) 2009-present, Homebrew contributors". The JSON lists bottle (binary package) URLs; Signal Lab links the metadata only, never binaries. No website terms with an automated-access ban were found. Rate limits: Not stated. Signal Lab links only.
