The fine print

License note: Custom: PEP 1 requires new PEPs to be public domain and CC0-1.0-Universal; older PEPs carry their own public-domain statements. The JSON names PEP authors as public authorship. Signal Lab links only.
Required attribution: Not required; citing peps.python.org is good practice.

Verdict

A Python governance source, alongside pypi-json-api. Licence: Custom: PEP 1 says "Each new PEP must be placed under a dual license of public domain and CC0-1.0-Universal"; older PEPs carry their own public-domain statements, so no single licence id covers every record. The PSF legal page contains no ban on automated access. Rate limits: Not stated. Signal Lab links only.
