PEPs API

There is a read-only JSON document of every published PEP available at https://peps.python.org/api/peps.json.

Each PEP is represented as a JSON object, keyed by the PEP number. The structure of each JSON object is as follows:

{
  "<PEP number>": {
    "number": integer,  // always identical to <PEP number>
    "title": string,
    "authors": string,
    "discussions_to": string | null,
    "status": "Accepted" | "Active" | "Deferred" | "Draft" | "Final" | "Provisional" | "Rejected" | "Superseded" | "Withdrawn",
    "type": "Informational" | "Process" | "Standards Track",
    "topic": "governance" | "packaging" | "release" | "typing" | "",
    "created": string,
    "python_version": string | null,
    "post_history": string,
    "resolution": string | null,
    "requires": string | null,
    "replaces": string | null,
    "superseded_by": string | null,
    "author_names": Array<string>,
    "url": string
  },
}

Date values are formatted as DD-MMM-YYYY, and multiple dates are combined in a comma-separated list.

A selection of example PEPs are shown here, illustrating some of the possible values for each field:
