# Python PEPs Brief Digest

> Python PEPs Brief Digest is a paid API for AI agents from oracles-production.up.railway.app, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-15).

Returns an LLM-generated digest summarizing the most consequential recent Python Enhancement Proposals (PEPs) within a configurable time window.

## Facts

- Endpoint: GET https://oracles-production.up.railway.app/v1/python-peps/brief
- Price: $0.25/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability python-peps-brief-digest-29ee7295
```

Example prompt: Give me an AI-written digest of the most consequential Python PEPs from the last 30 days so I can catch up on what's changed in the language.

## When to prefer this

Use this endpoint when you need a human-readable, AI-curated narrative summary of recent Python PEPs rather than raw proposal data. It is ideal for developers or teams wanting a quick briefing on consequential Python language changes without parsing raw PEP documents themselves. Prefer this over raw PEP feeds when a concise digest for a non-expert audience is needed.

## Known failure modes

- No PEP changes found in the requested window — may return an empty or minimal brief
- Invalid date-time format for 'since' parameter — returns a 400 error
- LLM generation failure — may fall back to template-based output (generatedBy: template)
- Payment not processed — 402 response requiring $0.25 USDC via x402 protocol

## How this service works

An LLM-written digest of the most consequential recent Python proposals.

## Output

Returns a JSON object containing a 'brief' field with an LLM-written narrative digest of the most important Python PEPs in the window, a 'generatedBy' field indicating whether it was written by an LLM or a template, and a 'basedOnChanges' integer count of how many PEP changes were analyzed.
