longwei 1.4.3

Python client library for ActivityPub-compatible servers

longwei

Longwei is a minimal Python implementation of the ActivityPub client REST API used by Mastodon, Pleroma, GotoSocial, and snac. This implementation makes use of asyncio where appropriate. It is intended to be used as a library by other applications. No standalone functionality is provided.

All targeted Mastodon v1/v2 API endpoints are now implemented, covering accounts, timelines, statuses, notifications, lists, filters, polls, reports, discovery, and instance management. Admin, push notification, and proof endpoints are intentionally out of scope. Longwei is used by Fedinesia, Feed2Fedi, and FenLiu and Zhongli.

Quick start

pip install longwei

import asyncio
import httpx
from longwei import APClient

async def main():
    async with httpx.AsyncClient() as client:
        ap = await APClient.create(
            instance="mastodon.social",
            client=client,
            access_token="your_token",
        )
        status = await ap.post_status("Hello, fediverse!")
        print(status.url)

asyncio.run(main())
