modmux 0.1.1

Single interface for several game mod portals

ModMux

Unified async client for multiple game mod platforms. ModMux normalises provider responses into shared Pydantic models and ships a small CLI for quick lookups.

Features

• Async HTTP client with rate limiting and retry handling
• Normalised Mod metadata model across providers
• Pluggable provider registry
• CLI for fetching a single mod and printing JSON

Supported providers

• Modrinth
• CurseForge
• Nexus Mods
• mod.io
• Steam Workshop
• Factorio Mod Portal (Wube)

Requirements

• Python 3.13+
• Dependencies: pydantic, httpx, aiolimiter

Install

From the repo:

python -m pip install -e .

CLI usage

The CLI expects a provider name and provider-specific mod id. Provider names are case-insensitive.

modmux MODRINTH fabric-api --pretty
modmux CURSEFORGE 238222 --pretty
modmux NEXUSMODS 12345 --game transportfever2
modmux MODIO some-mod --game 4321 --user 12345 --token <api-key>

Or without installing a script:

python -m modmux MODRINTH fabric-api --pretty

Output is a JSON serialisation of the Mod model.

Credentials and environment variables

• --token accepts API tokens/keys.
• --user supplies a user id for providers that need user-scoped base URLs (mod.io).
• Environment variables:
  • MODMUX_TOKEN (fallback for all providers)
  • MODMUX_<PROVIDER>_TOKEN (provider-specific, e.g. MODMUX_MODRINTH_TOKEN)
  • MODMUX_<PROVIDER>_USER (provider-specific user id, e.g. MODMUX_MODIO_USER)

Library usage

Two supported patterns are available: an async context manager or a manually closed client.

import asyncio

from modmux import ModID, Muxer, Provider

mod_id = ModID(provider=Provider.MODRINTH, id="fabric-api")


async def run() -> None:
    async with Muxer(creds={Provider.MODRINTH: {"token": "token"}}) as mux:
        mod = await mux.get_mod(Provider.MODRINTH, mod_id)
    print(mod.name)


asyncio.run(run())

import asyncio

from modmux import ModID, Muxer, Provider

mod_id = ModID(provider=Provider.MODRINTH, id="fabric-api")


async def run() -> None:
    mux = Muxer()
    try:
        mod = await mux.get_mod(Provider.MODRINTH, mod_id)
    finally:
        await mux.aclose()
    print(mod.name)


asyncio.run(run())

The modmux_client(...) helper remains available as a convenience wrapper around Muxer for existing code.

Provider notes

• CurseForge: slug lookups require ModID.game (game id).
• Nexus Mods: requires ModID.game (game domain, e.g. skyrim).
• mod.io: requires ModID.game plus a user id (use --user or MODMUX_MODIO_USER).
• Steam: uses a Workshop published file id; ModID.game is optional.
• Wube: uses the Factorio mod name slug.
