mosir-sdk-python 0.1.3

Python SDK for the Mosir public GraphQL API

mosir-sdk-python

Python SDK for the Mosir public GraphQL API.

What this SDK provides

• generated operation registry from public.operations.graphql
• dynamic snake_case operation methods (query, mutation, subscription)
• optional Bearer token auth
• default endpoint: https://beta.mosir.app/api/v1
• SSE subscription support out of the box
• raw GraphQL access for developers who want direct control

Transport choice

This SDK uses:

• httpx for queries and mutations
• httpx-sse for subscriptions

This keeps the package small while still supporting the preferred subscription transport. WebSocket support is intentionally not bundled. If you want WebSocket subscriptions, use your own GraphQL/WebSocket client.

Install

pip install mosir-sdk-python

or:

uv add mosir-sdk-python

Quick start

Anonymous/public requests

Only public data needs no token.

import asyncio

from mosir_sdk import AsyncMosirClient


async def main() -> None:
    async with AsyncMosirClient() as client:
        post = await client.get_post(post_id="VLO8u7UXqclQ7byjfMEX0")
        print(post["getPost"]["content"])


asyncio.run(main())

Authenticated requests

Use a token for authenticated operations such as notifications.

import asyncio
import os

from mosir_sdk import AsyncMosirClient


async def main() -> None:
    async with AsyncMosirClient(token=os.getenv("MOSIR_API_TOKEN")) as client:
        notifications = await client.get_notifications(limit=20)
        print(notifications["getNotifications"]["edges"])


asyncio.run(main())

Custom endpoint

from mosir_sdk import AsyncMosirClient

client = AsyncMosirClient(
    token="YOUR_TOKEN",
    endpoint="https://example.com/api/v1",
)

Common usage examples

Get a post

import asyncio

from mosir_sdk import AsyncMosirClient


async def main() -> None:
    async with AsyncMosirClient() as client:
        post = await client.get_post(post_id="VLO8u7UXqclQ7byjfMEX0")
        print(post["getPost"]["author"]["username"])
        print(post["getPost"]["content"])


asyncio.run(main())

Get replies under a post

Replies are exposed as nested GraphQL fields on Post, so this is a good case for direct GraphQL usage:

import asyncio

from mosir_sdk import AsyncMosirClient


async def main() -> None:
    async with AsyncMosirClient() as client:
        replies = await client.request(
            """
            query GetPostReplies($postId: ID!, $limit: Int) {
              getPost(postId: $postId) {
                id
                commentsRecent(limit: $limit) {
                  edges {
                    id
                    content
                    createdAt
                    author {
                      id
                      username
                      displayName
                    }
                  }
                  pageInfo {
                    endCursor
                    hasNextPage
                    totalCount
                  }
                }
              }
            }
            """,
            {
                "postId": "VLO8u7UXqclQ7byjfMEX0",
                "limit": 3,
            },
        )

        print(replies["getPost"]["commentsRecent"]["edges"])


asyncio.run(main())

Get notifications

import asyncio
import os

from mosir_sdk import AsyncMosirClient


async def main() -> None:
    async with AsyncMosirClient(token=os.getenv("MOSIR_API_TOKEN")) as client:
        notifications = await client.get_notifications(limit=20)
        print(notifications["getNotifications"]["edges"])


asyncio.run(main())

Fetch media bytes from a Media result

import asyncio

from mosir_sdk import AsyncMosirClient


async def main() -> None:
    async with AsyncMosirClient() as client:
        post = await client.get_post(post_id="VLO8u7UXqclQ7byjfMEX0")
        media = post["getPost"]["attachments"][0]["media"]
        media_bytes = await client.fetch_media(media)
        print(len(media_bytes))


asyncio.run(main())

Fetch preview image for a post, profile, or collection

import asyncio

from mosir_sdk import AsyncMosirClient


async def main() -> None:
    async with AsyncMosirClient() as client:
        preview_url = client.get_preview_image_url("post", "VLO8u7UXqclQ7byjfMEX0")
        print(preview_url)

        preview_bytes = await client.fetch_preview_image("post", "VLO8u7UXqclQ7byjfMEX0")
        print(len(preview_bytes))


asyncio.run(main())

SSE subscriptions

Subscriptions let your app receive updates from Mosir in near real time without polling. This SDK uses SSE (Server-Sent Events) for subscriptions by default.

A good example is a Discord bot:

• subscribe to post_created_by_author
• when a creator publishes something new, format it
• send a message into a Discord channel

That way the bot reacts as soon as something changes, instead of repeatedly calling the API every few seconds. SSE is especially useful for backend workers, bots, notification relays, and other long-running processes that want a simple one-way stream of events from the server. For public subscriptions like post_created_by_author, a token is not required.

Note: each SSE connection lasts at most 1 hour. In practice, network conditions may cause it to end earlier. If you build a bot, worker, or relay process, make sure you implement reconnect logic.

import asyncio

from mosir_sdk import AsyncMosirClient


async def main() -> None:
    async with AsyncMosirClient() as client:
        profile = await client.get_account_profile(username="leemiyinghao")
        author_id = profile["getAccountProfile"]["id"]

        async for event in client.post_created_by_author(
            author_id=author_id,
            post_type="POST",
        ):
            print(event["postCreatedByAuthor"]["id"])
            print(event["postCreatedByAuthor"]["content"])


asyncio.run(main())

You can also use the lower-level operation subscription API:

stream = client.subscribe_operation(
    "post_created_by_author",
    author_id=author_id,
    post_type="POST",
)

Raw GraphQL access

Authentication is optional. Pass token for authenticated operations, or omit it when accessing only public data.

Operation usage

data = await client.operation("get_notifications", limit=20)

Raw GraphQL string usage

replies = await client.request(
    """
    query GetPostReplies($postId: ID!, $limit: Int) {
      getPost(postId: $postId) {
        id
        commentsRecent(limit: $limit) {
          edges {
            id
            content
            createdAt
            author {
              username
              displayName
            }
          }
        }
      }
    }
    """,
    {
        "postId": "VLO8u7UXqclQ7byjfMEX0",
        "limit": 3,
    },
)

WebSocket usage

WebSocket transport is not bundled. If you want it, use your own GraphQL WebSocket client against the same endpoint.

Notes

• default endpoint: https://beta.mosir.app/api/v1
• token is optional for public data and required only for authenticated operations
• the same applies to subscriptions: public subscription data does not require a token
• snake_case methods are resolved dynamically from the operation registry
• media helpers are available through select_media_file(...) and fetch_media(...)
• preview image helpers are available through get_preview_image_url(...) and fetch_preview_image(...)
• subscriptions use SSE in this SDK
• direct GraphQL usage is supported through operation(...), request(...), subscribe_operation(...), and subscribe(...)
