Async frameworks (aiohttp) incompatible due to blocking HTTP calls #5

Async frameworks (aiohttp) incompatible due to blocking HTTP calls

Description
The SDK uses blocking I/O, making it unsuitable for async frameworks like aiohttp.

Code snippet

import aiohttp
from openapi_sdk import Client

async def fetch():
    client = Client("token")
    return client.request("GET", base_url, "/advance")

Observed behavior
Blocks event loop.

Expected behavior
Async-compatible client or aiohttp support.
