# aioopenexchangerates — Fetch rates from openexchangerates with aiohttp.

License: permissive · Maintenance: active · Downloads: 74.4K/mo

## What it is and what it does

aioopenexchangerates is an async wrapper around the Open Exchange Rates API, built on aiohttp for non-blocking HTTP requests. It provides a Client interface to fetch currency exchange rates without blocking your event loop.

The package is designed for developers building async Python applications that need exchange rate data. It handles the HTTP communication and response parsing, letting you focus on your business logic. Being pre-alpha, it is actively developed but not yet at a stable release.

Use it for:

- Fetch exchange rates in async web applications or microservices
- Build currency conversion features into async fintech tools
- Poll exchange rates periodically in background tasks without blocking
- Integrate forex data into async data pipelines or dashboards

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Async client library for fetching currency exchange rates from the Open Exchange Rates API using aiohttp.

Yes, if you need an async Open Exchange Rates client and are comfortable with pre-alpha software. Low install friction, permissive license, and active maintenance make it safe to try. However, verify API key requirements and rate limits with the Open Exchange Rates service before committing to production use.

## Install

pip install aioopenexchangerates
uv add aioopenexchangerates
poetry add aioopenexchangerates

## Installing aioopenexchangerates

Before you install: Low install friction; pure Python wheel with two runtime dependencies (aiohttp and mashumaro). Actively maintained with recent commits; pre-alpha status suggests early-stage maturity.

License in practice: Apache-2.0 permissive license allows commercial and private use with minimal restrictions; suitable for most projects.

Quickstart:

import asyncio
from aioopenexchangerates import Client

async def main():
    async with Client("your_api_key") as client:
        result = await client.get_latest()
        print(result)

asyncio.run(main())

Requires Python 3.13 or later; an active Open Exchange Rates API key is needed to fetch data.

Verify before relying:

- API key requirements and rate limits for Open Exchange Rates service
- Whether the package handles authentication token refresh or expiration
- Supported currency pairs and data freshness guarantees
- Production readiness timeline for moving beyond pre-alpha status
