AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Adds AWS Signature Version 4 authentication to Python requests, enabling authenticated calls to AWS services including S3, DynamoDB, Lambda, and others that support AWS auth v4.

Low friction: pure Python wheel with only requests as a runtime dependency. Active maintenance with recent release (104 days ago) and ongoing repository activity. Supports Python 3.7–3.12.

MIT License (permissive): you may use, modify, and distribute this package freely in commercial and private projects, with minimal restrictions beyond attribution.

Usage

pip install requests-aws4auth

import requests
from requests_aws4auth import AWS4Auth

auth = AWS4Auth('<ACCESS_ID>', '<ACCESS_KEY>', 'us-east-1', 's3')
response = requests.get('https://s3.amazonaws.com/', auth=auth)

Requires Python 3.7 or later; AWS credentials (access ID and key) must be available at runtime.

Verdict: Production-ready, actively maintained package for AWS authentication in requests. No known vulnerabilities, permissive MIT license, and minimal dependencies make it a safe choice for applications needing AWS API access. Well-suited for long-running services via optional botocore RefreshableCredentials integration.
