awscurl
Curl like tool with AWS request signing
Decision gist · record as of 2026-08-14
Yes. The package solves a real friction point—making signed AWS API requests from the command line—with low install overhead, active maintenance, no known vulnerabilities, and permissive licensing. It's especially useful for developers who prefer curl-style interfaces or need to integrate AWS calls into shell scripts. The 902 GitHub stars and top-15000 PyPI position indicate established adoption.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires AWS credentials available either as command-line arguments, environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_PROFILE), or in ~/.aws/credentials file.
- Low install friction with a pure Python wheel distribution.
- Active maintenance with a recent release (62 days ago) and steady repository activity.

What it is and what it does
awscurl is a command-line tool that bridges the gap between curl's simplicity and AWS's mandatory request signing requirement. It wraps HTTP requests in AWS Signature Version 4 signing, automatically handling credential lookup from IAM profiles or explicit keys, then sends the signed request to any AWS service endpoint. The tool accepts curl-like arguments (method, headers, data, output redirection) while adding AWS-specific options for region, service, and credential selection.
The package is built on requests for HTTP transport and boto3/botocore for AWS credential and signing logic, making it a thin orchestration layer. It's designed for developers and operators who want to test AWS APIs from the command line without manually constructing signatures—useful for ad-hoc API exploration, scripting, CI/CD pipelines, or debugging API Gateway and other AWS services that require signed requests.
Use it for
- Test AWS API Gateway endpoints or Lambda function URLs from the command line with automatic request signing.
- Query S3 buckets, EC2 instances, or other AWS services directly without writing Python code or using the AWS CLI.
- Automate AWS API calls in shell scripts or CI/CD pipelines where curl-like syntax is more natural than SDK calls.
- Debug signed requests to AWS services by inspecting headers and responses with verbose output.
- Integrate AWS API calls into existing curl-based workflows or monitoring systems.

Before you install
Low install friction with a pure Python wheel distribution. Active maintenance with a recent release (62 days ago) and steady repository activity. Depends on well-established libraries (requests, boto3, botocore, urllib3) that are widely used and stable.
Requires AWS credentials available either as command-line arguments, environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_PROFILE), or in ~/.aws/credentials file.
License in practice
MIT license permits free use, modification, and distribution with minimal restrictions, making it suitable for both open-source and commercial projects.
