## Health v2 (maintenance only)
Score: 67/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 99, release rhythm 8, longevity 100
- inputs: {"age_days": 4352, "days_push": 7, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Boto3 is the official Amazon Web Services SDK for Python, providing idiomatic Python APIs for AWS services such as S3, EC2, and DynamoDB. It is built on botocore, the low-level library shared with the AWS CLI, and handles credentials, retries, pagination, and serialization.

## Use cases
- upload and download files to amazon s3 from python
- manage ec2 instances programmatically
- query dynamodb tables from a python script
- automate aws infrastructure with python
- wait for aws resources to reach a given state
- call any aws service api from python

## When to choose
- you are building Python applications or scripts that interact with AWS services
- you need official, up-to-date coverage of the full AWS API surface
- you want high-level resource APIs plus low-level client control
- you need features like pagination, waiters, and automatic S3 multipart transfers

## When to avoid
- you are targeting clouds other than AWS
- you need a CLI rather than a Python library (use the AWS CLI, which shares botocore)
- you want infrastructure-as-code tooling rather than imperative SDK calls (consider CDK or Terraform)

## Facets
- artifact type: library
- maturity: stable
- function: sdk, http-client, serialization, auth
- domain: cloud-computing, developer-tools, apis
- platform: python, cross-platform
- tags: aws, boto3, botocore, cloud-sdk, amazon-web-services, s3, ec2, dynamodb, automation
