JMESPath

JMESPath (pronounced 'james path') is a query language for JSON that allows you to declaratively extract, filter, and transform elements from JSON documents or Python dictionaries. Current stable version is 1.0.0 (1.1.0 on PyPI as of 2026). The project is mature and low-churn — it reached 1.0 in 2022 with no breaking API changes, and releases are infrequent. It is a foundational dependency of boto3/botocore and is used by the AWS CLI --query flag.
