It extracts and type-converts parameters, headers, cookies, and request bodies according to the schema, raising an error if the data does not conform. The library works both client-side (validating responses from external APIs) and server-side (validating incoming requests), and includes built-in integrations with Requests, Werkzeug, Django, Flask, FastAPI, Starlette, Falcon, and AIOHTTP.\n\nThe package depends on jsonschema, openapi-schema-validator, and openapi-spec-validator to perform the actual validation logic. It is actively maintained, supports modern Python versions, and carries no known security vulnerabilities. Installation is straightforward via pip with low friction.","worth_installing":"Yes. openapi-core is well-maintained, has no known vulnerabilities, and offers low install friction. It is the right choice if you need to validate or unmarshal OpenAPI v3.x data in a Python application, especially if you are already using one of its supported frameworks.
