Integrity API

The Integrity API provides access to PyPI's implementation of PEP 740.

Concepts

The concepts and objects in the Integrity API closely mirror PEP 740:

Attestation objects encapsulate a single "attestation" for a single file, such as a publish attestation or SLSA Provenance.
Provenance objects encapsulate one or more attestations for a given file, bundling them with the identity that produced them.

The Integrity API deals in provenance objects; users should extract and verify individual attestations from a file's provenance, as appropriate.

Routes

Get provenance for file

Route: GET /integrity/<project>/<version>/<filename>/provenance

Get the provenance object for the given <filename>.

This endpoint is currently only available as JSON.

Example JSON request (default if no Accept header is passed):

GET /integrity/sampleproject/4.0.0/sampleproject-4.0.0.tar.gz/provenance HTTP/1.1
Host: pypi.org
Accept: application/vnd.pypi.integrity.v1+json

Example JSON response

This is an example response, demonstrating a provenance object containing one attestation and its Trusted Publishing identity.
