Requirements
Python 3.10 or newer and local filesystem access. Checkout requires an x402-compatible client and USDC on Base Mainnet.
The checks are structural and do not prove semantic accuracy, compliance or destination-system compatibility. The tool does not fix data automatically and does not modify source files.
Common questions
How is this different from the $9 toolkit?
The core toolkit provides the checker, examples and operating guides. This pack adds the structured audit workflow, three editable evidence templates, provenance and file-level QA manifest.
Does my data leave my machine?
No. The included checker makes no network calls. PayanAgent and x402 are used only for checkout and ZIP delivery.
Does it perform a custom audit for me?
No. This is a reusable local tool pack, not a managed audit, legal opinion, compliance assessment or integration service.
