# versyn

**Cryptographic proof for AI actions.** Sign any AI decision with Ed25519, verify it offline against a pinned public key.

## Install

    pip install versyn

## Use

    import versyn
    key  = versyn.register("you@company.com")
    cert = versyn.certify(
        {"kind": "agent.decision",
         "payload": {"agent": "underwriter", "action": "decline"}},
        api_key=key,
    )
    print(versyn.verify(cert))   # True - checked locally, no network call

`versyn.verify()` runs on your machine. It checks the Ed25519 signature against a pinned public key - it does not call Versyn. If our servers vanished, your certificates stay verifiable.

## What this is

A Versyn certificate proves a record was signed at a specific time and has not been altered since. It does not prove the decision was correct, and is not by itself regulatory compliance. It is the verifiable evidence layer beneath your governance.
