What the publisher says

From the PEAC Protocol: Signed interaction receipts repository's README, as published. We do not edit it. Read it on GitHub

PEAC Protocol

Portable signed records for agent, API, MCP, and cross-runtime interactions.

Automated systems call APIs, run tools, make gateway decisions, initiate commerce flows, and provision resources across organizational boundaries.

PEAC lets those systems issue portable signed interaction records so another party can verify what the issuer reported, locally, offline, or across system boundaries, without relying only on screenshots or private logs.

Record locally. Verify across boundaries.

PEAC Protocol is open-source software published and maintained by Originary, with contributions from the community.

This repository contains the official source code, releases, and developer tooling distributed under the Apache-2.0 license.

Verify a record offline

Generate the shipped sample records, then verify one locally with the generated issuer key set. The verification step does not fetch keys or call a remote verifier. pnpm dlx may download the CLI if it is not already cached.

pnpm dlx @peac/cli samples generate -o ./s
pnpm dlx @peac/cli verify ./s/valid/basic-record.jws --public-key ./s/bundles/sandbox-jwks.json

Expected:

Signature valid (offline).

What PEAC records

A PEAC record is a signed statement about an interaction or challenge: what the issuing system reported, not an independently established fact.

Shortened. The full README is on GitHub.
