ACT Protocol is a specification repository for agentic commerce, organized around delegated authorization, commerce interaction, payment services, and trust services. Its main user-facing scenario is an agent discovering and purchasing a paid digital resource: authorization and payment are established, the seller verifies payment evidence, and only then delivers the resource. The repository also provides machine-readable schemas, a local A402 security example, a TSD-CRD credit-association reference flow, a browser showcase, and Alipay integration guidance and code. Runtime wiring beyond the sampled files is not inferred.
