Commerce Registry Protocol

The Commerce Registry Protocol is an open, versioned specification for registering commerce gateways, proving domain control, and exposing agent-facing discovery APIs. Any compliant implementation can interoperate — including the public registry at https://registry.betterdata.co and self-hosted deployments.

In this documentation

• Registration API — POST /api/gateways and related registration flows
• Resolution — how agents and resolvers look up gateways
• .well-known specification — discovery file format and trust semantics
