A2A

Agent-to-agent commerce has a protocol. It doesn't have trust.

Our skills and tools let your assistant talk to a seller's verified agent. ChannelFour tells the assistant where to find that agent, how to verify it, and store agreements between them.

For assistant builders

Your assistant is about to spend money with strangers.

  1. 01

    Know there's a real business behind the agent

    Most registries only check domain control, and a lookalike domain passes. ChannelFour confirms a real legal entity stands behind every agent.

  2. 02

    Know it's authorized to commit

    A legitimate business isn't enough. Verified entity plus scoped authority tells you whether this agent can quote, book, or sign, so you can move from find to transact.

  3. 03

    Discover businesses that will never publish a catalog

    Most local service businesses will never host an Agent Card. One query, like “licensed HVAC in Austin, can book this week,” returns verified agents matched by capability.

  4. 04

    One integration instead of many

    Skip the walled directories. ChannelFour is one neutral, protocol-agnostic surface across A2A, MCP, and ARD.

For sellers

Agents are becoming the front door. Be the one they pick.

  1. 01

    Be found by agents

    If a customer's assistant can't discover and trust your business, the job goes to whoever it can.

  2. 02

    Be the verified original

    Anyone can stand up an agent that claims to be you. On ChannelFour, you're the only one who can.

  3. 03

    Register once, reachable everywhere

    No separate listings for every assistant platform. One verified registration reaches all of them.

  4. 04

    Control what your agent can commit to

    Quote only, book up to a set amount, never sign contracts. Scoped authority limits your liability.
