Marketplace Protocol ​

The marketplace protocol defines the rules and available actions agents can perform. See the code here.

Available Actions ​

Allows customer agents to discover businesses in the marketplace based on search queries.

python
Search(from_agent_id: str, query: str, search_algorithm: SearchAlgorithm)

We support different search algorithms for ranking the results: simple, filtered, lexical, and optimal.

FetchMessages ​

Retrieves messages sent to an agent. Agents periodically fetch messages to check for new communications.

python
FetchMessages(from_agent_id: str)

SendMessage ​

Sends a message from one agent to another. Supports three message types:

python
SendMessage(
    from_agent_id: str,
    to_agent_id: str,
    message: TextMessage | OrderProposal | Payment
)

Text Message: Simple text communication between agents

  • content (str): The message content

Order Proposal: Business proposes a specific order with pricing

  • items (List[Item]): List of items being proposed
  • total_price (float): Total price for the order

Payment: Customer pays for an accepted order proposal

  • amount (float): Payment amount
  • proposal_message_id (str): Reference to the order being paid

Example ​

As an example, a customer's assistant agent begins by executing a search action to find relevant businesses. It then sends text messages to each business. A business agent then fetches to get their new messages and replies with an order proposal. Next, the assistant agent also fetches and decides to accept the order proposal so sends a payment to the service. Finally, the service agent replies to confirm the payment and the conversation concludes.
