Playground

Experience the ASP protocol flow in your browser. Walk through a complete transaction — from discovering a restaurant, browsing its menu, placing an order, to tracking delivery — all with real protocol messages.

Step 1: Discover Providers

An agent searches for nearby service providers. Configure the filters below and run the search to see matching results.

Request POST /discovery/search 

    

    

      

        Response
        waiting
      

      
Click "Search Providers" to run the request...

    

  


  

    
    
  







  
Step 2: Browse Catalog

  

    After selecting a provider, the agent fetches their catalog — organized into sections with items and modifier groups for customization.
  


  

    
  


  

    

      

        Request
        GET /catalog/{provider_id}/catalog
      

      

    

    

      

        Response
        waiting
      

      
Click "Fetch Catalog" to load the menu...

    

  


  

    
    
    
  







  
Step 3: Create Checkout

  

    The agent creates a UCP checkout with ASP's fulfillment extension — specifying items with modifiers, delivery details, and optional loyalty info.
  


  

    
    
  


  

    

      

        Request
        POST /checkouts
      

      

    

    

      

        Response
        waiting
      

      
Click "Create Checkout" to place the order...

    

  


  

    
    
    
  







  
Step 4: Track Order

  

    After checkout, the marketplace sends status updates via webhooks. Click through to simulate the order progressing from confirmed to delivered.
  


  

    

      

        Webhook Event
        WEBHOOK order.status_update
      

      

    

    

      

        Order Status
        pending
      

      

    

  


  

    
    
    
  







  
Step 5: Live Streaming (WebSocket)

  

    For truly live updates — GPS location every 3-5 seconds — ASP provides a WebSocket streaming channel. This simulates the full connection lifecycle: subscribe, status snapshot, live location updates during en_route, heartbeats, and graceful close on completion.
  


  

    

      

        WebSocket Messages
        WS wss://host/asp/v1/ws
      

      
Click "Connect & Stream" to open the WebSocket...

    

    

      

        Latest Event
        disconnected
      

      
No events yet...

    

  


  

    
    
    
  







  
Step 6: Submit Review

  

    After delivery, the agent submits a review on behalf of the user — an overall rating, optional comment, and category-specific scores.
  


  

    
  


  

    

      

        Request
        POST /reviews
      

      

    

    

      

        Response
        waiting
      

      
Click "Submit Review" to send the review...

    

  


  

    
    
    
  









How It Works


This playground simulates the six core steps of an ASP transaction:






Step
Capability
What Happens






Discovery
dev.asp.services.discovery
Agent searches for providers by location, category, and rating




Catalog
dev.asp.services.catalog
Agent fetches the provider's menu with items and customization options




Checkout
dev.asp.services.fulfillment
Agent creates a UCP checkout extended with ASP fulfillment details




Tracking
dev.asp.services.order_tracking
Marketplace pushes status updates via webhooks




Live Stream
dev.asp.services.streaming
WebSocket connection streams GPS location updates in real-time




Review
dev.asp.services.reviews
Agent submits a post-service review with rating and category scores






All messages follow the ASP specification schemas. See the Specification Overview for the full protocol details.
