   This issue might be a duplicate of existing issues. Please check:

   • [question] API documentation #2168: Similar question about API documentation and expected flow for session endpoints, specifically asking about how to determine when AI response has ended and proper polling patterns

   Feel free to ignore if none of these address your specific case.

   @dayeguilaiye are you able to get the messageID of the response?

   Also I feel like if you do get a response after sending the prompt, that is your indication that the operation is completed. Not sure you will get a response without OpenCode being done.

   @dayeguilaiye if u send a request to /session/${sessionId}/message the request is finished after llm finishes... isn't that the best indicator here?

   EX:

   #!/bin/bash
   
   BASE_URL="http://127.0.0.1:55028"
   
   echo "Creating session..."
   SESSION_RESPONSE=$(curl -s -X POST "$BASE_URL/session" \
     -H "Content-Type: application/json" \
     -d '{"title": "Test Session"}')
   
   SESSION_ID=$(echo "$SESSION_RESPONSE" | jq -r '.id')
   echo "Created session: $SESSION_ID"
   
   echo -e "\nSending prompt..."
   PROMPT_RESPONSE=$(curl -s -X POST "$BASE_URL/session/$SESSION_ID/message" \
     -H "Content-Type: application/json" \
     -d '{
       "parts": [
         {
           "type": "text",
           "text": "Hello! Can you help me understand how this works?"
         }
       ],
       "model": {
         "providerID": "openai",
         "modelID": "gpt-4"
       }
     }')
   
   echo -e "\nResponse:"
   echo "$PROMPT_RESPONSE" | jq '.'
   
   echo -e "\nGetting all messages..."
   MESSAGES_RESPONSE=$(curl -s -X GET "$BASE_URL/session/$SESSION_ID/message")
   echo "$MESSAGES_RESPONSE" | jq '.'

   @OpeOginni @rekram1-node Thank you very much for your reply. I didn't realize that POST /session/{id}/message is a synchronous interface; I thought it was asynchronous. So as long as this interface doesn't return, it means the agent is still running.
