This mirrors the current Cookbook. The assistant first asks to call your function, then you return the result using function_call_result.

​
1) Initial request (expose calculator)

curl -X POST "https://api.incredible.one/v1/chat-completion" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "small-1",
    "stream": false,
    "messages": [{"role": "user", "content": "What is 127 + 349?"}],
    "functions": [{
      "name": "calculate_sum",
      "description": "Add two numbers together and return the sum",
      "parameters": {
        "type": "object",
        "properties": {
          "a": {"type": "number"},
          "b": {"type": "number"}
        },
        "required": ["a", "b"]
      }
    }]
  }'
The response includes a type: "function_call" with function_call_id and arguments.
