Create responses with support for streaming, reasoning, prior response state, and optional Remote MCP tools.

cURL (non‑streaming)

curl http://localhost:1234/v1/responses \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/gpt-oss-20b",
    "input": "Provide a prime number less than 50",
    "reasoning": { "effort": "low" }
  }'

Stateful follow‑up

Use the id from a previous response as previous_response_id.

curl http://localhost:1234/v1/responses \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/gpt-oss-20b",
    "input": "Multiply it by 2",
    "previous_response_id": "resp_123"
  }'

Streaming

curl http://localhost:1234/v1/responses \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/gpt-oss-20b",
    "input": "Hello",
    "stream": true
  }'

You will receive SSE events such as response.created, response.output_text.delta, and response.completed.

Tools and Remote MCP (opt‑in)

Enable Remote MCP in the app (Developer → Settings). Example payload using an MCP server tool:

curl http://localhost:1234/v1/responses \
  -H "Content-Type: application/json" \
  -d '{
    "model": "ibm/granite-4-micro",
    "input": "What is the top trending model on hugging face?",
    "tools": [
      {
        "type": "mcp",
        "server_label": "huggingface",
        "server_url": "https://huggingface.co/mcp",
        "allowed_tools": [
          "model_search"
        ]
      }
    ]
  }'
