Responses

Create a response

curl "$CCSIO_BASE_URL/responses" \
  -H "Authorization: Bearer $CCSIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "your-responses-model",
    "instructions": "Answer in one short sentence.",
    "input": "What is an API gateway?"
  }'

input is a string or a list of input items; instructions is prepended as the system prompt. With "stream": true the answer is a stream of event-named server-sent events.

What is different from OpenAI

• The answer carries text output only: tool calls and reasoning items of the model do not come back. For tools, use Chat completions.
• The platform stores no response: store, previous_response_id and background are passed on but have no effect. Send the context you need in input.
• status is completed, or incomplete with incomplete_details.reason when the model stopped early (for example at max_output_tokens).
