Compose uses Server-Sent Events for streaming. Native routes can include Compose events alongside OpenAI-shaped chunks. External routes remove Compose events so OpenAI-compatible clients only see the stream shape they expect.
Chat streaming
curl -N https://api.compose.market/v1/chat/completions \
-H "Authorization: Bearer $COMPOSE_MARKET_API_KEY" \

"stream": true,
"stream_options": { "include_usage": true },
"messages": [
{ "role": "user", "content": "Give me one line." }
]
}'
data: {"id":"resp_...","object":"chat.completion.chunk","choices":[{"delta":{"role":"assistant","content":"Hello"}}]}
data: {"id":"resp_...","object":"chat.completion.chunk","choices":[{"delta":{},"finish_reason":"stop"}]}
data: [DONE]
[DONE].
Responses streaming
POST /v1/responses streams Responses-style events. Use it when you want response IDs, input item retrieval, or previous_response_id history.
