Ask Aletheia a question (streams as Server-Sent Events)

POST

/api/v1/ai/conversations/{id}/messages

curl --request POST \
  --url https://api.aletheia-ops.com/api/v1/ai/conversations/example/messages \
  --header 'Authorization: Bearer <token>' \
  --header 'Content-Type: application/json' \
  --data '{ "content": "example" }'

• Production
• Local development

Streams the answer as Server-Sent Events rather than returning JSON. The response is text/event-stream, with a heartbeat comment roughly every fifteen seconds so intermediaries do not close an idle connection.

Only one turn may be in flight per conversation; a second concurrent request on the same conversation returns 409 turn_in_progress.

Treat unknown event names as ignorable, and do not treat stream end as success — only a completion event means the answer finished. OpenAPI cannot usefully describe an event stream, so the full protocol is documented at https://docs.aletheia-ops.com/api/streaming/
