Example

curl -X GET https://api.nairi.ai/api/public/v1/messages/MESSAGE_ID \

    headers: {
      Authorization: `Bearer ${process.env.NAIRI_API_KEY}`,
    },

const message = (await res.json()) as {
  id: string;
  status: string;
  content: string;

Queued or pending. The agent is still processing:

Completed. The agent returned a response:

  "updated_at": "2026-04-12T18:47:03.000Z"
}

The cost_usd, *_tokens, and model fields are present on assistant messages when the agent reports usage data (Claude Code and OpenCode harnesses do; Cursor does not). See Cost and token usage for field semantics.

Failed. The message could not be processed:

{
  "id": "cmsg_01KRK1V475HBTME8QJQMAPWK16",
  "job_id": "job_01KRK1V46BXS73CSNK2VR35NPJ",
  "content": "Your task description",
  "role": "user",
  "status": "failed",
  "created_at": "2026-04-12T18:45:12.000Z",
  "updated_at": "2026-04-12T18:45:30.000Z"
}

When a message fails, look for a sibling role: "system" message on the same job_id for details. See List messages.
