Threadlets capture-only API. Read /openapi.json. Use the Muse bearer credential, never the device pairing code. Submit new notes or unscheduled tasks with a fresh UUID request_id per intended capture; reuse the same UUID and identical inputs on retries. GET /v1/captures/{request_id} checks delivery only. queued means waiting for the iPhone; imported means acknowledged by the device. Never claim queued captures are already on the phone. No access to existing notes or tasks. Undelivered payloads expire 14 days after acceptance. Do not resend expired captures without a new user request.
