## Response `200`

Successful operation

- UnsignedTx
  - `tx` string, required — Base64Check encoded tagged byte array

## Other responses

- `400` — Invalid transaction
- `404` — Initiator not found
- `503` — The node is temporarily unable to handle the request: either its request queues are saturated (overload protection) or it has not yet reached a stable mode. Overload protection is applied to every endpoint, so this response can be returned by any operation. The Retry-After header tells the client how long to back off before retrying.

## Changes

- **2026-07-27** `ca5dd7bf8408` — 1 info
  - added the non-success response with the status `503`
