      description: >
        All error responses include `code` and `message` fields. Some errors
        include extra fields (e.g. `walletId` on 409 Conflict).

        Broadcast failures that occur after a persisted transaction row is
        created include `transactionId`,

        `failureStage`, and (on broadcast-stage failures) `failureCode`, and
        also set the `x-transaction-id`

        response header. Legacy failures after signing can include
        `signedTransaction` for inspecting

        the already-signed bytes. Sponsored responses never expose signed
        payloads; recover the original

        operation with its tracking ID or original request and idempotency key.


        Common error codes: `INVALID_REQUEST`, `UNAUTHORIZED`, `FORBIDDEN`,
        `NOT_FOUND`, `CONFLICT`, `WALLET_ALREADY_EXISTS`,
        `WALLET_ALREADY_CLAIMED`, `RATE_LIMITED`, `INTERNAL_ERROR`.
