id property
ID is the wallet id, minted by the server as "wal_" + 24 hex. It is the last segment of the key ref, and it is the LEDGER SUBJECT an x402 payment into this wallet credits — so it names money as well as key material.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? id;
