sigil_listUsernames
List all usernames owned by a DID.
Method
sigil_listUsernames is registered in the canonical JSON-RPC catalog. Use POST /rpc, Content-Type: application/json, JSON-RPC 2.0 and a caller-controlled request id. Node RPC profile, build feature and runtime activation checks still apply.
List all usernames owned by a DID.
Request binding
Source handler: rpc_username::handle_list_usernames in sigil/node/sigil-node/src/rpc_username.rs, line 83.
The handler uses no directly named params.get fields, or delegates input parsing to a typed helper. Use the request types below rather than assuming an empty parameter object.
Parsing excerpt
These source excerpts show binding and validation; they are not runnable client code.
let owner = match extract_string_param(&req.params, 0, "owner_did") {
Some(d) => d,
None => return RpcResponse::error(req.id.clone(), -32602, "missing 'owner_did' parameter"),
};Responses and failures
Check HTTP status, parse the JSON-RPC envelope, reject error, and require result on success. Preserve large base-unit integers without floating-point rounding. A catalog method does not bypass authentication, capability, policy or activation requirements.
