Submit an extension request for existing delegated resources on TronSave via authenticated REST `POST /v2/extend-request`. Requires a logged-in MCP session created by the `tronsave_login` tool: include `mcp-session-id: <sessionId>` returned by `tronsave_login` on subsequent MCP requests. Internal tools never accept API keys via tool arguments; the server forwards the API key cached in session to TronSave internal REST endpoints. Side effect: creates an extension order and may commit TRX from the internal account. `extendData` must follow the REST contract (see schema on each row). Populate it from TronSave outside this MCP—for example the authenticated `POST /v2/get-extendable-delegates` response field `extendData`, or another TronSave client. Do not copy rows blindly from `tronsave_list_extendable_delegates` (GraphQL); that payload shape differs and is for market discovery only.
