--- title: "Platform APIs" --- Call platform adapter APIs using a bot UUID. Continue using `self.plugin.send_message()` for message chains; use the API below for groups, users, and other platform features. ## Call a platform API ```python async def call_platform_api( self, bot_uuid: str, action: str, params: dict[str, Any] | None = None, ) -> Any: ... ``` Call through `self.plugin` in Command, EventListener, Tool, and other regular components. Results are serialized dictionaries, lists, scalars, or `None`, depending on the action, rather than platform SDK objects. ```python group = await self.plugin.call_platform_api( bot_uuid=bot_uuid, action="get_group_info", params={"group_id": "123456"}, ) ``` `bot_uuid` comes from `await self.plugin.get_bots()` or `await event_context.get_bot_uuid()` in a Pipeline event. Use platform IDs from real events or platform configuration. ### Common actions | `action` | `params` | | --- | --- | | `get_user_info` | `user_id` | | `get_friend_list` | `{}` | | `get_group_info` | `group_id` | | `get_group_list` | `{}` | | `get_group_member_list` | `group_id` | | `get_group_member_info` | `group_id`, `user_id` | | `get_message` / `delete_message` | `chat_type`, `chat_id`, `message_id` | | `set_group_name` | `group_id`, `name` | | `mute_member` | `group_id`, `user_id`, `duration` | | `unmute_member` / `kick_member` | `group_id`, `user_id` | | `leave_group` | `group_id` | | `approve_friend_request` | `request_id`, `approve`, `remark` | | `approve_group_invite` | `request_id`, `approve` | | `get_file_url` | `file_id` | Supported actions vary by platform and may require bot administrator permissions. `duration` is in seconds; the meaning of `0` is platform-specific, not a universal permanent mute. Queries may depend on platform caches. Calls raise an exception if the bot is not running, the action is unsupported, or parameters are invalid. ## Platform-specific APIs Set the outer `action` to `call_platform_api` and put the platform action and parameters inside `params`. For example, read the bot account using OneBot Omni: ```python account = await self.plugin.call_platform_api( bot_uuid=bot_uuid, action="call_platform_api", params={"action": "get_login_info", "params": {}}, ) ``` Only actions declared by the adapter are allowed; this is not unrestricted pass-through to every platform endpoint. Plugins call the Host through the runtime, rather than accessing `ctx.query.adapter` or `adapter.bot`. ## Runner During Runner execution, model, tool, knowledge-base, storage, and platform calls through `self.plugin` automatically use the current run and its authorization. Do not pass `run_id`. Concurrent runs remain isolated. Do not continue these run-bound calls after the handler returns. Use `await ctx.get_bot_uuid()` for the current bot. Platform calls must match the tool grants for this invocation. Event-target grants cannot access another target. Ungranted actions, including platform-specific actions, are rejected. These calls also use Mock delivery in debug mode. ```python tools = await ctx.get_available_tools() if any(tool["name"] == "event_get_actor" for tool in tools): actor = await ctx.call_tool("event_get_actor") await ctx.log(str(actor)) ```
