# API > This document is a work in progress. The systems API is defined in here. The **JSON RPC** maps directly to the API defined here using the [JSON RPC package](https://github.com/filecoin-project/lotus/tree/master/lib/jsonrpc). ## Overview By default `127.0.0.1:1234` - **daemon** stores the API endpoint multiaddr in `~/.lotus/api` - `http://[api:port]/rpc/v0` - **JSON RPC** HTTP endpoint - `ws://[api:port]/rpc/v0` - **JSON RPC** websocket endpoint - `PUT http://[api:port]/rest/v0/import` - import file to the node repo, it requires write permission. For **JSON RPC** interface definition see [api/api.go](https://github.com/filecoin-project/lotus/blob/master/api/api_full.go). Required permissions are defined in [api/struct.go](https://github.com/filecoin-project/lotus/blob/master/api/struct.go) ## Auth **JWT** in the `Authorization: Bearer ` http header Permissions - `read` - Read node state, no private data - `write` - Write to local store / chain, read private data - `sign` - Use private keys stored in wallet for signing - `admin` - Manage permissions Payload ```json { "Allow": ["read", "write", ...] } ``` Admin token is stored in `~/.lotus/token`
