# HTTP API Quickstart

## Get all the Deivice EUIs

In this quickstart, we will use `curl` to issue HTTP requests. The example below calls an API to retrieve all the device EUIs belonging to you.

```bash
curl --user "<access_id>:<access_key>" \
     https://sensecap-openapi.seeed.cc/1.0/lists/devices/eui
```

You should replace `<access_id>` and `<access_key>` with the one you got before. The command will output like the following

```javascript
{
  "code": "0",
  "data": {
    "gateway": [
      "2CF7F1121130003F",
      "2CF7F1100470001A"
    ],
    "node": [
      "2CF7F12210400031",
      "2CF7F12210400005",
      "2CF7F12210400023"
    ]
  },
  "time": 0.314
}
```
