# Provides instance identifiers and names for one or more time series identifiers

`GET /series/instances`

The JSON response contains the same information as the **pmseries - i /-- instance** option.
```bash
$ curl -s http://localhost:44322/series/instances?series=605fc77742cd0317597291329561ac4e50c0dd12 | pmjson
```
Alternatively, with no *series* argument, this request will return the list of all known instance names.
```bash
$ curl -s http://localhost:44322/series/instances | pmjson
```
