### Available end points:

- `/instruments/` - Will list all Instruments in the database
- `/instruments.json` - Will return all Instruments in json format
- `/instruments/<object_id>/` - Returns Instruments object with that id

### Available Methods:

- `GET`
- `HEAD`

### Available filters:

- `title`
- `uuid`
- `keywords`

    "title": "PROBA Compact High Resolution Imaging Spectrometer (CHRIS)",
    "abstract": "Proba's main payload is a hyperspectral instrument weighing just 14 kg called CHRIS standing for Compact High Resolution Imaging Spectrometer. Despite this small size and a power requirement of just nine watts CHRIS can image an 18.6 square km area at multiple angles, achieving a resolution of 18 m in up to 19 programmable spectral bands. Furthermore its agile platform can be tilted during acquisition to provide images of the same site taken at different angles. \n\nThat means CHRIS returns a wealth of biophysical and biochemical data as well as visual information about a given target, and can be used for activities including environmental monitoring, crop forecasting, forest cataloguing and marine science.",
