**EDIT**: NASA data can be accessed via the SODA API (see <https://data.nasa.gov/developer>), and the API referred to below seems to be deprecated.

I'm trying to use the NASA API (<http://nasa.github.io/api-docs/#introduction>) to pull information on NASA patents. The docs show what the JSON reponse should look like and list required parameters for the request, but I can't find any examples of a properly formed request URL. So far I have tried (with my API key):

```
https://api.nasa.gov/patents/optics?api_key=API_KEY

https://api.nasa.gov/patents/optics.json?api_key=API_KEY

```

I tested the API key out on an example GET request URL for a different data.gov agency and it returned a valid JSON response, but I've had no luck with the NASA requests.

Does anyone know the proper request format for NASA info from the data.gov API?
