Go ahead and test the API from the command line, as we did in [tutorial part 1][tut-1]. Everything is working pretty similarly, although we've got some nicer error handling if we send invalid requests.
**TODO: Describe using accept headers, content-type headers, and format suffixed URLs**
We can get a list of all of the snippets, as before.
curl http://127.0.0.1:8000/snippets/
[{"id": 1, "title": "", "code": "foo = \"bar\"\n", "linenos": false, "language": "python", "style": "friendly"}, {"id": 2, "title": "", "code": "print \"hello, world\"\n", "linenos": false, "language": "python", "style": "friendly"}]
We can control the format of the response that we get back, either by using the `Accept` header:
curl http://127.0.0.1:8000/snippets/ -H 'Accept: application/json' # Request JSON
curl http://127.0.0.1:8000/snippets/ -H 'Accept: text/html' # Request HTML
Or by appending a format suffix:
curl http://127.0.0.1:8000/snippets/.json # JSON suffix
curl http://127.0.0.1:8000/snippets/.api # Browseable API suffix
Similarly, we can control the format of the request that we send, using the `Content-Type` header.
# POST using form data
curl -X POST http://127.0.0.1:8000/snippets/ -d "code=print 123"
{"id": 3, "title": "", "code": "123", "linenos": false, "language": "python", "style": "friendly"}
# POST using JSON
curl -X POST http://127.0.0.1:8000/snippets/ -d '{"code": "print 456"}' -H "Content-Type: application/json"
{"id": 4, "title": "", "code": "print 456", "linenos": true, "language": "python", "style": "friendly"}
Now go and open the API in a web browser, by visiting [http://127.0.0.1:8000/snippets/][devserver].
### Browsability
Because the API chooses a return format based on what the client asks for, it will, by default, return an HTML-formatted representation of the resource when that resource is requested by a browser. This allows for the API to be easily browsable and usable by humans.
Because the API chooses the content type of the response based on the client request, it will, by default, return an HTML-formatted representation of the resource when that resource is requested by a web browser. This allows for the API to return a fully web-browsable HTML representation.
Having a web-browseable API is a huge usability win, and makes developing and using your API much easier. It also dramatically lowers the barrier-to-entry for other developers wanting to inspect and work with your API.
See the [browsable api][browseable-api] topic for more information about the browsable API feature and how to customize it.
