Getting filler text from the REST API

Getting filler text from the REST API

I had the need to generate some random filler text for a bunch of records today, and I wanted to use the Lorem Ipsum latin text. Normally, I use the great website and fill out the form and hit submit. Then, I copy the text provided into my destination.

(This project (reusable .NET class library and sample app) can be found on GitHub at

However, I needed to automate this process, so I did a little poking around. It turns out that the website exposes a json feed that can be altered based on your needs.

Note: Using the Lipsum website in this manner is placing stress on their web server. As such, I highly suggest using the donate link provided within the data set that is returned to provide them with a little money to support your efforts.

I wrote my code in such a way as to limit the call rate to one call per second. It took a lot longer to insert my records than I wanted, but I felt sure I wasn't putting unneeded strain on their servers.

The main endpoint for accessing the default data set is:

This will give you the following results:

    feed: {
        lipsum: "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras tristique massa eu porttitor aliquam. Vivamus sodales sit amet nulla nec volutpat.

        generated: "Generated 5 paragraphs, 454 words, 3017 bytes of Lorem Ipsum",
        donatelink: "",
        creditlink: "",
        creditname: "James Wilson"

I decided to take a look at the source code for the home page and get an idea of the form names that are used to set the options for the feed.

I found the following query string arguments

  • what: valid values = paras, words, bytes, and lists
  • amount: the amount of the chosen type to return (the minimum value is 5 for words)
  • start: yes or no depending on whether or not you want to start with "Lorem Ipsum". If set to no, you'll get a random return value.

So, I wrote my program to loop through the days in the current year and insert a record for each day, adding the random "lipsum" text to the record.

Here's a quick C# program that will use the Newtonsoft.Json library to deserialize the lipsum result into an object that you can use in your code.

This assumes that you're using Visual Studio (community or professional edition).

First, visit the following url:

Now, view the source of the results and copy them to your clipboard. Start a new project in Visual Studio (if you don't already have one open) and then create a new class. Name the file LoremIpsum.cs.

It will generate the following code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace LoremIpsum
    class LoremIpsum

Delete the class LoremIpsum that it generated (but keep the rest of the file).

Click inside the namespace and choose Edit->Paste Special->Paste JSON as Classes from the main menu.

This will insert classes that are compatible with the lipsum data. Rename the Rootobject class to LoremIpsum. Your code should look like the following (LoremIpsum.cs):

namespace LoremIpsum
    public class LoremIpsum
        public Feed feed { get; set; }

    public class Feed
        public string lipsum { get; set; }
        public string generated { get; set; }
        public string donatelink { get; set; }
        public string creditlink { get; set; }
        public string creditname { get; set; }


Now, we will need to fetch the data and deserialize it into an object we can use.

Before we continue, make sure you have a reference to the Newtonsoft.Json library. You can use nuGet to install it easily.

First, we'll define an enum to represent the result types:

public enum LipsumType

Notice that I used the System.ComponentModel.Description attribute on each of the enum values to represent the values that need to get sent to the api. This will come in handy later.

Here is a generic extension method on enums that will return the description (this works on any enum containing values decorated with the System.ComponentModel.DescriptionAttribute class):

public static string GetDescription(this T e) where T : IConvertible
	Array values = System.Enum.GetValues(e.GetType());
	string description = null;

	foreach (int val in values)
		if (val == e.ToInt32(CultureInfo.InvariantCulture))
			var type = e.GetType();
			var memInfo = type.GetMember(Enum.GetName(type, val));
			var attributes = memInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), false);
			description = ((DescriptionAttribute)attributes[0]).Description;

	return description;

Now, let's move on to the actual web call:

public static readonly string LIPSUM_JSON_URL = "{0}&start={1}&what={2}";

public static LoremIpsum GetNewLipsum(LipsumType lipsumType, int amount, bool startWithLoremIpsum = true, ICredentials proxyCredentials = null)
	string requestUrl = string.Format(LIPSUM_JSON_URL, amount, startWithLoremIpsum ? "yes" : "no", lipsumType.GetDescription());

	HttpWebRequest request = WebRequest.Create(requestUrl) as HttpWebRequest;

	if (proxyCredentials != null)
		request.Proxy.Credentials = proxyCredentials;

	using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
		if (response.StatusCode != HttpStatusCode.OK)
			throw new Exception(String.Format(
			"Server error (HTTP {0}: {1}).",

		StreamReader sr = new StreamReader(response.GetResponseStream());
		JsonTextReader tr = new JsonTextReader(sr);
		JsonSerializer ser = new JsonSerializer();

		return ser.Deserialize(tr);

In the requestUrl definition, I used the LipsumType.GetDescription() extension method that I defined earlier to send the correct type based on what was chosen by the caller.

Don't forget to use the using() {} when dealing with an object that implements IDisposable. It will clean up after you and prevent you from leaving any machine resources open.

Notice the use of the ser.Deserialize<LoremIpsum>() call (GitHub source). I was able to do this because we created a class directly from the JSON data. We then use this class with the Json (de)serializer to get an instance of the LoremIpsum class containing the results of our call.

Here is the main() method of the program that ties it all together:

static void Main(string[] args)
	for (int i = 0; i < 10; i++)
		// toggle between words and paragraphs
		bool isEven = (i % 2) == 0;
		bool isThird = (i % 3) == 0;
		LipsumType lipsumType = isEven ? LipsumType.Paragraphs : LipsumType.Words;

		// only start with Lorem Ipsum every third call
		Debug.WriteLine(LoremIpsumUtil.GetNewLipsum(lipsumType, 7, isThird).feed.lipsum + Environment.NewLine);

		// sleep for 1 second to give the server a rest

This simply loops 10 times and makes a call to the json endpoint, toggling between paragraphs and words, as well as starting with "Lorem Ipsum" every third call. It also waits one second between each call to be friendly to the server.

Because we get back a fully populated object, we can also access the other properties on the LoremIpsum instance, like *.feed.generated and *.feed.donatelink.

Update: I've written a post that describes how to get PascalCased property names.
