One of the most requested feature for PageGlimpse was a way to check whether PageGlimpse already has a thumbnail for a specific URL. This feature is mostly used in applications that want to poll until a thumbnail exists, before displaying it.
The feature was released today. Like all PageGlimpse APIs, this new feature is straight forward:
The server will return a JSON string (which you can use in your javascript code) indicating whether the request was successful or not (the thumbnail exists or not)
| 200 | ["result", "yes"] |
PageGlimpse has a thumbnail for the requested url. |
| 404 | ["result", "no"] |
PageGlimpse does not have a thumbnail for the requested url. |

If a thumbnail doesn’t exist yet, does a call to “exist” add the creation process of the thumbnail to the queue, so that I can poll again in 10-60 seconds?
