Frequently asked questions.

How do API credits work?
Basic requests use 5 credits. Requests with jsRender enabled use 25 credits. Requests with useProxies enabled use 35 credits. Requests with useProxies and jsRender enabled use 60 credits. If you think this credit scheme is dumb email me at jake@diffup.com.
What is a monitored URL?
Diff monitors URLs you set up at a predetermined interval and compares changes to previous requests, watching for dramatic changes in html. These changes are presented to you in an HMTL diff. If the html changes more than a threshold you set, we send you a helpful notification.
How long do you keep monitored URL data for?
Currently we have 3 days of data retention. If this is a dealbreaker for your use case I'd love to know. Send me a message at jake@diffup.com.
Does this work on Amazon, Twitter or Instagram?
Long story short, maybe? As I'm sure you know, scraping isn't a perfect or exact science. Our service partners may limit or restrict scraping certain sites for their own (and your) protection. As we grow here at Diff I'll continuously look for ways to get you the data you need. You're more than welcome to give it a shot-- remember we have a 60-day money back guarantee!
