No, there is no publicly available API.

Please vote up the appropriate feedback item if you would like one. And while you’re at it, let us know exactly what you’re looking to gain access to, how many requests you want to make per month, even how much you’d be willing to pay.

What about privately available you ask? Well if you’re looking to make > 5000 requests per month, and willing to pay some upfront development costs, we could maybe build something custom for you. Just let us know what you want in as much detail as possible.

We do a lot more one time custom list creation rather than custom APIs. So if that is an option then contact us regarding that.
