This is why I will never create a business based on an API of a third-party. They can take it away at any time..and your business is done.

[egeozcan]

I think it doesn't make sense at all or is at least very dangerous to build a business having a third party as a single point of failure at any point of its core operations.

To generalize even more, a good long-term plan should be free of any kind of single point of failures.

Even if that company's business is providing the API?

[spacefight]

Of course - they can retire said API and don't extend your contract. Or they can force you to a different API etc etc.
