The Unsafe Consumption of API's

The number 10 is unsafe consumption of API's because, I mean, I've all been talking about for many of the preceding items on the API to tenants that, you know, don't trust user input validate what you can. But what if you are consuming other API's as well? It's like having a dependency in your web application, having other API's. Of course, the data, the information you get from other API's also something that should be validated and cannot automatically be trusted. Because that API might be overtaken by someone else. So you must not trust. Also, do not trust any otherAPI's. You're calling it. Yeah.
