API Management

When I was trying to learn more about API as products and product management there, it was very difficult to find any kind of like widely available resources or even books. Working on brand new products has to be honest always been quite accidental. So in a way, I would want to move onto products where they already in kind of like more mature phase beyond product market fit. But at the same time, I'm scared to lose this sense of being uncomfortable all the time because it feels like at that point, you are already at a more stable place with customers.
