Why is it important to estimate your usage of APIs?

• A. To ensure all code is written correctly
• B. To understand the impact on the overall cost
• C. To check compatibility with different languages
• D. To improve the speed of network communication

Answer: (B)

Estimating your usage of APIs is crucial for understanding the impact on the overall cost. APIs often have associated costs based on usage metrics such as the number of requests made, data returned, or subscriptions utilized. By estimating this usage, organizations can plan their budget and allocate resources more effectively, ensuring they do not exceed their financial limits or exceed allowed quotas. This proactive approach helps in avoiding unexpected charges and allows for better financial forecasting regarding API-related expenses.

Considering the context of the other options, ensuring code correctness is important but doesn't directly relate to API usage estimation. Checking compatibility with different programming languages pertains to software interoperability, which is separate from understanding financial implications. Improving network communication speed involves technical optimizations rather than financial planning, and thus does not relate to the necessity of estimating API usage.
