Explain what an API is to someone who has never written code. Do not use a restaurant or waiter analogy. Plain prose only — no headings, bullet points, or markdown formatting. Maximum 50 words.

An API is a digital messenger that allows different software programs to communicate. It provides a standard set of rules so one application can request information or services from another. This allows separate systems to work together seamlessly without needing to understand how each other works.

A two-person startup is deciding whether to build their own user authentication or use a hosted provider. Give them a clear recommendation, then the single strongest argument against your own recommendation. Plain prose only — no headings, bullet points, or markdown formatting. Maximum 150 words.

You should use a hosted authentication provider. As a two-person startup, your most valuable asset is time, and building a secure authentication system is a massive engineering distraction. Managed services handle complex security requirements like multi-factor authentication, password hashing, and session management, allowing you to focus entirely on your core product. Outsourcing this reduces your immediate security risk and accelerates your time to market. However, the strongest argument against this choice is the potential for extreme vendor lock-in and escalating costs. As your user base grows, the fees charged by these providers can scale much faster than your revenue, and deeply integrating their proprietary workflows makes it technically difficult and expensive to migrate to a custom solution later.
