### Bugs
- The code does not contain any explicit functional bugs, but exposing an API key in plain text is a security risk.

### Optimizations
- Instead of hardcoding the API key in the source code, consider fetching it from a secured environment variable or configuration file.
- Use encryption to further secure sensitive data.

### Good points
- The code is simple and easily readable.
- It uses a constant modifier which prevents accidental modification of the API key.

### Summary
This code snippet exposes a sensitive API key as a plaintext string, which poses significant security risks depending on its usage. It is essential to manage secrets properly and instead use secure methods for handling API keys and other sensitive information.

### Open source alternatives
- [dotenv](https://github.com/motdotla/dotenv) for environment variable management in Node.js.
- [ConfigParser](https://github.com/lorenzwalthert/config) used in Python for managing configuration files.
- [AWS Secrets Manager](https://aws.amazon.com/secrets-manager/) for secure storage and access of secrets in AWS environments.
