Common Developer Questions

As developers begin to integrate the Metals-API into their applications, they may encounter several common questions:

How do I authenticate my API requests?

Authentication is achieved by including your unique API key in the access_key parameter of your requests. Ensure that your key is kept secure and not exposed in public repositories.

What are the rate limits for API requests?

Rate limits vary depending on your subscription plan. Be sure to check the documentation for specific limits to avoid exceeding your quota.

How can I handle errors in API responses?

API responses include error codes that can help you diagnose issues. Implement error handling in your application to manage these responses gracefully and provide feedback to users.

Performance Optimization Strategies

When working with the Metals-API, consider the following strategies to optimize performance:

• Caching: Implement caching mechanisms to store frequently accessed data, reducing the number of API calls and improving response times.
• Batch Requests: If your application requires multiple data points, consider batching requests to minimize the number of calls made to the API.
• Asynchronous Processing: Use asynchronous programming techniques to handle API requests without blocking the main application thread, enhancing user experience.

Security Considerations

Security is paramount when dealing with financial data. Here are some best practices to ensure the safety of your application:

• Secure API Key Storage: Store your API key securely, using environment variables or secure vaults to prevent unauthorized access.
• Data Validation: Validate all incoming data to prevent injection attacks and ensure data integrity.
• HTTPS Protocol: Always use HTTPS for API requests to encrypt data in transit and protect against eavesdropping.
