Common Developer Questions

How do I authenticate with the Metals-API? You need to include your unique API key in the access_key parameter of the API base URL.
What are the rate limits for API requests? Rate limits depend on your subscription plan, so it's essential to review the plan details to avoid exceeding limits.
How can I handle errors in API responses? Implement error handling to manage different response scenarios, such as invalid parameters or rate limit exceeded errors.

Performance Optimization and Scaling

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 individual API calls.
Asynchronous Processing: Use asynchronous processing to handle API requests, allowing your application to remain responsive while waiting for data.

Security Considerations

API Key Management: Keep your API key secure and do not expose it in client-side code.
Data Validation: Validate all incoming data to prevent injection attacks and ensure data integrity.
Rate Limiting: Monitor your API usage to avoid exceeding rate limits, which can lead to temporary bans.
