Compute Units

Understanding Compute Units (CUs)

What are Compute Units

Compute Units (CUs) measure the computational resources consumed by your API calls. They provide a standardized way to quantify usage across different types of requests.

Why use Compute Units?

CUs ensure transparent and fair pricing. Instead of flat rates, you pay based on the actual computational cost of your requests. This approach prevents overpaying for simple queries while accurately reflecting resource usage for complex operations.
