All Moralis plans come with generous monthly request limits. The number of included requests depends on your plan - check the pricing page for details. Moralis uses Compute Units (CUs) as a standard way to measure and bill for usage across all products - including Data API, Streams, Datashare, and RPC Nodes. CUs provide a unified way to account for computational complexity and rate limits, regardless of the product you’re using.

​
What is a Compute Unit?

A Compute Unit (CU) represents the relative computational cost of a request, task, or operation within the Moralis platform. Simple operations consume fewer CUs, while more complex or resource-intensive ones consume more. For example:
  • A basic wallet balance check may consume a small number of CUs.
  • A multi-chain portfolio aggregation, or a high-frequency stream of on-chain events, may consume significantly more.
CUs ensure you’re only billed for the resources you actually use - and that high-load workloads are fairly metered across the system.

​
CU Cost

Each product applies CU-based billing differently. Generally:
  • CUs are deducted from your plan’s included quota.
  • Usage beyond your quota may incur overage charges, depending on your plan and product.
Visit the individual pricing pages to see how CUs apply to each product:

​
CU Throughput (CU/s)

CUs are also used to enforce rate limits, measured in CUs per second (CU/s). This helps manage request throughput and protect system performance - allowing heavier requests to be made less frequently, while lightweight calls remain fast and responsive. Different products may enforce CU/s limits differently. Check the respective documentation for details.
