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:

​
Dynamic Endpoints

Some API endpoints have dynamic CU costs that scale based on the scope of the request. Instead of a fixed cost per call, these endpoints charge a base CU amount multiplied by a variable factor such as the number of chains, wallets, or addresses involved. For example:
  • An endpoint costing 50 CUs per chain that queries 3 chains will consume 150 CUs total.
  • An endpoint costing 250 CUs per chain that queries 5 chains will consume 1,250 CUs total.
Dynamic endpoints are clearly marked on their respective documentation pages. You can find CU costs for all endpoints on the individual product pricing pages listed above.

​
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.
