​
Overview

Moralis uses Compute Units (CUs) to track API usage. Rate limits ensure fair usage and system stability across all users.

All plans include archive request support.

​
Understanding Throughput

  • API Throughput - Maximum CUs per second across all your requests
  • Node Throughput - Maximum CUs per second per individual node
  • Nodes - Number of dedicated node endpoints available

​
Avoiding Rate Limits

To stay within limits:
  1. Monitor your CU consumption in the dashboard
  2. Keep total CU/s below your plan’s throughput
  3. Implement exponential backoff for retries
  4. Cache responses when possible
  5. Use batch requests to reduce HTTP overhead (not CU cost)

​
Rate Limit Response

When rate limited, you’ll receive an HTTP 429 response: 
{
  "jsonrpc": "2.0",
  "error": {
    "code": -32005,
    "message": "Rate limit exceeded"
  },
  "id": 1
}
