Rate Limits - Avalanche APIs & SDKs Documentation

Rate limiting is managed through a weighted scoring system, known as Compute Units (CUs). Each API request consumes a specified number of CUs, determined by the complexity of the request. This system is designed to accommodate basic requests while efficiently handling more computationally intensive operations.

Rate Limit Tiers

The maximum CUs (rate-limiting score) for a user depends on their subscription level and is delineated in the following table:

Subscription Level	Per Minute Limit (CUs)	Per Day Limit (CUs)
Unauthenticated	6,000	1,200,000
Free	8,000	2,000,000
Base	10,000	3,750,000
Growth	14,000	11,200,000
Pro	20,000	25,000,000

To update your subscription level use the AvaCloud Portal

Note: Rate limits apply collectively across both Webhooks and Data APIs, with usage from each counting toward your total CU limit.

Rate Limit Categories

The CUs for each category are defined in the following table:

Weight	CU Value
Free	1
Small	10
Medium	20
Large	50
XL	100
XXL	200
