Free Tier

The Covalent Unified API has been and always will be free.

All accounts on the Covalent API Free tier will be allocated 100,000 free credits per month. Credits on the free tier are spent across all endpoints and networks (including testnets). Once this free allocation is consumed, calls to the API from that account will be paused.

The Free tier is meant for trying the Covalent API, especially for early-stage projects and hackathon builders.

Key Features

  • 4 RPS

  • 100,000 credits per month, spent across all endpoints and networks (including testnets)

Premium Tier

The Premium tier is available for users who want to scale with us and require better performance and more API call volume for their applications. Access all of our endpoints with better reliability and faster response times.

Key Features

  • 50 RPS

  • 100,000 credits per month, spent across all endpoints and networks (including testnets)

  • Auto-scaling Flex Credits allow your app to consume credits past the included 100,000 credits

  • 10x faster average response time

  • 50% decrease in response time variance

Flex Credits

Covalent uses a credit system to calculate billing for customers in the Premium tier. With a Premium tier account ($50/mo without auto-scale), users are entitled to 100,000 credits to consume with no additional charges. For users that need more credits, they can enable auto-scale.


Setting auto-scale to On enables the use of Flex Credits on your upgraded keys. These credits go into effect once you surpass the 100,000 credits included in the Premium tier. All Flex Credits are charged at $0.001 per credit. You can set a cap for the amount of Flex Credits you would like to enable per billing period (monthly). You will only be charged for what you use, and you won't be able to be charged beyond your cap.

No Auto-scale

Setting auto-scale to Off means you can't consume any credits beyond the 100,000 included in the Premium tier. You can switch auto-scale to On and consume Flex Credits at $0.001 per credit for more credits. To configure auto-scale: log in to your account and go to the Account Billing page.

Credit Pricing Example

Wallet example

Consider a wallet application that supports three blockchains:

  1. Ethereum (7,000 daily active users)

  2. Polygon (3,000 daily active users)

  3. Optimism (1,000 daily active users)

The application uses the balances_v2 endpoint to serve data to its users, and each call to the balances endpoint consumes 1 credit.

The total credit consumption per day is:

+ 3,000
+ 1,000 
= 11,000 credits /day.

In one month, the total credit consumption for the application is:

x 30 days 
= 330,000 credits /month.

The Premium Plan includes 100,000 credits, so the total flex consumption is:

- 100,000
= 230,000 flex credits
= $230 @ $0.001 /credit.

The total cost for the application to run each month is $230 for the credit usage plus $50 for the Premium Plan:

+ $50
= $280 /month.

Transaction example

Consider an app that requests transactions at the latest block height on the Ethereum blockchain, for 1000 daily active users (dau). The application uses the transactions_v3 endpoint, which consumes 0.05 credits per returned transaction item. The default page size is 10 transaction items, which makes the credit cost 0.5 credits per API call. In one month, the total credit consumption is:

  1,000 dau
x 0.05 credits /transaction item
x 10 returned items
x 30 days
= 15,000 credits /month.

Now consider a scenario where the API call should also include all decoded event logs for every transaction. The credit cost to include logs is an additional 0.05 per transaction item, regardless of the number of logs returned per transaction item. This is on top of the 0.05 base credit cost for the returned transaction items, for a total of 0.1 credits per transaction item. In one month, the total credit consumption is:

  1,000 dau
x (0.05 + 0.05) credits /transaction item
x 10 returned items
x 30 days
= 30,000 credits /month.
