# API keys

<Warning>
  MyAccount API Keys will be deprecated soon in favor of Blockscout PRO API keys. PRO API keys provide universal, multichain access and tiered access included 5 rps for the free plan. Get started at [https://dev.blockscout.com/](https://dev.blockscout.com/)
</Warning>

API Keys are available to enhance request availability. Keys give users the ability to query the API up to 10 requests/sec.

A maximum of 3 keys can be created for each account.

## Create API key

**1) Login to My Account in Blockscout** \<[*login instructions*](/using-blockscout/my-account)> to get started. Once logged in:

1. Go to API keys in the user menu.
2. Press Add API key.

## Use API key

Add the following to the end of a query to use your API key: `&apikey=your-api-key`

For example, a query to get more info on USDT on Optimism with the API key `fdbfa288-1695-454e-a369-4501253a120`would be formatted as follows:

`https://optimism.blockscout.com/api?module=token&action=getToken&contractaddress=0x94b008aA00579c1307B0EF2c499aD98a8ce58e58&apikey=fdbfa288-1695-454e-a369-4501253a120`
