# API keys

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

{% hint style="info" %}
The value of requests per API key is managed via `API_RATE_LIMIT_BY_KEY`. The default value is *50*.
{% endhint %}

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

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

## 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 Quai with the API key `fdbfa288-1695-454e-a369-4501253a120`would be formatted as follows:

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