API keys

Last updated 1 year ago

Was this helpful?

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

The value of requests per API key is managed via API_RATE_LIMIT_BY_KEY. The default value is 50.

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

Create API key

1) Login to My Account in Blockscout <> to get started. Once logged in:

  1. Go to API keys in the user menu.

  2. Press Add API key.

2) Fill in the Name field. Add a Name for your API key. This is for your information only and to differentiate between different keys. Press Generate API key.

3) API key generated. The API Key is now added to your API dashboard. You can copy the key or edit the name/delete the key at any time. In addition you can add 2 additional keys (up to 3 per account).

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-a369-4501253a120would be formatted as follows:

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