After understanding how to create API Keys, it`s time to understand how to use them

1. Head to https://thegraph.com/explorer

1. Select the network you want the subgraph of, for example here, we choose Livepeer

https://thegraph.com/explorer/subgraph?id=FDD65maya4xVfPnCjSgDRBz6UBWKAcmGtgY6BmUueJCg&view=Overview

1. Copy the Query URL, in Livepeer`s scenario, the Query URL is

https://gateway.thegraph.com/api/[api-key]/subgraphs/id/FDD65maya4xVfPnCjSgDRBz6UBWKAcmGtgY6BmUueJCg

The above said link mentions [api-key]

This is where you copy and paste your created API Key 4b721*********************7ae8c5 . After generating the new Query URL, it would look something like this

https://gateway.thegraph.com/api/4b721*********************7ae8c5/subgraphs/id/FDD65maya4xVfPnCjSgDRBz6UBWKAcmGtgY6BmUueJCg

1. Copy-paste this URL in our Subgraph API Endpoint input box

1. Click explore and Start exploring and visualizing.
