# NFT API: Optimized endpoint

\[Oct 08, 2023]

We added the 'unit' parameter to the [\[Get chart of market capitalization by collection\] ](https://docs.nftgo.io/reference/get_marketcap_chart_eth_v1_collection__collection__chart_marketcap_get). Now, you can choose between USD or ETH as the unit when retrieving the market capitalization of collections, with USD being the default option.
