# Welcome ### Overview Our new Carbon Market Cap is a global first: a real-time view of Ethereum-powered carbon usage, this is our initial focus due to the historical usage of **Proof of Work.** The beating heart of our [Carbon Calculator](https://calculator.dovu.earth/) and [Carbon Market Cap](https://carbon.dovu.market/) is our Carbon API. For those not in the know, APIs are used by developers and product teams to augment their offerings and services with new and wonderful features. Help your community understand the impact of their carbon debt on Ethereum and let them know how many DOV tokens they should purchase to offset their debt. Partner with [Dovu](https://www.dovu.earth/) to prove to your community that you are committed to helping the environment moving forward. #### About the Carbon Price API The Dovu Carbon API is organized around [REST](http://en.wikipedia.org/wiki/Representational_State_Transfer) Our API has predictable resource-oriented URLs, returns [JSON-encoded](http://www.json.org/) responses, and uses standard HTTP response codes, authentication, and verbs. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
