Evmos Quick Facts

Evmos is a scalable and interoperable Ethereum compatible network. It is built on the consensus mechanism of Proof-of-Stake with fast-finality. Evmos is an application-agnostic Cosmos chain that will be interoperable with the Ethereum mainnet, and Ethereum Virtual Machine (EVM) compatible environments, and other Byzantine Fault Tolerance (BFT) chains via Inter-Blockchain Communication (IBC), making it easy for users and developers to interact seamlessly between chains. Evmos aims to be the EVM Hub of Cosmos, making it easy for smart contracts to deploy and communicate within the Cosmos ecosystem.

FAQ

These FAQs are a self-serve support resource for the Covalent API.

Base URL

The API Host for all requests is https://api.covalenthq.com/v1. Some additional points to keep in mind:

  • All requests are done over HTTPS (calls over plain HTTP will fail.)
  • The default return format for all endpoints is JSON unless the query parameter format=csv is specified.
  • All requests require authentication.

Authentication

To access the Covalent API, you will need an API key. Various authentication mechanisms are available:

Authentication via Query parameter

curl -X GET https://api.covalenthq.com/v1/ENDPOINT/?key=API_KEY

Append key=API_KEY as a query parameter to all requests.

Authentication via Basic Auth

 curl -X GET https://api.covalenthq.com/v1/ENDPOINT/ \
                -u API_KEY:
                -H 'Content-Type: application/json'
                # The colon prevents curl from asking for a password.

Provide your API key as the basic auth username. You do not need to provide a password.
