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.
