Purpose:

Contains functions implementing calls to Covalent API endpoints

Official Covalent API docs

https://www.covalenthq.com/docs/api/

Installation and Useful Notes

1. Create a Covalent API token: https://www.covalenthq.com/platform/#/auth/register (skip this step if you have a token already)
2. Download covalent-api-ps-module.psm1 file
3. Run the command to import the module: Import-Module "<path to the folder where the file was saved>\covalent-api-ps-module.psm1" -Force
4. Set $env:COVALENT_API_TOKEN environment variable: $env:COVALENT_API_TOKEN = "<your token>"
5. Default quote currency is USD. To change that, either set $env:QUOTE_CURRENCY variable or use -QuoteCurrency parameter available in many functions
6. Default output format is JSON. To change that, either set $env:OUTPUT_FORMAT variable or use -Format parameter available in many functions
7. Default Covalent API url is https://api.covalenthq.com/v1, but it can be changed via -APIUrl parameter of each function if needed
8. Many functions have the pagination parameters -PageNumber and -PageSize which can be used to limit output
9. Many functions have ChainId parameter. A list of supported blockchain networks can be found here
10. Covalent offers the query language Primer which makes it easy for users to further process and transform the records in the Covalent API responses for their custom use-cases. All class A functions have the Primer parameters: Primer, Match, Group, Sort, Skip, Limit. It is better to use single quotes when working with the Primer queries to avoid escaping double quotes. Examples: -Match '{"gas_spent": {"$lt": 200000} }'
