Take a look through the GitHub repo https://github.com/mc1903/PS-OpenAI and you will find the url in each of the functions under /Src/Public/
They use the [uri]$url = "https://api.openai.com/*" variable.
Just be aware that some of the totals return a value 100x the actual usage.
For instance my billing for yesterday was 0.05 (5 cents), but the https://api.openai.com/dashboard/billing/usage endpoint returns my total_usage as 4.562
