@steep-rain-99291 The Infracost Run Tasks integration works with Terraform Enterprise but that uses our APIs and our hosted Cloud Pricing API.
You can self-host the Cloud Pricing API but that won’t work with Run Tasks.
Usually I suggest source control integrations due to ease of use and speed, e.g.
GitHub App or
GitLab App (both work with self-hosted Github/Gitlab).
If you can’t use the GitHub/GitLab Apps, I’d suggest
https://www.infracost.io/docs/integrations/cicd/#cicd-integrations with your self-hosted Cloud Pricing API so you can post the pull request comments (the run task integration doesn’t have the notion of PR comments).
