Karma.Domains is an expired and auction domain research tool that checks each domain's Wayback Machine history and shows a Karma Score, with filters and a REST API, CLI, SDKs and MCP server. New users get 5 free credits, with credit packs from $14.99 and an Unlimited plan at $27.99 for 30 days. API and MCP access need the Pro plan at $57.99 per month.

Checking an expired domain properly means opening many Wayback Machine snapshots to see whether it was ever a spam site, then cross-checking SEO metrics in other tools. Karma.Domains does that history check for you.
