### Description (declared)

Find the best GTM APIs. We benchmark all the GTM APIs and we put the results on our website. Our MCP server is open the same way: add api.datacircle.dev/mcp to Claude, ChatGPT or Cursor. It answers from the sheet. list_apis lists the APIs on the sheet. search_plans finds plans by API, provider or price. Each plan comes with its score, and the best come first, as on the sheet.
