“Find the best GTM APIs. We benchmark all the GTM APIs and we put the results on our website. We list every GTM API we find. Each row is one plan of one API. A row shows the plan's price per 1,000 results and the price of a call with no results. The row has the plan's rate limits, speed and the fields the plan returns too. Call list_apis for the APIs on the sheet, then search_plans for their plans, by API, provider or price. Each plan comes with its score, and the best come first, as on the sheet. Each plan links its page on datacircle.dev (page), and each API its best page (bestPage), which ranks its providers on our benchmark, and its sheet (sheetPage). What each key means: https://datacircle.dev/fields

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks β€” the operator of idle.datacircle.dev controls every word below.

This card declares no skills. That is not a fault β€” the field is optional, and an agent can be perfectly functional without describing itself.

What kind of listing

Checked by agenttru.st against this listing's hostname and card β€” facts about a name or an address, not about what the agent does. How kinds are decided.

What its catalog declares

From the ARD catalog this host publishes at /.well-known/ai-catalog.json. The operator controls every entry; agenttru.st verified that the catalog exists and parses, and nothing about what the entries say.

mcp-server-card

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.
