Datacircle lists all the GTM APIs.Every GTM API we find, one row for each plan of each call: what it costs per 1,000, what it charges when it finds nothing, its rate limits, its speed and the fields it returns.Buyers compare plans on the sheet. Each API plan on the sheet links to its own page, with an llms.txt for AI agents. Each plan's page links to the provider's site and API docs.Anyone can download the sheet as CSV, JSON or a zip, with no sign-up. The CSV lists the pages we read each row from.
