From each tool's own website. “Not confirmed” means we couldn't confirm it there, not that the tool doesn't have it. Each tool's page says when its facts were checked.

A tool is listed here only when we've confirmed on its own website that it has a public API. Tools we couldn't confirm it for are left out, even if they may have it. Vendors can't pay for a place on this list. Add a tool we missed
