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.
How this list is made
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
