Stack AI currently holds a silver deskmark here — Rank 3 of 8 · AI Agent Platforms. Anyone may show it. There is nothing to apply for, nothing to pay, and displaying it changes no score: the standing comes from the published algorithm and money never touches it.
The image is drawn from our live data, so it follows the standing rather than freezing it: if Stack AI moves up or down a tier, the plaque on your own site says so at our next publish. Nothing is tracked beyond the ordinary web-server log that records any image request.
