This tests which Hummingbot exchange connectors actually work from your location by fetching trading rules from each one. If you get data back, the exchange is accessible. You can test all connectors at once or filter by spot versus perpetual markets, then search for any token to see a comparison table of minimum order sizes, tick sizes, and order types across every exchange that supports it. The output gets saved to JSON so you're not repeatedly hammering APIs. Honestly most useful when you're figuring out where you can actually trade a specific token or need to know the exact trading rules before placing orders programmatically.
