Liveness/latency pre-flight for a URL: is it up, HTTP status and class, response latency in ms, whether it redirects (and where), content-type and server.
Zero-shot text classification into caller-supplied labels; the result
Zero-shot text classification into caller-supplied labels; the result is validated back into your label set so agents can route on it deterministically.
