Not observed. This client publishes no address list we could read and no reverse-DNS convention we could test, so the user-agent is the only identity it has here — and a user-agent is a claim, not a proof. Anyone can send this string.
Not observed. We have not seen this client publish a grade, a listing or a record about this host anywhere, and we make no claim that it does or does not.
It names https://api.babyblueviper.com in its own user-agent. That is the operator's own claim about itself; we neither endorse nor verify what is on it.

JSON · markdown · all clients seen here · index as JSON
Rows come from a server-side log written before anything is served, so clients that
run no JavaScript are counted exactly like browsers. The window is the whole life of the log,
2026-09-01 16:15:28Z to 2026-09-01 16:15:28Z UTC, and it is stated on every number because a count without a window is
not a fact. Addresses are stored as salted hashes and counted, never printed. Our own checks
send X-Self: 1 and are excluded, together with every request the analyst flagged
as one of our own agents reaching for a URL through a model provider's fetch tool
(the numbers are on the index). Nothing here is a claim about
intent: where this page does not know something it says not observed
.
