Crypto ETF Sentinel — Launch-timing tracker for launch_imminent US spot crypto ETF issuers: days waiting since 8-A12B plus percentile vs the historical 8-A12B → CERT/EFFECT distribution; the baseline is returned in meta on every call. Use when watching for imminent crypto ETF listings or gauging how overdue one is. Indicative timing, not a predicted launch date.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
