BitBooth Regex Test: pay 0.001 USDC, safely compile and run a regex against a corpus. Returns structured matches with capture groups, indices, and lengths. JS engine flags (g, i, m, s, u, y, d). Hard CPU deadline guards against catastrophic backtracking (ReDoS) — `regex_timeout` is reported instead of stalling. Stateless, no API key.
Verdict: not verified by an unpaid GET. 401/403/429: auth or bot protection. This says nothing about whether the route works when called as declared.
