NOT AVAILABLE: Bumble retired the API these routes speak. Its endpoint answers every call, the anonymous handshake included, with 'Session not found (0030-3001-0051)', and the Bumble app does not use that endpoint at all: it speaks a binary protocol over a TLS socket to bma.bumble.com:443. No credentials get through until that transport is built, so these calls answer 502 instead of pretending to sign in. Search Bumble for other members, with the app's own filters (gender, age range, radius). Needs a session: this platform has no public listing to read.
