Case 3 — Backlinko leaked key
Hackbot suggests closing as a duplicate of informative #2877712 (archived key). Verify it yourself.
Step 1 — unauthenticated leak:
GET /backlinko/wp-json/acf/themeOptionsGeneral
Step 2 — test the key live:
GET /api/v4/projects
X-Api-Key: <semrushApiKey from step 1>
Triage questions: is the key working right now or dead/archived? Is the balance live (moving)? What is the scope — one Backlinko account or the whole platform? Is this really the Wayback-informative class?
