+name: Have I Been Pwned
+version: 1.0.0
+description: "Have I Been Pwned (API v3 + Pwned Passwords) — breach enrichment: check an email for breaches and pastes, list and read breaches, and check whether a password appears in breaches (k-anonymity, password never sent). API-key authentication; stdlib-only, no extra Python dependencies."
+changelog: "1.0.0 — Initial release: account breaches/pastes, list/get breach, password pwned check."
+category: enrichment
+
+# Per-instance configuration. The API key is sent as the 'hibp-api-key' header
+# (required for account lookups). A User-Agent is always sent, as HIBP requires.
