What it does

When you give an AI agent your API key, you can't revoke just that agent's access without rotating the key. BlackVault fixes this:

Agent → BlackVault (proxy token) → OpenAI/Anthropic/Google (real key)

Kill the proxy token = instant 401. The agent never sees the real key.

Features

• AES-256-GCM encrypted vault with per-user derived keys
• Proxy gateway with SSE streaming (OpenAI, Anthropic, Google AI)
• Instant kill switch — per-session, per-key, or global
• Per-session cost tracking
• Activity audit trail
• Self-hostable, MIT licensed, free
