  description: |
    **AgentGuard** is the runtime security layer for AI agents. It evaluates live agent actions
    before execution, enforces custom policy, records audit trails, routes sensitive actions
    through approvals, and scans skills, tools, plugins, and MCP servers for supply-chain risk.

    ## Authentication

    AgentGuard supports two authentication methods:

    ### 1. API Key (Subscription)
    Include your API key in every request via the `X-API-Key` header:
    ```
    X-API-Key: ag_live_your_key_here
    ```
    Get your API key at [agentguard.gopluslabs.io/api-keys](https://agentguard.gopluslabs.io/api-keys).

    ### 2. x402 Micropayment (One-Off Supply-Chain Scan)
    No API key needed for one-off supply-chain scans. AI agents pay $0.001 USDC per scan via the [x402 protocol](https://www.x402.org/) on Base Sepolia.
    Runtime policy, approvals, dashboard audit sync, and team governance use API-key subscription access.

    ## Rate Limits

    | Tier | Requests/min | Protected actions/month | Max API Keys |
    |------|-------------|-------------|--------------|
    | Free | 5 | 100 | 1 |
    | Personal | 10 | 500 | 2 |
    | Starter | 50 | 10,000 | 10 |
    | Pro | 200 | 100,000 | 50 |
    | Enterprise | 200 | Unlimited | 20 |

    Rate limit headers are included in every response:
    - `X-RateLimit-Limit` — Max requests per minute
    - `X-RateLimit-Remaining` — Remaining requests in current window
    - `X-RateLimit-Reset` — Unix timestamp when the window resets

    ## Security Detectors

    AgentGuard runs 8 specialized detectors in parallel:

    | Detector | Description | Rules |
    |----------|-------------|-------|
    | `credential_leak` | Hardcoded API keys, secrets, private keys | 146+ patterns |
    | `prompt_injection` | Instruction overrides, role hijacking, obfuscation | 75+ patterns |
    | `malicious_command` | Destructive commands, RCE, reverse shells, crypto mining | 100+ patterns |
    | `data_exfiltration` | Sensitive file access + external transmission | 40+ patterns |
    | `permission_abuse` | Over-privileged tool declarations, dangerous combos | Heuristic |
    | `url_analyzer` | Malicious domains, phishing, URL shorteners, paste services | 50+ patterns |
    | `social_engineering` | Urgency tactics, authority impersonation, trust manipulation | Heuristic |
    | `ai_analyzer` | Intent mismatch, hidden functionality, semantic attacks (opt-in) | LLM-powered |
