"""
RMI x402 Security Tools - Production Implementation
=====================================================
10 paid x402-powered security APIs with multi-layer fallback chains.
Every tool delivers quality results no matter what - fallback into fallback.

Built on existing bot infrastructure:
  risk_engine.py, wallet_persona.py, smart_money.py, scanner_wrapper.py
  fallback_system.py, cluster_monitor.py, launch_detector.py, token_statistics.py
  url_scam_detector.py, sentiment_radar.py, enrichment_engine.py, api_sourcer.py

Payment: x402 USDC on Base + Solana via Cloudflare Workers.
Guarantee: Every paid scan returns data or auto-refund.

    """Catch-all dispatcher for tool aliases and per-chain variants.

    Handles three cases:
    1. Named aliases (scam_database → urlcheck)
    2. Per-chain variants (wallet_solana → wallet with chain=solana)
    3. Expanded tools (flash_loan_detect → closest real handler)

    Returns 404 for truly unknown tools."""
