check_url ~373 tokens
Paid Agent Preflight URL check ($0.005 USDC on Base). Call before an agent opens, follows, downloads from, or trusts an unknown URL.

preflight_action ~1216 tokens
Agent Action Gate ($0.02 USDC flat; stable MCP tool name preflight_action). Use before an AI agent performs an external action.

Paid Agent Tool Router ($0.002 USDC on Base). Finds and ranks machine-payable MCP services and x402 HTTP endpoints before your agent chooses or pays a provider.
