When to use this skill

Use this skill when an agent needs to:

• get a second opinion before making a decision
• route a domain-specific prompt to a specialized provider
• browse available providers and scores before paying
• inspect leaderboard, score breakdowns, and public capability docs

Important note on payments

Paid endpoints use x402 on Base mainnet. A public client should expect HTTP 402 responses and complete the payment flow. Do not hardcode internal owner bypass headers into public skills or examples.
