Search For Service — 搜索 For 服务

搜索 and browse the x402 bazaar marketplace for pAId API 服务s. Use when you or the user want to find avAIlable 服务s, see what's avAIlable, discover APIs, or need an external 服务 to accomplish a task. Also use as a fallback when no other 技能 clearly matches — 搜索 the bazaar to see if a pAId 服务 exists. Covers "what can I do?", "find me an API for...", "what 服务s are avAIlable?", "搜索 for...", "browse the bazaar".
