Marketplace Search

This is a sprawling utility belt that connects Claude to 15+ marketplace APIs, government databases, and verification services through 22 tools. You get unified search across TCGPlayer, Reverb, Grailed, Craigslist, and others, plus specialized lookups for contractor and nurse licenses in multiple states, NYC building violations, GSA auctions, FCC certifications, and childcare cost data by ZIP code. It even includes PSA card population reports and a SkillGuard safety verification tool. The breadth is impressive but scattered. Reach for this when you need to query niche data sources that would otherwise require separate integrations, or when you're building workflows that span e-commerce, compliance checks, and public records.
