is-real-biz
Plugs into Claude to verify if a domain belongs to a real business in under two seconds. Returns a verdict (real, likely_real, uncertain, likely_fake, fake), trust score, and supporting evidence pulled from RDAP records, SSL certificates, homepage classification via Gemini Flash, and contact info presence. Reach for this when screening vendors, qualifying leads, or running fraud checks on domains an agent encounters. Ships with two payment options: x402 for autonomous micropayments with no signup, or prepaid credits starting with 50 free checks. Runs on Cloudflare Workers with D1 and KV for 24-hour caching. The tool descriptions are written for embedding-based selection, so agents using natural language queries will surface it reliably.
