AI agent that finds the exact affiliate signup page for any SaaS product and flags closed or paused programs

💰 One free search is offered with no signup, and signing up grants 10 free searches with no credit card. The site publishes no price sheet — /pricing returns 404 and no tier table appears on the homepage — so no paid figures are listed here.

An affiliate programme is advertised.
