CallAI: SEO data, AI models & one-click apps. Pay in USDT or card

Hi Product Hunt 👋 I built CallAI because tools like Ahrefs and Semrush start at $129/month, and most site owners I know only need them a few times a month. CallAI does three things: 1. Pay per use. Keyword, SERP and backlink lookups, AI calls and servers are billed at actual usage. Top up from $1; the balance never expires. 2. Low friction. Sign up with just an email: no phone number, no ID check. Pay with USDT or card. 3. Ready-made apps, not just raw APIs. Competitor keyword gaps, domain vetting and 301 mapping pipelines, plus one-click WordPress / WooCommerce / Coolify servers placed on the cheapest cloud provider in your region. Try the free tools without signing up: AI rewriter, product description generator, cold email writer with a spam-word check, robots.txt and llms.txt checkers. Honest limits: new accounts start at $0 (no free credits), and a few one-click apps are not yet tested end to end by us; they are labelled in the app list. I'd love your feedback on what to build next.
