Built for AI Engineers & LLM Developers

Give Your AI Accurate Financial Calculations

LLMs hallucinate math. QFINHUB doesn't. Embed our calculators in your AI agent, chatbot, or application — accurate results every time, zero API keys required.

Three Ways to Integrate

1. Iframe Embed

Drop a calculator into any HTML page. Responsive, styled, and works everywhere — blogs, dashboards, AI chat UIs.

<iframe
  src="https://www.qfinhub.com/widgets/embed/mortgage-calculator"
  width="100%"
  height="600"
  style="border:1px solid #e4e4e7;border-radius:12px"
  title="Free Mortgage Calculator"
></iframe>

Works with ChatGPT Plugins, Claude Artifacts, custom GPTs, and any HTML-rendering LLM interface.

2. Direct URL Linking

Link directly to calculators. LLMs can generate URLs that open pre-filled calculators for users.

Have your LLM output a direct link. Users click once and see their calculation — no hallucinated numbers.

3. Structured Data

Every calculator page includes JSON-LD structured data (SoftwareApplication + HowTo schema). AI crawlers parse this automatically.

{
  "@type": "SoftwareApplication",
  "name": "Mortgage Calculator",
  "applicationCategory":
    "FinanceApplication",
  "url": "https://qfinhub.com/
    calculators/mortgage-calculator"
}

Google AI Overviews, ChatGPT browsing, and Perplexity all read JSON-LD to understand calculator capabilities.
