IAE Product Architecture: Building a Sellable AI Agent with A2A Protocol and Modular Pricing

Most AI agent projects die as consulting engagements. Someone builds a custom workflow, charges hourly, and the moment they stop touching it, the client churns. The agent was never a product — it was a service wearing a product’s clothes.

I spent the last week turning our intelligence agent into something with a SKU. The result is the Intent Agent Engine (IAE): a two-layer architecture built on Google’s A2A Protocol, with modular pricing that lets customers buy exactly the capability they need. Here’s how the architecture decisions drove the pricing, and why the obvious approach — one agent, one price — would have killed the business.
