Your API ranks on Google. But does it rank for AI agents?

I asked Perplexity "what is the cheapest price API for AI agents?" - and got back three competitors, none of them me. My API was ranking for humans. Invisible to agents. Here's the three-layer fix. I'm building AgentShare solo from Vietnam - a price/offer data layer for AI agents. The whole point of the product is being agent-readable, so failing the "can an AI find me" test was a wake-up call. This article is the receipt: what I implemented, what each layer is for, and what changed. The mental model: three layers, not one Most "SEO for APIs" articles stop at sitemap + meta.
