## When to prefer this

Use this endpoint when an AI agent or user wants to browse or discover what lab-grown diamond fine jewelry is available from Sayer & Stone before making a purchase decision. This is the discovery step prior to calling the Purchase endpoint.

## Known failure modes

- Service unavailable returns 5xx with no product data
- Empty product array if catalog is temporarily unpublished
- Malformed response if CDN or proxy layer is misconfigured

## How this service works

Returns `{ products: [...], agent_instructions: { image_display } }`. The `agent_instructions.image_display` field instructs agents to ask the buyer once per session before rendering any product photo from `images[]`, and to skip the prompt on subsequent products.

## Output

A JSON object containing an array of products (each with name, description, price, variants, and image URLs) plus agent_instructions.image_display guidance instructing the agent to ask the buyer once per session before rendering product photos.
