# 100one
> Price-comparison catalog for cordless power tools (US market). We aggregate products and link out to retailers; we do not sell directly.

## Machine-readable API
- GET /api/categories — list of categories
- GET /api/products?category=ID — products (optionally filtered by category)
- GET /api/product/ID — a single product with all seller offers and price history
- GET /sitemap.xml — all indexable URLs
- GET /api/openapi.json — OpenAPI 3 spec (MCP-ready tool integration)

All product pages embed schema.org Product/Offer/AggregateRating JSON-LD.
Prices include a checkedAt timestamp; treat stale prices as advisory and verify at the retailer URL.

## Notes for agents
- Each product lists multiple seller offers with price + url. The cheapest in-stock offer is "bestPrice".
- "platform" is the battery ecosystem (e.g. DeWalt 20V MAX). Batteries are not cross-compatible between platforms.
