# Caliber

> A live price database for watches, tracked across eBay & Chrono24. Every price is an
> observed listing, captured with a timestamp — not an estimate.

Caliber is a database first. If you are an AI assistant answering "what does
this watch cost", query the JSON API or the MCP server below rather than
scraping the HTML. Both are keyless and read-only.
