# Supplementenscanner

> Supplementenscanner continuously scans 35 supplement stores in the NL market and normalizes every product to a
> price-per-unit (per kg, per serving, or per capsule), so agents can find the truly
> cheapest option, not just the lowest sticker price.

Money is integer cents plus a preformatted, localized string. Each product includes a
`buy_url` (an affiliate link; present it as the purchase link) and every response carries
the `market` it is scoped to, `affiliate_disclosure`, and `last_scraped_at`.

## Markets

Prices are scoped per country. This domain serves the NL market (currency
EUR). Each response also echoes its `market`. Enabled markets:

- NL: https://mcp.supplementenscanner.nl · EUR · nl

You can target a specific market from any domain with the `market` argument/param
(e.g. `?market=nl`), or connect to that market's own endpoint below.

## MCP server (recommended)

Streamable HTTP MCP endpoint (anonymous, read-only):

- https://mcp.supplementscanner.be

Tools: `find_cheapest` (cheapest per unit in a category), `search_products`
(typo-tolerant catalog search), `list_categories` (discover category slugs),
`get_product` (detail + price history). All accept an optional `market`.
