For agents & developers

Let your AI agent read the whole supplement market

We continuously scan 13 stores and convert every price to a price per unit. Give Claude, ChatGPT or your own AI agent direct access via MCP or our JSON API to the lowest price per unit in every category: normalised, up to date and ready to cite.

Good to know

Amounts are whole cents (*_cents) plus a localised string you can display verbatim, e.g. “€ 12.48 per kg”.
Compare products on unit_price_cents for the normalised price per unit.
Every product includes a buy_url: show it as the purchase link. It is an affiliate link, so include the provided affiliate_disclosure alongside it.
Both channels are rate-limited per IP; no key required.
