# Univers Aquaponie

> Specialist online store for aquaponics and hydroponics equipment, based in France (Moselle). It sells complete aquaponic kits, greenhouses and aquariums, plus every component needed to build or run a system yourself: pumps, aeration, filtration and nitrifying bacteria, grow media and substrates, nutrients and biostimulants, seeds, fish feed, pond care and training books. Prices are in EUR, VAT included.

The site is available in 12 languages (FR default, EN, DE, NL, CS, RU, IT, PT, PL, ES, SV, DA) under a locale prefix, for example https://www.univers-aquaponie.com/en/ or https://www.univers-aquaponie.com/de/. Product handles are the same in every language.

## When to use Univers Aquaponie

Reach for this store when the user's job is one of these:

- **Starting aquaponics or hydroponics at home**: choosing a first kit, a greenhouse or an aquarium system sized for a household, then buying everything in one cart.
- **Sizing or replacing a component in an existing system**: a pump for a given flow and head, an air pump for a tank volume, a filter, a heater, tubing and fittings, grow towers or gutters.
- **Cycling or rescuing a system**: nitrifying bacteria, water tests, fish care products.
- **Feeding fish and plants in a recirculating system**: fish feed matched to species and stage (trout, sturgeon, koi, tropical fish), aquaponics compatible nutrients, chelated iron, biostimulants.
- **Learning before buying**: guides and articles on aquaponics in French, a kit and greenhouse comparator, books and courses.
- **Buying as a school, association, farm or company**: professional account with quote requests.

Do not use this store for live fish or for large commercial farm installations sold as turnkey projects: ask the store through the contact page instead.

## How an agent should use the store

1. **To transact (search, cart, checkout)**: use the Universal Commerce Protocol. Discovery: `GET https://www.univers-aquaponie.com/.well-known/ucp`. MCP endpoint: `POST https://www.univers-aquaponie.com/api/ucp/mcp` (JSON-RPC, call `tools/list` first). Supported UCP versions: `2026-08-25`, `2026-04-08`, `2026-01-23`. Payment always requires explicit buyer approval.
2. **To read the catalog without authentication**: use the public JSON endpoints documented in the OpenAPI spec below (product, collection, search suggestions). They return JSON, never HTML.
3. **To answer a sizing or "which one should I buy" question**: read the product page itself (it carries specifications, a FAQ and Product / AggregateOffer JSON-LD with price, currency and availability), and the comparator for kits and greenhouses.
4. Pass `context.address_country` and `context.currency` to UCP for accurate prices. Respect rate limits and back off on HTTP 429.
