Tools

Three MCP tools are available. All are read-only and require no authentication.

search_products — Semantic Search

Natural language search using vector embeddings. Understands intent, synonyms, and context across Czech, Slovak, German, Polish, Hungarian, Romanian, and English.

When to use: Open-ended queries, gift ideas, category browsing, intent-based search.

Returns: Products ranked by semantic relevance score (0-1). Includes title, description, price, currency, brand, category, gtin, image_url, product_url, availability, eshop info, and cart_action.

Parameter	Type	Required	Description
query	string	Yes	Natural language search query
origin_country	string	No	E-shop country: CZ, SK, PL, HU, RO, DE, AT
target_country	string	No	Target market filter
min_price	number	No	Minimum price (set currency too)
max_price	number	No	Maximum price (set currency too)
currency	string	No	ISO 4217: CZK, EUR, PLN, HUF, RON
brand	string	No	Exact brand name (case-sensitive)
category	string	No	Category keyword match
availability	string	No	in_stock, out_of_stock, preorder
eshop_domain	string	No	Filter by e-shop domain
limit	integer	No	Results count, 1-50 (default 10)
fields	list	No	Fields to include (saves up to 70% tokens)

search_products_by_text — Keyword Search

Exact keyword matching in product titles. Deterministic results, faster than semantic search.

When to use: Known product names, model numbers, brand + product combinations.

Returns: Products matching all keywords. Same fields as semantic search (without score).

category	string	No	Category keyword match
origin_country	string	No	E-shop country: CZ, SK, PL, HU, RO, DE, AT

min_price	number	No	Minimum price (set currency too)
max_price	number	No	Maximum price (set currency too)
currency	string	No	ISO 4217: CZK, EUR, PLN, HUF, RON
limit	integer	No	Results count, 1-50 (default 10)
fields	list	No	Fields to include (saves up to 70% tokens)

lookup_by_gtin — GTIN/EAN Barcode Lookup

Exact barcode match. Finds all e-shops selling a product by GTIN/EAN/UPC.

When to use: Price comparison by barcode, product identification.

Returns: All products matching the barcode. Same fields as keyword search.

Parameter	Type	Required	Description
gtin	string	Yes	GTIN/EAN/UPC barcode (8-14 digits)
origin_country	string	No	E-shop country: CZ, SK, PL, HU, RO, DE, AT
target_country	string	No	Target market filter
limit	integer	No	Results count, 1-50 (default 10)
fields	list	No	Fields to include (saves up to 70% tokens)

Usage

Semantic search — natural language, understands intent

curl "https://shoptera.ai/api/v1/search?q=dárek+pro+zahradníka+do+500+Kč&max_price=500&currency=CZK&origin_country=CZ"

Keyword search — exact title matching, fast

curl "https://shoptera.ai/api/v1/search/text?title=Nike+Air+Max+90&brand=Nike"

GTIN/EAN lookup — find e-shops by barcode

curl "https://shoptera.ai/api/v1/search/gtin/5901234123457"

Saving tokens — return only the fields you need

curl "https://shoptera.ai/api/v1/search?q=boty&limit=5&fields=title,price,product_url,cart_action"

Cart actions

Every product includes a cart_action object:

• method: "GET" — navigate to url to add the product to cart automatically
• method: "browser_click" — navigate to url, then click the button matching button_text
• method: "view_product" — show the product page URL to the user

---

Capabilities

• Product Search — semantic vs keyword vs GTIN, when to use which, filters, scoring
• Cart Actions — three action types, how to handle each
• Data Coverage — countries, data freshness, live stats

Privacy Policy

Shoptera Product Intelligence is a read-only product search service. We do not require authentication, do not collect personal data, and do not process payments.

• No personal data collected — no accounts, no cookies, no tracking pixels
• Query logging — we log anonymized search queries (without IP addresses) for service improvement and aggregate usage statistics
• No data sharing — query logs are not shared with third parties
• Rate limiting — IP addresses are used transiently for rate limiting (300 req/hour) and are not stored
• Product data — all product information is sourced from publicly available e-shop feeds
• Cart actions — purchase redirects go directly to the original e-shop; Shoptera does not intermediate transactions
