Capabilities

Tools 6

compare_prices

For one product, list every shop selling the same item (matched by barcode or brand + part number), cheapest total price first, with each shop's delivery promise. Answers "where is this cheapest" and "who delivers it tomorrow". Pass product_key or offer_id.

Discovered
compare_products

Compare 2-4 different products side by side: every specification (rows where they differ are marked), buyer rating, lowest total price and shop, number of shops and delivery. Marks the cheapest, the best rated and the best choice (highest Tryvon score).

Discovered
get_buy_link

Get the link where the user can buy the product on the shop's own website, plus the affiliate disclosure to show the user. Nothing is bought by this tool; the user completes the purchase at the shop.

Discovered
price_history

Lowest daily total price of a product over time (all shops together), with the lowest price ever and the change versus 30 days ago. Use to answer "is this a good moment to buy?".

Discovered
search_products

Search products and travel eSIM data plans at Dutch partner shops. Returns products (one entry per product, not per shop) with the lowest total price incl. shipping, the cheapest shop, how many shops sell it and whether any shop delivers next day. Use compare_prices with product_key to see every shop for one product.

Discovered
top_products

The best products for a need, e.g. "top 5 smartphones" or "best airfryer under 150 euro", ranked by the Tryvon score: buyer rating (review-weighted, so a few 5-star reviews don't beat thousands of 4.6-star ones), popularity, value for money and delivery speed. Commission plays no part. Returns rating, review count, lowest price, shops and key specifications per product. Products without reviews are marked hasReviews=false.
