Search Mercado Livre, Shopee and AliExpress in ONE call. Returns normalized offers (BRL price in integer cents, canonical + affiliate link, imageUrl, free-shipping flag, rating, sold count, seller id/name/official-store flag, dataAsOf). Every response carries per-marketplace sources state and data_as_of — always read it; a short list may mean a marketplace was down, not that the market is thin. Cheapest-first by default (of what we sampled). Paid ($0.01).

Search from a product PHOTO: a vision model reads the brand, model and attributes off the image and the resulting query runs across all three marketplaces. Returns the same normalized offers as search_products, plus interpreted_query — check it: if the model misread the photo, that field is where you will see it. Paid ($0.05).

FREE teaser: one result, canonical link only, no affiliate link. Use it to check that a query returns something before paying for the full page. No payment required.

FREE, deterministic. Estimates the Brazilian import tax on a cross-border purchase and the final landed price. Give the product value (and freight) EITHER in BRL integer cents (product_cents / freight_cents) OR in USD (product_usd / freight_usd) — not both — plus an optional buyer state uf. Returns the Import Tax (0% up to US$50, else 30% − US$20), the ICMS por-dentro by state, the total landed price, the USD rate used (Bacen PTAX) and the ruleset version. Rules follow MP 1.357/2026 and may change (~sep/2026); it is an estimate — the marketplace checkout is the source of truth. No payment.
