The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
calculate_import_taxes Estimate Brazilian import tax & landed price (free) ~323
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.
| Name | Type | Req | Description |
|---|---|---|---|
| freight_cents | integer | – | Freight in BRL cents (part of the customs base). |
| freight_usd | number | – | Alternative: freight in USD. |
| insurance_cents | integer | – | Insurance in BRL cents, if any. |
| insurance_usd | number | – | Alternative: insurance in USD. |
| product_cents | integer | – | Product value in BRL cents (e.g. 30000 = R$300). Use the *_cents fields OR the *_usd fields, not both. |
| product_usd | number | – | Alternative: product value in USD (e.g. 59.90). |
| uf | string | – | Buyer's 2-letter Brazilian state (e.g. SP). Default: 20% ICMS ceiling. |

search_brazilian_marketplaces Search & compare products across Brazilian marketplaces (free) ~405
FREE — no wallet needed. 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). Best-effort per-IP rate limit; identical repeated queries come from a 10-minute cache and are not counted. ⚠️ It is free because brmarket earns the AFFILIATE COMMISSION on what the user buys — show `affiliateUrl` when an offer has one.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Results in the merged page. Default 10, max 20. |
| marketplace | array | – | Restrict the search to these marketplaces. Default: all three. |
| max_price | number | – | Maximum price in BRL. |
| min_price | number | – | Minimum price in BRL (e.g. 199.90). |
| q | string | yes | What to search for, e.g. 'iphone 14 pro'. |
| rerank | boolean | – | Opt-in LLM relevance pass (~400ms, free). Turn it ON whenever the query has a cheaper accessory, part or homonym: it drops offers that merely contain the words (a coffee FILTER for 'cafeteira', an Ai… |
| sort | string | – | Default price_asc (cheapest first). |
| uf | string | – | Buyer's 2-letter Brazilian state (e.g. SP), for the ICMS rate in landed-price estimates. Default: 20% ceiling. |
No output schema declared.

search_by_image Search Brazilian marketplaces from a product photo ~335
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_brazilian_marketplaces, plus `interpreted_query` — check it: if the model misread the photo, that field is where you will see it. Paid ($0.05) — this one runs a vision model, which costs us real money per call.
| Name | Type | Req | Description |
|---|---|---|---|
| image_url | string | yes | Public https URL of the product photo. JPEG/PNG/WebP, max 5MB. |
| limit | integer | – | Results in the merged page. Default 10, max 20. |
| marketplace | array | – | Restrict the search to these marketplaces. Default: all three. |
| max_price | number | – | Maximum price in BRL. |
| min_price | number | – | Minimum price in BRL (e.g. 199.90). |
| rerank | boolean | – | Opt-in LLM relevance pass (~400ms, free). Turn it ON whenever the query has a cheaper accessory, part or homonym: it drops offers that merely contain the words (a coffee FILTER for 'cafeteira', an Ai… |
| sort | string | – | Default price_asc (cheapest first). |
| uf | string | – | Buyer's 2-letter Brazilian state (e.g. SP), for the ICMS rate in landed-price estimates. Default: 20% ceiling. |
