Find Alibaba supplier / manufacturer listings for a query (via Serper site:alibaba.com) — returns title + rating + a supplier snippet + the Alibaba link. TEXT ONLY: no price or photo are available via this source (the user sees price / MOQ / photos on Alibaba after clicking).

Show which sellers have been winning the buybox for an ASIN over time, AND how the competing-seller pool has changed month over month. Returns a per-week breakdown of buybox winners; a monthly distinct-seller-count series (seller_count_monthly, trailing ~6 months) plus a seller_trend label (stable/rising/falling) so you can say whether the seller pool is stable or volatile (more sellers piling on vs consolidating); plus the ASIN's product brand, title and price (or price range) and its fulfillment (FBA/FBM/AMZ). Use when the user asks 'who has been winning buybox on this ASIN', 'buybox history for B08N5WRWNW', 'seller rotation', 'has the buybox owner changed', 'is the seller pool stable or volatile', 'are more sellers piling onto this listing', or any ASIN buybox/seller timeline.

Find ASINs similar to a given ASIN by brand, price band, and seller count. Use when the user asks 'ASINs like this one', 'similar products', 'comparable ASINs', 'what else is like B08N5WRWNW', or any ASIN-level lookalike question. Each comparable carries product brand, title, price (or price range) and fulfillment (FBA/FBM/AMZ + amz/fba pct).

Estimate whether an ASIN can hit a target profit margin given current buybox price, estimated FBA fees, and Amazon referral fee. Use when the user asks 'can I make money on this ASIN', 'profit calculator', 'margin estimate for B08N5WRWNW', 'is this ASIN profitable to sell', or any margin/profit question. Also returns product brand, title, price (or price range) and fulfillment (FBA/FBM/AMZ + amz/fba pct) for the ASIN.

List the saved authorized sellers for a brand. Use when the user asks 'who are my authorized sellers for X', 'show my approved resellers', 'what's my whitelist for this brand'.

Save the authorized sellers for a brand you own/manage — the whitelist that makes 'unauthorized seller' detection possible. The brand must already be tracked in this workspace. Use when the user says 'these are my authorized sellers for X', 'add Y to my authorized list', 'set my brand's approved resellers'. Pass the seller names exactly as they appear on Amazon.

Show how a brand's buybox concentration has changed over time. Returns weekly seller counts and observed buybox days for the trailing window. Use when the user asks 'is this brand getting more competitive', 'concentration trend for Nike', 'how has seller count changed over time', or 'buybox trajectory'.

Show ASINs that recently appeared for a brand. Use when the user asks 'new products for Nike', 'recently added ASINs', 'what new listings does this brand have', or any question about a brand's recent catalog additions. Each ASIN carries product brand, title, price (or price range) and fulfillment (FBA/FBM/AMZ + amz/fba pct).

Find brands similar to a given brand by category, price tier, and competition level. Use when the user asks 'brands like Nike', 'similar brands to source', 'show me comparable brands', 'what else is in this niche', or any cohort/lookalike question.

Detect whether a brand is under competitive attack: an elevated NEW-ENTRANT RATE (brand-level newly-observed sellers vs the trailing-month baseline) combined with buy-box churn. Uses brand-level first-seen (a seller's first observation anywhere across the brand's ASINs), which is stable under scraper-coverage growth — not the inflated per-ASIN count. Use when the user asks 'is my brand being targeted', 'brand under attack', 'new sellers flooding my listings', 'is someone targeting this brand'.

Check whether a brand sells on Amazon US, Amazon UK, and/or Walmart. Returns per-marketplace seller count, ASIN count, observed buybox days, and control score. Use when the user asks 'does this brand sell on Walmart', 'cross-marketplace presence for Nike', 'is this brand on Amazon UK', or any multi-marketplace brand question.

Find brands that recently gained the most newly-OBSERVED sellers (sellers whose first-seen date on the brand falls in the window) — an observation signal, NOT confirmed market entry (sparse re-sampling can resurface long-present sellers as 'new'). Optional category filter. Use when the user asks 'brands gaining sellers in [category]', 'brands under hijacker pressure', 'who is seeing new entrants this month', or category-scoped seller-growth signals without naming a specific brand.

Find brands that share operators/sellers with a target brand. Returns brands ranked by how many operators they share. Use when the user asks 'what brands are in X's network?', 'brands related to Ninja', 'who else do Ninja's sellers carry?', 'brands in the same seller network', or 'brand family'. This reveals the operator graph — brands connected through shared distribution channels.

Find the ASINs where a brand you own has LOST the buy box to a seller outside your authorized list — ranked by estimated revenue at stake — so you can act on the costliest first. Each flagged ASIN carries its product brand, title and price (or price range) plus its fulfillment (FBA/FBM/AMZ). Save your authorized list first (authorized_seller_set) for precise flagging; without it, ASINs where a third-party operator holds the buy box are flagged. Use when the user asks 'where am I losing the buy box on <brand>', 'buy-box loss on my ASINs', 'which of my listings did I lose'.

Find categories where Amazon is retreating — net brand exits exceed entries over 90 days (amazon_expansion_net_90d < 0). Returns categories ordered by retreat magnitude. Use when the user asks 'where is Amazon pulling back?', 'which categories is Amazon leaving?', or 'Amazon retreat opportunities'.

Return the full metric set for ONE category at any depth — a root OR a sub-category niche like 'Terrariums'. Covers demand (30-day revenue, units, velocity tier), competition (heat, diversity, brand/ASIN/seller counts), Amazon presence (retail dominance, private-label share, FBA penetration, 90-day brand expansion), price, ship-by days, and close-outs. Use for 'show me the metrics/stats for category X', 'how big is the X category', or to pull the numbers behind a niche question.

Find brands newly OBSERVED in a category — the first date our daily sampling saw the brand there falls in the window. An observation signal, NOT confirmed first-ever entry (sparse re-sampling can resurface a long-present brand as 'new'). Use when the user asks 'new brands in Electronics', 'what brands just entered this category', 'emerging brands in Toys', 'category new entrants'.

Find brands in a category with the biggest recent growth in seller count and observations. Use when the user asks 'fastest growing brands in Toys', 'top growers in this category', 'which brands are trending up', or any category-scoped growth question.

Find specific BRANDS within a category that have proven multi-seller demand but are still under-competed (a min-seller floor drops single-seller / brand-owner-only listings). Returns BRANDS — not niches or sub-categories. Use for 'undercompeted brands in <category>', 'low competition brands in Toys', 'which brands can I source in <category>'. Do NOT use for 'under-served niches', 'niches in <category>', or 'find a niche to enter' — those are SUBCATEGORY questions; use find_underserved_niches instead.

Pull a LIVE, on-demand snapshot of a single Amazon ASIN right now — current title, price, live offers and the sellers on the listing today — and return it alongside Webotee's historical brand and seller intelligence, including the ASIN's product brand, title and price (or price range) and its fulfillment (FBA/FBM/AMZ). Use when the user gives a specific ASIN and wants its CURRENT/today's data rather than the pre-collected dataset (e.g. 'check ASIN B0... right now', 'who's on this listing today and at what price'). Amazon US only; one ASIN per call.

Map the competitive landscape for a brand or category root. Returns top 10 sellers by observed buybox days held, top 10 brands by winner-diversity HHI, plus week-over-week deltas. Use when the user asks 'who's winning this category?' or 'who controls the buybox here?'.

Evaluate a single ASIN for FBA sourcing. Returns composite sourcing score (0-100), 5-dimension breakdown (velocity, gating, friction, margin, brand_posture), estimated 30-day demand (units_30d_final + est_revenue_30d) with its source/badge_band/confidence, a data_coverage flag (full vs velocity_only — so a null demand reads as a coverage gap, not zero sales), star rating + review count (with a rating_coverage flag), brand-level FBA/Amazon dominance, and a red-flag list. Also returns the product brand, title, and price (or price range) plus the ASIN's fulfillment (FBA/FBM/AMZ + amz/fba pct). Use when the user asks 'should I buy this?', 'how fast does this sell?', or shares an ASIN and wants a sourcing recommendation.

Evaluate a brand for portfolio inclusion. Returns brand-level control posture, winner diversity (HHI), Amazon retail dominance %, FBA penetration %, catalog churn rate, total bought-past-month volume, estimated 30-day revenue, avg ship-by days, cross-brand operator count, plus the top 10 ASINs by composite sourcing score (each with product brand, title, price or price range, and fulfillment FBA/FBM/AMZ + amz/fba pct). Use when the user names a brand and asks 'is this worth carrying?', 'how does this brand look?', 'what is the churn rate?', or 'how fast does this brand ship?'.

Assess whether a category or niche (ANY depth — e.g. 'Terrariums') is winnable for a NEW private-label brand. Use for 'is X winnable for private label', 'should I private-label X', 'is the X niche good for a new brand', 'can I launch my own brand in X'. Returns a per-signal pass/fail breakdown and a Strong / Moderate / Weak verdict based on Amazon's footprint, seller fragmentation, demand, and price band.

Return brands whose FBA buybox share is below or above a threshold. FBA share is computed as fba_buybox_days / total_buybox_days * 100 (percentage, 0-100). Use fba_share < 40 to find FBM-heavy brands (carriers hold real inventory) or fba_share > 80 for FBA-dominated brands. Supports sort by control_score (heat), unique_sellers, or brand_bought_past_month_30d.

Return operators whose FBA buybox share is below or above a threshold. FBA share is 0-100 (percentage). Use fba_share < 50 to find FBM-leaning operators (likely carrying real inventory) or fba_share > 80 for FBA-heavy flippers. Supports optional brand filter to narrow to operators selling a specific brand.

Find brands experiencing high seller churn relative to their category. Returns brands where seller_churn_30d_delta_vs_cat_pp >= the specified threshold (default 5pp). Optionally filtered by category. Use when the user asks about 'brands losing sellers', 'high churn brands', or 'seller instability'.

Find brands where buybox concentration dropped over the last quarter — more sellers are entering, creating opportunity for new entrants. Use when the user asks 'brands losing control', 'deconcentrating brands', 'brands opening up to competition', 'gentrification opportunities', or any question about brands becoming less monopolized.

Find operators (sellers) we FIRST OBSERVED selling recently — their earliest observation in our data falls in the window. An observation signal, NOT confirmed market entry: sparse sampling can surface a long-present seller the first time we see them. Different from top_expanding_operators (existing operators adding brands). Use when the user asks 'new sellers this month', 'who just started selling', 'newly seen operators', or any question about emerging/newly-observed sellers.

Find where one product sits across the open web — a live cross-retailer price check — with every price anchored to Webotee's independently-observed Amazon buy-box. Give ONE identifier (asin, upc, gtin, or title + brand) and a mode: price_compare (default, all retailers vs the Amazon buy-box), cheaper (only sources below the buy-box), dropship (net margin after estimated Amazon fees), or supplier (wholesale-class sources). Returns each source's price, class, spread vs the buy-box, and a durability read from our 16-month history. The Amazon anchor also carries the product brand, title, and price (or price range) plus its fulfillment (FBA/FBM/AMZ + amz/fba pct). One product per call.

Find brands where a single operator controls 100 percent of observed buybox days. These are either gated/exclusive or operator-acquired brands. Use when the user asks 'brands with one seller', 'exclusive brands', 'single-seller brands', 'monopoly brands', or any question about brands with no competition.

Given an Amazon ASIN, diagnose its business model (private-label / wholesale / arbitrage) and find real-world supplier, wholesale and arbitrage matches across the web, then return an HONEST sourcing read: a viability qualifier (green/yellow/red), the specific move + required differentiation, conservative economics, named risks (IP, tariffs, MOQ, saturation, gating, dropship policy) and validation steps. A credible lead generator, not get-rich advice. Scout+.

Find brands with low seller competition but real sales presence. The flagship sourcing discovery tool. Use when the user asks 'find brands with few sellers', 'low competition brands', 'undercompeted brands under $50', 'brands I could source with little competition', or any variant of 'find me something to sell'. Pass seed_brand when user mentions a reference brand ('brands like Ninja', 'low competition in the same category as OXO') to constrain results to the same root category.

Find UNDER-SERVED NICHES — real SUBCATEGORIES with genuine demand but room to compete, ranked by private-label winnability from 2-year marketplace data. Returns CATEGORIES / sub-categories (e.g. 'Wireless Earbuds', 'Cable Organizers'), NEVER brands. This is the RIGHT tool for ANY niche-discovery question: 'under-served niches', 'niches in <category>', 'find a niche to enter', 'what niche should I sell in', 'underserved categories', 'gaps in <department>', 'where's the opportunity in <category>'. When the user names a department or category (e.g. 'electronics', 'home & kitchen'), pass it as category_name to scope the niches to that area. Do NOT use category_undercompeted_brands or find_undercompeted_brands for niche questions — those return BRANDS, not niches.

Recommend ungate / arbitrage / avoid for an ASIN, with a 3-bullet rationale citing named metrics (gating_score, amz_retail_dominance_pct, fba_pct, brand_posture). Also returns the ASIN's product brand, title and price (or price range) plus fulfillment (FBA/FBM/Amazon). Use for 'should I try to ungate this?' / 'how should I price this?'.
