| wintraits_atributos_ganadores | Which attributes do winning products have? What should my product or listing include? (¿Qué atributos tienen los productos que triunfan? ¿Qué debe llevar mi producto o mi ficha?) Match categories (see wintraits_categorias_disponibles, `disponibles`; e.g. serums on Amazon Spain): attributes and 2-3 attribute combinations that set the winning launches of a category apart. For Scan-only categories use wintraits_scan_perfil. Useful beyond Amazon too: to design a product, brief a manufacturer or write the page of an own shop or another marketplace (measured on Amazon: a reference, not proof elsewhere). Each row has the lift (how many times more frequent among winners), the lift when checked against products launched later, the products behind it and the share of products with that attribute that end up winning. `tramos` explains what "bajo" (low), "medio" (medium) and "alto" (high) mean for numeric variables. On the free plan you see the attribute with the most effect and how the strongest combination starts (`combinacion_mas_fuerte`); `bloqueado` says how many more the full list has and `acceso` which view was used. Args: categoria: subcategory (see wintraits_categorias_disponibles; e.g. "serums"). pais: country code (see wintraits_categorias_disponibles; e.g. "ES"). max_resultados: rows per list (1-50). lang: "es" (default) or "en" (attribute names in English). Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027). | Not declared |
| wintraits_buscar_categoria | Find the category code from words: "air fryer", "juegos de mesa", "vitamin C serum", "puzzles". (Busca el código de una categoría a partir de palabras, en español o en inglés.) Call it before any other tool when you do not know the exact `categoria`: never guess codes. Returns up to 15 matches, best first, with `categoria` and `pais` (pass them as they come to the other tools), the name, `nivel` ("match": every tool; "scan": wintraits_scan_perfil, wintraits_ranking, wintraits_chequeo_rapido, wintraits_chequeo_asin) and the link. With no match, use wintraits_categorias_disponibles. Args: texto: what the user sells or wants to sell, in Spanish or English. pais: preferred country code ("ES", "FR", "DE", "IT"); matches in that country come first. lang: "es" (default) or "en". Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027). | Not declared |
| wintraits_categorias_disponibles | Categories and countries covered by Wintraits (valid values of `categoria` and `pais`). Call it first. `disponibles`: Match categories (`nivel` "match", with `estado_examen`): every Match tool works. `solo_scan`: Scan categories (snapshot of today's best sellers, with `fecha_datos`): wintraits_scan_perfil (winning attributes), wintraits_scan_historia, wintraits_chequeo_rapido and wintraits_chequeo_asin. New Scan categories every week. The data comes from Amazon, but the attributes also help outside Amazon (own shop, other marketplaces, product design, packaging). Args: lang: "es" (default) or "en". Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027). | Not declared |
| wintraits_chequeo_asin | Quick check of an Amazon listing by its ASIN or product link: we read the public listing, detect its Scan category and return the same as wintraits_chequeo_rapido. (Chequeo rápido de una ficha de Amazon por su ASIN o enlace.) `ficha_leida` gives the ASIN, the detected category and where its price sits against the middle half of best sellers (`por_debajo`, `dentro`, `por_encima`). The listing's text and price are not returned. If the product is not in a category with Scan published, it returns an error with the available categories: then use wintraits_chequeo_rapido with the pasted listing and the closest category. Args: asin_o_enlace: ASIN (10 characters, e.g. "B0XXXXXXXX") or Amazon product link (its country wins over `pais`). pais: country code when only the ASIN is given (default "ES"). lang: "es" (default) or "en". Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027). | Not declared |
| wintraits_chequeo_rapido | Does my listing have what today's best sellers have? Quick check of a listing, a technical sheet or a draft. (¿Tiene mi ficha lo que tienen hoy los más vendidos de mi categoría?) Every Scan category (`solo_scan` in wintraits_categorias_disponibles; use wintraits_buscar_categoria to find the code): a snapshot of today's best sellers against the rest, not a prediction. `indice_scan` is the Wintraits Scan Index (0-100: how much of the best sellers' distinguishing traits the listing has, weighting the top-ranked sellers more; 100 = the most complete best-seller listing today; `puntos` is the raw 0-100 score before that scaling; only the traits readable from the listing count), with the middle half of best sellers and of the rest (out of sample); null if fewer than 3 traits can be read. `zona` says where it falls: "mas_vendidos" (best sellers' zone), "entre" (in between), "resto" (the rest's zone) or "por_encima" (well above the best sellers: it mentions more traits than usual, and adding more does not bring it closer to them; never present it as better than the best sellers). Always name it "Wintraits Scan Index" with its best sellers' band (`texto`); give the user its `frase` and `zona_frase`; `metodo` links to how it is computed. `cifras` gives, for images, bullets, title and description length and price, the listing's value (`tu_ficha`) next to the median and middle half of best sellers and of the rest. Each trait says how often it appears among best sellers and the rest, and `lo_tiene` = true/false if it can be read from the listing, null if the user must check it. `te_faltan` lists the listing traits more frequent among best sellers that the listing lacks. `indice_scan.partes` splits the index into producto and presentacion (null with a `motivo` when it cannot be computed, never 0). The listing does not need to be on Amazon: a draft or the page of another shop works too. Match categories (`disponibles`) also accept it, but wintraits_diagnosticar_producto gives more. Args: titulo: listing title. categoria: Scan category id (e.g. "hidratantes"; see wintraits_categorias_disponibles). pais: country code (e.g. "ES"). vinetas: bullet points of the listing. descripcion: listing description. num_imagenes: number of images, if known. video: whether the listing has a video, if known. precio_eur: selling price in euros, if known. ficha_tecnica: technical sheet text (no online listing), used when `titulo` is empty: only the product part of the index is computed; `partes.presentacion` comes with valor null and motivo "sin_ficha_de_tienda". lang: "es" (default) or "en". Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027). | Not declared |
| wintraits_comparar_fichas | Which version of my listing is better? Compares two listings of the same category. (¿Qué versión de mi ficha es mejor?) Returns the diagnosis of each one (`a` and `b`), the difference in Wintraits Match Index points, a conclusion and the attributes read that differ between them. On the free plan both are shown in the free view. Args: ficha_a: {"titulo", "precio_eur", "num_imagenes", "vinetas", "descripcion", "volumen_ml"} of the first. ficha_b: the same for the second (e.g. another version of the same listing). categoria: subcategory (see wintraits_categorias_disponibles; e.g. "serums"). pais: country code (see wintraits_categorias_disponibles; e.g. "ES"). lang: "es" (default) or "en" (attribute names in English). Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027). | Not declared |
| wintraits_diagnosticar_producto | Why isn't my product selling? What should I change in my listing? (¿Por qué no vende mi producto? ¿Qué cambio en mi ficha?) Match categories (`disponibles`). Diagnoses a product listing (Amazon, an own shop, another marketplace or a draft): Wintraits Match Index (similarity to winners, 0-100, not a sales probability; always call it by that name, `indice_match.texto`), the changes that raise it most and the winning combinations within reach (missing one or two elements). On the free plan you see the first changes; `bloqueado` says how many more the full report has and `acceso` which view was used. Optional `atributos`: if you (the AI) read the listing yourself, call wintraits_opciones_concepto first and follow its `instrucciones_extraccion`: use only what the listing says (never deduce), exactly the keys of `atributos` and, for lista/categoria, only their `valores`; omit anything the listing does not say (we read it from the text). Invalid keys or values return an error with the valid options. Args: titulo: listing title. precio_eur: selling price in euros. num_imagenes: number of images in the listing. vinetas: bullet points of the listing. descripcion: listing description. volumen_ml: volume in ml, if not in the text. atributos: optional {key: value} read from the listing (keys and values from wintraits_opciones_concepto). categoria: subcategory (see wintraits_categorias_disponibles; e.g. "serums"). pais: country code (see wintraits_categorias_disponibles; e.g. "ES"). lang: "es" (default) or "en" (attribute names in English). Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027). | Not declared |
| wintraits_evaluar_concepto | Will this product work before I manufacture it? (¿Funcionará este producto antes de fabricarlo?) Evaluates a product before manufacturing it: Wintraits Match Index (similarity to winners, 0-100) from its attributes (assuming a complete listing), the changes that raise it most, the traps it has and the winning gaps it could fill. Args: precio_eur: planned selling price in euros. atributos: attribute -> value (a list for list-type attributes). Valid values in wintraits_opciones_concepto, e.g. {"ingredientes_clave": ["niacinamida"], "textura": "gel", "promesa_cuantificada": true}. volumen_ml: container volume in ml. descripcion: free description of the concept (optional). categoria: subcategory (see wintraits_categorias_disponibles; e.g. "serums"). pais: country code (see wintraits_categorias_disponibles; e.g. "ES"). lang: "es" (default) or "en" (attribute names in English). Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027). | Not declared |
| wintraits_evidencia | How much evidence is behind it? (¿Cuánta evidencia hay detrás?) Counters: validated findings, launches analysed and used for checking, replication rate, model accuracy versus the baseline, categories, countries and weight of each attribute family in the model. Args: lang: "es" (default) or "en". Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027). | Not declared |
| wintraits_hallazgos | What has been discovered and confirmed about winning products? Validated findings. (¿Qué se ha descubierto y comprobado sobre los productos que triunfan?) Each finding was discovered with some launches and then repeated in at least two 8-week periods with launches the system had not seen. Includes statement, lift with 95 % interval, products, period, attribute family, stability (1-3) and `cita`. On the free plan you see the 3 most stable per category; for the rest, the statement without figures (`bloqueados`). Agency plan: also those under observation, marked `preliminar`. Without a category: all of them. Args: categoria: subcategory (see wintraits_categorias_disponibles; empty = all). pais: country code (empty = all). lang: "es" (default) or "en" (attribute names in English; statements stay in Spanish for now). Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027). | Not declared |
| wintraits_indice_categoria | How many launches win in this category? How long does a new serum take to take off on Amazon Spain? (¿Cuántos lanzamientos triunfan en esta categoría? ¿Cuánto tarda en despegar un sérum nuevo?) Wintraits Success Ratio: of every 100, how many win and how many fail, median days to take off, overall and by quarter. Only groups with 30 launches or more. `cita` has the public URL and the date of the data to cite it. Args: categoria: subcategory (see wintraits_categorias_disponibles; e.g. "serums"). pais: country code (see wintraits_categorias_disponibles; e.g. "ES"). lang: "es" (default) or "en".

| wintraits_opciones_concepto | Valid attributes and values for `wintraits_evaluar_concepto` and for the optional `atributos` of `wintraits_diagnosticar_producto` in a category. `instrucciones_extraccion` says exactly how to read them from a listing. Args: categoria: subcategory (see wintraits_categorias_disponibles; e.g. "serums"). pais: country code (see wintraits_categorias_disponibles; e.g. "ES"). lang: "es" (default) or "en". The keys and values to send back are always the Spanish ids. Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027). | Not declared |
| wintraits_opinion | Was this report useful? Rate an answer that came with `id_informe` (diagnosis, comparison, quick check...). (¿Te ha servido? Valora un informe.) Ask the user and pass their answer; never rate on their behalf. Nothing from the listing is stored. Args: id_informe: the `id_informe` of the answer being rated. util: true if it was useful, false if not. comentario: optional comment from the user (up to 500 characters). lang: "es" (default) or "en". Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027). | Not declared |
| wintraits_panorama_categoria | Is this category worth launching in? At what price do products win? Which gap is still open? (¿Merece la pena lanzar en esta categoría? ¿A qué precio triunfan? ¿Qué hueco queda libre?) Category overview: what the ranking does not show. - `realidad`: of every 100 launches, how many win, how many fail and disappear, and how many days winners take to take off. - `precio`: share of winners by price band (and price per ml); `mejor` = checked winning band. - `huecos_ganadores`: winning combinations still used by few recent launches. - `trampas`: attributes with fewer winners than normal (lift < 1, checked with new products). - `tendencias`: attributes rising or falling among recent launches. - `paises` and `cambios_de_ficha`: comparison between countries and listing changes that precede rises. On the free plan the gaps and part of the traps and trends are counted in `bloqueado` without being shown. Args: categoria: subcategory (see wintraits_categorias_disponibles; e.g. "serums"). pais: country code (see wintraits_categorias_disponibles; e.g. "ES"). lang: "es" (default) or "en" (attribute names in English).

| wintraits_ranking | Which best sellers have the most complete listings? TOP 10 of the Wintraits Scan Index of a category. (¿Qué más vendidos tienen la ficha más completa? Ranking del Índice Wintraits Scan.) Among today's best sellers, the 10 with the highest Wintraits Scan Index (out of sample) and the index traits each listing has (`rasgos`), with the best sellers' middle half (`franja_mas_vendidos`). Brand, title and Amazon link only for listings with an index of 60 or more. Use it as examples of how the best sellers present the winning traits; the number is not comparable across categories and is not a sales probability. Args: categoria: Scan category id (see wintraits_buscar_categoria; e.g. "freidoras"). pais: country code (e.g. "ES"). lang: "es" (default) or "en". Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027). | Not declared |
| wintraits_scan_historia | How has this category changed? History of the Wintraits Scan Index of a Scan category. (¿Cómo ha cambiado esta categoría?) For each update: middle half (25-75 %) and median of the Wintraits Scan Index of best sellers and of the rest. If the best sellers' band rises, a listing needs to look more like them to be among them. Args: categoria: Scan category id (see wintraits_categorias_disponibles). pais: country code (e.g. "ES"). lang: "es" (default) or "en". Free and unlimited during the beta (until 2027-01-31).

Atributos ganadores, sin pegar ninguna ficha.) Full Scan profile: every trait that sets today's best sellers apart from the rest, with the share of each group that has it (`pct_mas_vendidos`, `pct_resto`), its `tipo` (producto = what the product is or offers, the part that also works outside Amazon; presentacion = how it is told online; tienda = depends on who sells), whether it counts in the Wintraits Scan Index, the medians of images, bullets, text length and price (`cifras`), the index bands and the link to its history. Use it to design or choose a product, brief a manufacturer, set price and format, or write a listing for Amazon, an own shop or another marketplace. To score a specific listing, use wintraits_chequeo_rapido. Exploratory snapshot, not validated with an exam: correlation, not causation. Args: categoria: Scan category id (see wintraits_categorias_disponibles, `solo_scan`; e.g. "hidratantes"). pais: country code (e.g. "ES", "FR", "DE", "IT"). lang: "es" (default) or "en".

| wintraits_seguir_ficha | Follow my Amazon listing every week. (Sigue mi ficha cada semana.) Only call it when the user explicitly asks to follow the listing: it is their consent. Requires a free key (Authorization: Bearer). Each Monday we check whether the listing changed and, when it does, the user sees in their account how its Wintraits Scan Index moved and how its sales rank did against similar listings that did not change (correlation, not causation). Only the ASIN is stored, never the listing text. Returns {"seguida": true, "desde": "YYYY-MM-DD"}. The user can unfollow it from their account. Args: asin: ASIN (10 characters) or Amazon product link. pais: country code when only the ASIN is given (default "ES"). lang: "es" (default) or "en". Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027). | Not declared |
