## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

### ✨ Why this over single-marketplace seller scrapers

- **Multi-marketplace** - Wildberries, Ozon and Yandex Market (RU) plus Kaspi.kz (KZ) in one run,
  unified seller schema.
- **Legal dossier** - the actor resolves each seller's registered entity: `ИП …` / `ООО …`, **OGRN /
  OGRNIP**, and, where the platform discloses it, **INN**, KPP, trademark and legal address. That turns
  a store name into a contactable B2B lead.
- **Monitor mode** - schedule it and get alerted (webhook → n8n/Telegram/Slack) when a **new competitor**
  appears in your niche.

### ⚙️ Input

| Field | Description |
|---|---|
| `mode` | `search` (collect sellers now) or `monitor` (diff vs last run, flag new/gone). |
| `searchQueries` | Keywords; each is expanded into the sellers who rank for it. |
| `platforms` | `wildberries`, `ozon`, `yandexmarket` and/or `kaspi`. |
| `maxPagesPerQuery` | How many result pages to scan per query, per platform. |
| `maxSellersPerPlatform` | Cap on unique sellers kept (sorted by reach in results). |
| `fetchDossier` | Fetch legal entity / registration numbers per seller (one extra request each). |
| `cities`, `kaspiOfferDepth` | Kaspi: cities to query and how many products to expand into merchant offers. |
| `alertOnly`, `notifyWebhookUrl` | Monitor mode: emit only new/gone sellers and POST a summary webhook. |
| `proxyConfiguration` | Apify Proxy (residential RU) - required for Ozon/Yandex Market, optional for WB/Kaspi. |

### 📤 Output (one row per seller)

`platform, sellerId, name, legalName, legalFullName, legalAddress, inn, ogrn, kpp, trademark, storeUrl,
productCount, avgRating, totalReviews, categories[], foundByQuery[], scrapedAt` (+ `changeType`,
`firstSeenAt` in monitor mode).

Sellers with neither a store name nor registration data are skipped, not emitted as blank rows.

### 🗺️ Coverage by platform

Which dossier fields each marketplace makes available per seller:

- **Wildberries** - store name, legal entity, INN, OGRN/OGRNIP, KPP, trademark and legal full name.
- **Ozon** - store name, legal entity, legal address and OGRN/OGRNIP. INN is not disclosed by the platform.
- **Yandex Market** - store name, legal entity, INN, OGRN/OGRNIP and legal address. Some cross-border
  stores disclose a legal name and address but no Russian INN/OGRN.
- **Kaspi.kz** - store name, rating and review count. Legal entity details are not disclosed by the platform.

### 📝 Notes

- `productCount` = the seller's cards **matched by your queries in this run** (reach in results), not
  their full catalogue.
- **Proxy** - Required on Apify: set `proxyConfiguration` to Apify Residential proxy with country RU.
  All sources require a Russian IP. The `proxyConfiguration` field also accepts custom proxy URLs if you
  prefer to bring your own residential RU proxy.

### ▶️ Quick start

**Search mode** - sellers ranking for a niche, with legal dossier:

```json
{
  "mode": "search",
  "searchQueries": ["наушники", "детская одежда"],
  "platforms": ["wildberries", "ozon", "yandexmarket", "kaspi"],
  "maxPagesPerQuery": 5,
  "maxSellersPerPlatform": 30,
  "fetchDossier": true,
  "cities": ["750000000"]
}
```

**Monitor mode** - alert when a new competitor shows up in your niche:

```json
{
  "mode": "monitor",
  "searchQueries": ["наушники"],
  "platforms": ["wildberries"],
  "alertOnly": true,
  "notifyWebhookUrl": "https://example.com/hooks/new-seller-alerts"
}
```

Set a schedule under **Schedules** in the Apify Console to run `monitor` mode periodically. State
carries over between runs via the Key-Value Store.

### 💰 Pricing

Pay-per-event: you are charged for each seller row returned, plus Apify platform usage. The current
per-lead price is shown in the **Pricing** section of this page. Turn `fetchDossier` off for a faster,
name-only run with lower platform usage when you don't need the legal entity yet (the per-lead price is
the same either way).

### 🇷🇺 RU / На русском

**B2B lead-gen: находит продавцов Wildberries, Ozon, Яндекс.Маркета и Kaspi.kz по нише и обогащает
досье юрлица (ИНН, ОГРН, наименование, адрес) через официальные данные площадок. На выходе не список
ников, а сделко-пригодный лид с реквизитами.**

- **Поиск продавцов по запросу** - «наушники», «детская одежда», «кофе» и т.п. раскрываются в список
  продавцов, которые ранжируются по этому запросу, с дедупликацией.
- **Досье с реквизитами** - актор резолвит юрлицо продавца (ИП/ООО), ОГРН/ОГРНИП и, где площадка это
  публикует, ИНН, адрес, КПП и товарный знак - превращая название магазина в контактный B2B-лид. ИНН
  надёжно доступен у Wildberries и Яндекс.Маркета; Ozon публикует юрлицо/адрес/ОГРН, но не ИНН ни у
  одного продавца; у Kaspi реквизиты юрлица не публикуются в принципе.
- **Monitor** - вебхук-алерт, когда в нише появляется новый конкурент.
- Целевая аудитория: SaaS для селлеров, фулфилмент-компании, финтех, агентства, дистрибьюторы -
  все, кому нужен не мониторинг цен, а квалифицированный список продавцов для аутрича.

Тариф - оплата за событие: списывается за каждую строку продавца на выходе, плюс platform usage
Apify; актуальная цена за лид указана в блоке **Pricing** на этой странице. `productCount` - это охват
продавца в результатах ваших запросов за этот прогон, а не весь его каталог.

# Actor input Schema

## `mode` (type: `string`):

search = collect sellers now. monitor = compare sellers vs the previous run (needs a schedule) and flag new competitors, with optional webhook alerts.

## `searchQueries` (type: `array`):

Keywords to search, e.g. 'наушники', 'детская одежда', 'кофе'. Each query is expanded into sellers who rank for it.

## `platforms` (type: `array`):

Which marketplaces to scan. wildberries and yandexmarket return INN when the seller discloses it; ozon returns legal name and OGRN; kaspi rating only.

## `maxPagesPerQuery` (type: `integer`):

How many result pages to scan per query (Ozon collects its sellers from page 1 only). Higher = more sellers discovered, more cost.

## `maxSellersPerPlatform` (type: `integer`):

Hard cap on unique sellers kept per platform (sorted by reach in results). Dossier is fetched only for kept sellers.

## `fetchDossier` (type: `boolean`):

Fetch legal entity and registration numbers per seller (one extra request per seller; on Yandex Market it also fills in the store name). Turn off for a faster, name-only run.

## `cities` (type: `array`):

Kaspi city IDs (merchants/offers vary by city). 750000000 Almaty, 710000000 Astana, 591010000 Shymkent. WB ignores this.

## `kaspiOfferDepth` (type: `integer`):

Kaspi only: how many top products per query/city to expand into merchant offers (cost control). More = more merchants found.

## `alertOnly` (type: `boolean`):

Monitor mode only: emit just new/gone sellers instead of the full set.

## `notifyWebhookUrl` (type: `string`):

Monitor mode: POST the run summary (counts, per-platform, degraded, changes) to this URL - wire it to n8n/Zapier/Make for Telegram/Slack alerts on new competitors.

## `proxyConfiguration` (type: `object`):

Required on Apify: set proxyConfiguration to Apify Residential proxy with country RU. All sources require a Russian IP.
