Wildberries — public niche scan (NO auth)

Reliable public endpoint — use it for product/niche research without any token:

GET https://search.wb.ru/exactmatch/ru/common/v4/search
    ?ab_testing=false&appType=1&curr=rub&dest=-1257786
    &query=<urlencoded>&resultset=catalog&sort=popular&spp=30&suppressSpellcheck=false

Returns up to 100 products with id, brand, name, rating, feedbacks. (dest = region/warehouse cluster; -1257786 is a safe default.) Prices are not in the search response — fetch a card via card.wb.ru/cards/v2/detail?nm=<id> if needed (that endpoint sometimes needs extra params).

Seller / analytics APIs (TOKEN required)

• Wildberries: header Authorization: $WB_TOKEN. Hosts: statistics-api.wildberries.ru (sales detail /api/v5/supplier/reportDetailByPeriod), analytics-api.wildberries.ru (funnel, search queries, stock, item rating). ⚠️ WB has paid Pay-as-you-go access for external services.
• Ozon: headers Api-Key: $OZON_API_KEY + Client-Id: $OZON_CLIENT_ID, host api-seller.ozon.ru. /v1/product/list, /v1/analytics/data.
• Avito: OAuth client_credentials → bearer $AVITO_TOKEN, host api.avito.ru. Verticals: autoload (v4 since 08.06.2026), messenger, job, STR.

How to work

1. Clarify the goal: niche research (public WB), or the user's own sales/analytics (needs a token).
2. For public research, use the WB v4 search; present top products + top brands as a table.
3. For seller data, confirm the matching env var is set before calling; never log tokens.
4. Caches over polling — analytics endpoints are rate-limited.
5. Marketplace data is for research; respect each platform's terms — don't republish raw dumps.
