# Seerfar Ozon Keyword Back-Search

This skill reverse-looks-up Ozon search keywords **by a list of product SKU IDs** in the Seerfar analytics database: pass up to 20 SKUs (your own listing or a competitor's) and it returns the search terms those products appear under — organic and/or ad — each enriched with a full market profile (search volume, 30-day growth, product/seller/competitor counts, average price, conversion concentration, top products, plus per-term organic/ad channel, natural rank, exposure, and conversion in the `dimension` object). It is the starting point for Ozon keyword reverse lookup, listing-title optimization, and competitor traffic-word discovery.

## Core Concepts

**SKU-driven, not keyword-driven**: unlike keyword mining (expand *from* a seed term) or market keyword search (browse the whole market), this endpoint takes `skuIds` and returns the search terms *those specific products* rank for. The direction is product → keywords (reverse).

**`hasVariant` is required**: every request must declare whether to exclude variants — `0` keep variants, `1` exclude variants. Pick `1` when you want de-duplicated keyword coverage for a parent listing.

**Natural vs ad terms**: `type` filters the search-term channel — `["0"]` organic (organic search terms) only, `["1"]` ad (ad search terms) only; omit to get both. Combine with the `naturalRank` / `adRank` range filters to qualify positioning.

**Back-search metrics live in `dimension`**: each returned term carries a `dimension` object with the reverse-lookup-specific metrics — `type` (`0` organic / `1` ad), `naturalRank` (the SKU's natural rank for that term), `exposure` (exposure share, 0–1), `conversion` (conversion rate, 0–1), and `x` (opaque position indicator). The input filters `type` / `naturalRank` / `adRank` / `exposure` / `conversion` filter on these same per-term values. Note: `relevancy` is defined in the schema but is **not** returned by this endpoint.

**Platform coverage**: each keyword record carries a `platform` field (`0` = Ozon, `1` = Wildberries). The dataset is Ozon-centric; Wildberries rows appear where available. There is no input to restrict the platform — filter client-side if needed.

**Match mode**: `matchType` controls how `includeKeywords` / `excludeKeywords` are matched — `0` exact, `1` fuzzy.

## Calling the Tool

- **API Endpoint**: `/seerfar/ozon/keywordBackSearch` (full parameters/responses/error codes in `references/api.md`)
- **Python Script**: `python scripts/ozon_keyword_back_search.py '<JSON params>' [--inline]`
- **Cost constraint**: This tool consumes credits. Within the same session and same parameter combination, it defaults to a single call with a 24-hour local cache. Do not automatically retry with different keywords, pagination, or parameters on failure/empty results. Inform the user of additional credit consumption before continuing retrieval.

**Output strategy (script default behavior)**:
- **Always** write the full response to `<cwd>/nexscope/<YYYY-MM-DD>/<session>/data/ecommerce-ozon-keyword-back-search-<timestamp>.json` (`<cwd>` is the working directory when the script executes, which in Claude Code is the current project directory; `<session>` is taken from the `SESSION_ID` environment variable, automatically grouped by user task; **do not write to /tmp**; error if the current directory is not writable)
- Response body <= 8 KB: write to disk then print full JSON to stdout
- Response body > 8 KB: write to disk then print only a summary to stdout (top-level fields, common counts like `total`/`costToken`, length of the largest list field + first 3 samples)
- Add `--inline` to force full output to stdout (still writes to disk)

**Reading data**: Check the summary first to determine if it is sufficient. When specific fields are needed, use `jq` or `ConvertFrom-Json` to extract from the saved JSON file as needed, avoiding loading the entire JSON into context.
## Authentication & Credits

If you encounter authentication or credit issues:

### Error conditions
- **API Key not configured**: The `NEXSCOPE_API_KEY` environment variable is not set.
- **HTTP 401 or 402 status code**
- **Insufficient credits/balance**: Response message indicates credit balance exhausted, quota exceeded, subscription expired, or recharge required.

### Resolution steps
1. Set the `NEXSCOPE_API_KEY` environment variable with a valid API key.
2. If credits are insufficient, visit https://www.nexscope.ai/pricing?co-from=skillNS to top up your balance.
3. For onboarding and setup guidance, refer to https://www.nexscope.ai/help/skills-external-access?co-from=skillNS
## Usage Examples

**1. Reverse-lookup a single SKU's traffic keywords (sort by search volume)**
```json
{"skuIds": [4380710124], "hasVariant": 0, "page": {"page": 1, "pageSize": 10, "orders": [{"field": "searchVolume", "direction": "DESC"}]}}
```

**2. Organic terms where the SKU ranks near the top**
```json
{"skuIds": [4380710124], "hasVariant": 1, "type": ["0"], "naturalRank": {"max": 10}, "page": {"page": 1, "pageSize": 20, "orders": [{"field": "searchVolume", "direction": "DESC"}]}}
```

**3. Ad search words only, with an ad-rank floor**
```json
{"skuIds": [4380710124], "hasVariant": 0, "type": ["1"], "adRank": {"max": 50}, "page": {"page": 1, "pageSize": 20, "orders": [{"field": "searchVolume", "direction": "DESC"}]}}
```

**4. Narrow with include / exclude lists**
```json
{"skuIds": [4380710124], "hasVariant": 0, "page": {"page": 1, "pageSize": 20}, "includeKeywords": ["платье"], "excludeKeywords": ["ремень"], "matchType": 1}
```

## How to Build Queries

1. **Always lead with `skuIds` + `hasVariant`**: both are required and define the reverse-lookup target. Use real Ozon SKU IDs (the same IDs returned by Seerfar Ozon product / shop / category skills).
2. **Lead with `page.orders`**: sort by the metric you care about (`searchVolume` DESC for traffic weight, `sellers` ASC for low competition, `count30GrowthRate` DESC for rising terms).
3. **Split organic vs ad with `type`**: pass `["0"]` or `["1"]` to focus a listing-optimization pass (organic) or an ads pass (ad), then bound `naturalRank` / `adRank` to qualify positioning — these filter on the values surfaced in each row's `dimension`.
4. **Use `includeKeywords` / `excludeKeywords` to steer**: force in must-have modifiers and strip noise without running a second query.

## Display Rules

1. **Present data only**: show reverse-looked-up keyword metrics in a clear table without subjective advice.
2. **Lead with keyword columns**: `query` / `queryCn` (Chinese translation), then `searchVolume`, `count30GrowthRate`, `productCount`, `sellers`, `avgPrice`; show `dimension.naturalRank` and `dimension.type` (organic/ad) to convey how the SKU ranks for each term.
3. **Russian keywords**: preserve the original `query`; the `queryCn` field provides a Chinese translation when available.
4. **Channel tag**: when `type` is omitted and both organic and ad rows are present, show `dimension.type` (`0` organic / `1` ad) and `dimension.naturalRank` so the user can distinguish them.
5. **Large result sets**: when `total` is large, show the top rows and remind the user they can persist the full response via the large-response pattern below, or page further with `page.page`.
6. **Error handling**: when `code` is not `200` (or `errcode` is not `200`), explain the reason from `msg` / `errmsg` and suggest adjusting the SKU list or filters.

## Important Limitations

- **`skuIds` + `hasVariant` + `page` required**: a payload missing any of these is rejected.
- **`skuIds` capped at 20**: pass more than 20 and the request is rejected or truncated.
- **No keyword seed**: this endpoint has no `keyword` parameter — it is reverse (SKU → keywords), not expansion (keyword → keywords). Use the keyword mining skill to expand from a seed.
- **No `searchDate` / `categories` input**: only `historyDate` (historical month) is accepted; there is no category filter. Use the market keyword search skill for month- or category-scoped browsing.
- **Nested fields**: `products[*]` (Top Products) and `dimension` (per-term back-search metrics: `type`, `naturalRank`, `exposure`, `conversion`, `x`) are structured and decision-useful — see `references/api.md` for sub-fields. `categoryInfos` is defined in the schema/columns but is **not** returned in `data[*]` on this endpoint (same as the keyword-mining sibling; the market-keyword-search sibling does return it — don't assume parity). `relevancy` is likewise defined in the schema but **not** returned.

## User Expression & Scenario Quick Reference

**Applicable** — SKU-driven Ozon keyword reverse lookup:

| User Says | Scenario |
|-----------|----------|
| "Reverse-lookup keywords for this Ozon product / SKU" | Reverse keyword lookup for a SKU |
| "Which search terms drive traffic to this Ozon listing" | Traffic-word discovery for a listing |
| "Ozon competitor SKU ranking/traffic keywords" | Competitor traffic-word mining |
| "Ozon product organic vs ad keywords" | Organic vs ad term breakdown |
| "Ozon keyword reverse lookup by SKU" | Generic reverse keyword lookup |

**Not applicable** — Needs beyond SKU-driven reverse lookup:
- Browse/rank the whole market's hot keywords (no SKU) → use the Seerfar Ozon market keyword search skill.
- Expand outward from a seed keyword → use the Seerfar Ozon keyword mining skill.
- A specific SKU's price/sales/stock → use a product-level Seerfar Ozon data source.
- A specific seller's catalog → use the Seerfar Ozon shop search skill.
- Category-tree browsing → use the Seerfar Ozon category search skill.

**Boundary judgment**: if the user has a **product/SKU** (own or competitor) and wants the **search terms it ranks for**, start here. If they want to **browse the market** (no SKU) or **expand from a seed keyword**, route to the market keyword search or keyword mining skill respectively.
