A guide to the MPSTATS analytics API, a service for marketplace data from Wildberries, Ozon, and Yandex Market. It covers product, seller, brand, category, stock, sales, SKU, and review information.

Use it for product and niche research, competitor and seller analysis, brand monitoring, SKU analysis, and marketplace sales or stock reporting.

It provides ready-made commands and API references for marketplace research without requiring you to write the HTTP requests yourself.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00056	$0.02217
Opus 5	$0.00028	$0.01108
Sonnet 5	$0.00011	$0.00443
Haiku 4.5	$0.00006	$0.00222

Security

Grade B, and why

mpstats scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 27 executable files (scripts/account/account-limits.sh, scripts/common.sh, scripts/ozon/ozon-brand.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

Ready-to-use shell scripts in `scripts/`. Call via the Bash tool, do not rewrite HTTP. Full catalog with per-script use-cases and routing guidance: `scripts/README.md`. Run any script with `--help` for parameters.

How it starts

The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MPSTATS API

MPSTATS is a Russian marketplace analytics platform with data on Wildberries, Ozon, and Yandex Market: product research, category analysis, seller/brand monitoring, SKU-level sales, stock, and review data.

Work through the ready-made shell scripts in scripts/ — call them via the Bash tool instead of writing HTTP code. Reference files in references/ are API contracts only.

Token setup

Scripts auto-load the token from config/.env via scripts/common.sh. A per-command MPSTATS_TOKEN env var overrides the file.

Setup and where to get the token: config/README.md.

If the token is missing, offer the user exactly 2 options before continuing:

User sends the token in chat → agent creates config/.env itself.
User runs locally: cp config/.env.example config/.env and pastes the token into config/.env.

Token page: https://mpstats.io/userpanel (API token block). Requires an active MPSTATS subscription.

References

API contracts (endpoints, params, response semantics) — read on demand:

references/auth.md — base URL, auth headers, response codes, rate limits
references/pagination-filter-sort.md — common request/response model for all POST endpoints
references/wb-categories.md, references/wb-brands-sellers.md, references/wb-similar-sku.md — Wildberries
references/ozon-categories.md, references/ozon-brands-sellers-sku.md — Ozon
references/ym-categories.md — Yandex Market
references/account.md — API limits
references/coverage.md — what is wrapped by scripts vs. still uncovered
references/presentation.md — how to format analytical answers and brand-styled HTML/PDF reports

Result formatting

Lead with a concise conclusion, then evidence. Use compact tables for multi-entity results, charts for trends/segmentation/comparisons. Don't dump raw JSON unless asked — interpret what the numbers mean for the decision. For HTML/PDF reports follow the MPSTATS brand style in references/presentation.md.

Sanity check — flag anomalies, never report blindly

What ships with it

42 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
