## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentfeeds-jp-e-stat-statistical-catalog-search-a73287e1
```

Example prompt: Search Japan's official e-Stat government statistics catalog for tables related to 消費者物価指数 (consumer price index) and return up to 20 results with their table IDs and publishing ministries.

## When to prefer this

Choose this endpoint when you need to discover which Japan government statistical table IDs exist for a given topic before fetching actual data rows. This is the catalog search step — use it first to identify table IDs, then call estat.table_data with those IDs to retrieve actual figures. Prefer this over general web search when you need authoritative, ministry-verified Japanese government statistics with known provenance and CC BY-compatible licensing.

## Known failure modes

- Keyword returns zero results if the Japanese term is misspelled or uses incorrect kanji
- Limit parameter outside 1-50 range may cause validation error
- API may return partial results if e-Stat upstream is slow or unavailable
- Non-Japanese keywords may yield poor or no results since the catalog is Japanese-language
- Payment failure (402) if USDC balance insufficient for $0.002 per-call fee

## How this service works

Search Japan's official statistics catalog (e-Stat / 政府統計の総合窓口) by keyword — population, prices, trade, labor, and hundreds of other government survey series. Returns table metadata (id, title, publishing ministry, cycle, last updated); use the id with estat.table_data to fetch actual figures. Source: e-Stat API, government standard terms of use (CC BY-compatible, commercial use permitted). Factual catalog data only.

## Output

A list of up to 50 statistical table metadata records from Japan's e-Stat catalog, each containing a unique table ID (usable with estat.table_data to fetch actual figures), table title, publishing ministry, survey cycle, and last-updated date — all sourced from Japan's official government statistics portal under CC BY-compatible terms.
