Example prompt: Pull the last 24 months of Japan's Cabinet Office leading composite index (CI) data so I can see recent economic cycle trends.

## When to prefer this

Choose this endpoint when you need official Japan Cabinet Office CI composite index data (leading, coincident, or lagging) in a structured, agent-friendly format with clear commercial-use terms, rather than scraping ESRI's own subdomain or manually querying e-Stat. It is ideal for macroeconomic dashboards, business cycle analysis, and integrating Japan economic cycle data into automated agent workflows. Prefer it over the estat.search or estat.table_data siblings when you specifically need the CI composite index without needing to search the broader statistics catalog.

## Known failure modes

- Invalid series enum value returns a validation error
- limit outside the 1-200 range returns an error
- e-Stat upstream API unavailability causes 502/503
- requesting data before 1980 returns empty or partial results
- missing required method/type fields in input schema returns 400

## How this service works

Cabinet Office Composite Index (CI), one of leading/coincident/lagging, 2020=100, monthly since 1980. Same e-Stat API family as estat.search/estat.table_data (routed there rather than the Cabinet Office's own ESRI subdomain, whose commercial-use terms were less clearly stated). Factual published data only; not investment advice or a forecast.

## Output

Returns a time series of monthly Cabinet Office Composite Index (CI) values, each with the reference month, index level (2020=100), and series type (leading, coincident, or lagging). Up to 200 monthly observations can be returned per call, defaulting to the 12 most recent months.
