## 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 1gateway-bank-of-korea-ecos-statistics-api-0fb41863
```

Example prompt: Can you pull the Bank of Korea base rate data from ECOS table 722Y001 monthly from January 2024 to December 2024, item 0101000?

## When to prefer this

Use this endpoint when you need official, BOK-authored macro time-series data from South Korea's ECOS database — specifically when you need English-labeled, normalized JSON output without having to interface with the raw ECOS API directly. Prefer this over general web scraping or third-party aggregators when data provenance and official sourcing matter. Best for base rate, money supply, trade, or any BOK-published statistical table.

## Known failure modes

- Non-BOK ECOS table code returns 403 (not charged)
- Invalid stat code format returns validation error
- Invalid cycle/period combination returns error
- Period format mismatch (e.g. monthly format with annual cycle) causes query failure
- Result truncated at 1,000 rows if date range is too wide
- Missing required parameters (stat, cycle, start, end) returns 400

## How this service works

Use when you need official Bank of Korea statistics (base rate, money supply, key indicators) as a time series. Input: stat (ECOS table code, e.g. 722Y001), cycle (A/S/Q/M/SM/D), start, end (period format of cycle), optional item (e.g. 0101000). Output: JSON series with English labels, units, observations [{period,value}] (max 1,000 rows) and source attribution. Only BOK-authored tables are served. Example: ?stat=722Y001&cycle=M&start=202401&end=202412&item=0101000

## Output

Returns a JSON object containing the ECOS stat code, Korean and English stat names, cycle type, a series array with item codes, English/Korean names, units, and an observations array of {period, value, periodRaw} objects (up to 1,000 rows), plus truncation flag, source attribution, license, and cache metadata.
