## 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 world-bank-country-indicator-ranking-3f333cc8
```

Example prompt: Can you rank the US, China, Germany, Japan, and Brazil by GDP and tell me which year each figure is from?

## When to prefer this

Use this endpoint when you need a direct ranked comparison of a small set of countries (2–6) on a single well-known World Bank indicator. It is ideal for quick benchmarking, investment screening, research summaries, or answering 'which country is best/worst at X?' questions. Prefer it over the historical trend endpoints when you need current snapshot rankings rather than time-series analysis, and over the country profile endpoint when you have multiple countries to compare simultaneously.

## Known failure modes

- Fewer than 2 or more than 6 countries supplied — request rejected
- Unrecognized country name or ISO code — listed in 'unknown' field with partial results
- Unsupported indicator value — request rejected or degraded response
- No World Bank data available for a country/indicator pair — that country appears in 'noData' list
- Stale or incomplete data — 'degraded' flag set to true with disclaimer

## How this service works

Rank up to 6 countries on one indicator (GDP, growth, inflation, unemployment...) with the year of each value.

## Output

A ranked array of up to 6 countries ordered by the requested indicator, each entry containing country name, ISO3 code, numeric value, data year, and rank position. Also includes a human-readable summary, indicator label, source URL, attribution to the World Bank, and an optional list of countries for which no data was available.
