## 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 saylor-innovations-data-desk-world-bank-indicator-data-25ffde0a
```

Example prompt: Pull World Bank data for the GDP indicator NY.GDP.MKTP.CD for the US, China, Germany, Japan, and India over the last 15 years, and show me the latest values and how much each economy has grown over the period.

## When to prefer this

Use this endpoint when you need structured, multi-country World Bank economic or development data — including GDP, population, inflation, health, or education indicators — with automatic period-change calculations and indicator definitions included. Prefer it over raw World Bank API calls when you want a clean, pre-processed JSON response with latest values and percent changes already computed. It is particularly useful for comparative country analysis or when you need the indicator's human-readable definition alongside the data.

## Known failure modes

- Invalid or unknown indicator code returns empty or error response
- Country ISO code not recognized returns no data for that country
- Requesting more than 10 countries may be silently truncated
- Years outside the 1–60 range may be rejected or defaulted
- World Bank API upstream outage causes failed data retrieval
- Some indicators may have sparse or missing data for certain countries/years

## How this service works

World Bank Open Data for any indicator code and up to ten countries over recent years, with latest value, period change and the indicator definition.

## Output

A JSON object containing: the indicator's ID, name, and definition; the number of countries with data returned; and a series array with one entry per country, each including the country name, ISO3 code, yearly observations in ascending order, the most recent year's value, and the percent change from the first to the latest observation. A plain-language caveat note may also be included.
