## 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 agent-data-tools-revmesh2074-workers-dev-population-by-country-total-6fda8024
```

Example prompt: What's the total population, annual growth rate, and urban share for Brazil over the last 5 years, according to World Bank data?

## When to prefer this

Choose this endpoint when you need reliable, citable World Bank population figures — total population, growth rate, or urbanization percentage — for any country, without setting up a World Bank API key. It answers instantly from a committed data snapshot, making it ideal for market sizing, per-capita calculations, and demographic research in automated workflows. Prefer this over scraping World Bank directly or using general web search when you need structured, machine-readable demographic data with a known provenance date.

## Known failure modes

- Invalid or unrecognized country code or name returns an error or empty result
- Years parameter outside 1-10 range may be rejected or clamped
- World Bank snapshot may lag 1-2 years behind real-time data for the most recent year
- Small territories or disputed regions may not have complete data
- Network failure or worker downtime returns a 5xx error

## How this service works

Population of any country from World Bank data: total population, annual population growth in % and the urban share of the population in %, for the last 1-10 years with the newest year first. Country by ISO code (SE, SWE) or English name. Read from a committed World Bank Open Data snapshot (CC BY 4.0), so every call answers at once; the snapshot date is in the answer. Use for market sizing, per-capita figures and demographics.

## Output

Returns a JSON object with country metadata (ISO codes, region, capital, income level), and three time-series datasets — total population values, annual population growth percentages, and urban population share percentages — each covering up to 10 years newest-first, plus the World Bank snapshot date and indicator names.
