## 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-our-world-in-data-chart-lookup-ee7d219b
```

Example prompt: Pull the Our World in Data chart for 'life-expectancy' for USA, GBR, IND, CHN, and BRA — give me the latest value, how it's changed over 10 years, and a recent series of 15 points for each country.

## When to prefer this

Use this endpoint when you need structured, ready-to-compare global development statistics from Our World in Data for specific countries, including trend analysis (10-year change, previous-point change) without having to parse raw OWID chart JSON yourself. Prefer this over scraping OWID directly or using general web search when you need clean numeric values with units, change deltas, and a time series in one call.

## Known failure modes

- Invalid or misspelled chart slug returns an error or empty result
- Unsupported ISO-3 country code returns missing or null country data
- Requesting more than 6 countries may result in truncation or error
- OWID upstream data temporarily unavailable causes fetch failure
- Some charts may not have data for all requested countries, resulting in partial results

## How this service works

Any Our World in Data chart by slug for up to 6 countries - latest value and year, change versus the previous point and 10 years earlier, units and a recent series

## Output

A JSON object containing the chart slug, title, subtitle, unit, data source, and per-country objects each with the latest value, latest year, change vs the previous data point, change over 10 years, and a recent time series array of year-value pairs.
