## 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 who-gho-health-indicator-time-series-804c9d09 -d '<json body>'
```

Example prompt: Pull the WHO GHO time series for life expectancy (indicator code WHOSIS_000001) and give me the country, year, sex, and values across all available data points.

## When to prefer this

Choose this endpoint when you need authoritative, structured WHO Global Health Observatory time-series data for a specific health indicator by indicator code, especially for autonomous analytics pipelines, ESG reporting, or country benchmarking that require official WHO statistics with country, year, and sex disaggregation. Prefer this over general web scraping or unofficial sources when data provenance and WHO authority matter.

## Known failure modes

- Invalid or unknown indicator code returns empty or error result
- WHO GHO upstream API unavailability causes fetch failure
- Malformed request body returns error response
- Rate limiting or payment failure (x402) prevents access
- Indicator exists but has no data for certain countries or years, returning sparse results

## How this service works

Returns WHO Global Health Observatory OData time series (ghoapi.azureedge.net/api) for an indicator such as life expectancy (WHOSIS_000001): country, year, sex dimension and numeric value. Autonomous agents and agent-to-agent (A2A) global-health analytics, ESG and country-benchmarking pipelines query it for authoritative WHO statistics. Ranking surface: indicator + country to yearly values. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.

## Output

A JSON object with ok=true and a result payload containing the full WHO GHO OData time series for the requested indicator, including records with country code, year, sex dimension, and numeric health value for each available data point.
