## 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 synthora-who-gho-indicator-time-series-48cac55e -d '<json body>'
```

Example prompt: Pull the WHO GHO time-series for indicator code WHOSIS_000001 — I need the full historical trend data on neonatal mortality rates for my health analytics model.

## When to prefer this

Use this endpoint when you need structured, authoritative WHO Global Health Observatory time-series data — especially for mortality, disease burden, or health coverage indicators — within an agent pipeline that supports x402 micropayments on Base. Prefer this over scraping WHO websites or using generic data APIs when you need clean, machine-readable historical health indicator data with payment-gated access and a verifiable receipt.

## Known failure modes

- Invalid or unrecognized WHO indicator code returns an empty or error result
- Missing indicatorCode parameter causes request failure
- WHO GHO data unavailable for the requested indicator returns empty result set
- Network or upstream WHO GHO service timeout
- Insufficient USDC balance or x402 payment failure blocks the call
