## 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 signaldesk-ai-world-bank-indicator-lookup-52aaca41
```

Example prompt: Can you pull the last 5 years of GDP data for Portugal from the World Bank — the indicator is NY.GDP.MKTP.CD?

## When to prefer this

Use this endpoint when you need structured, time-series economic or development data sourced directly from the World Bank for a specific country and indicator. It is ideal when you have a known World Bank indicator code and need a small number of the most recent observations with provenance metadata. Prefer this over scraping or general web search when you need machine-readable, citable World Bank data with license information included.

## Known failure modes

- Invalid or unknown indicator code returns an empty observations array or error
- Non-existent ISO country code returns a 400 or empty result
- Limit parameter outside 1–20 range rejected by schema validation
- World Bank upstream API downtime causes request failure
- Data for requested year range may be sparse or missing for some indicators/countries

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object with a source block (provider, license, source URL, fetched_at, expires_at, transformed flag), the human-readable indicator name, and an array of annual observations each containing year, numeric value, and country name.
