## 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 world-bank-indicator-topic-taxonomy-a3f402d2 -d '<json body>'
```

Example prompt: Can you pull up the full list of World Bank indicator topics — like Economy & Growth and Financial Sector — with their IDs and descriptions so I can pick the right category for my data query?

## When to prefer this

Use this endpoint when you need a structured taxonomy of World Bank indicator topics to navigate or enumerate available data categories, particularly before querying specific World Bank indicators by topic ID. Prefer this over scraping the World Bank website or using the full indicators list when you only need the top-level subject taxonomy.

## Known failure modes

- Network timeout or service unavailability returning a 5xx error
- Payment required error (402) if x402 payment header is missing or insufficient
- Empty or malformed JSON response if upstream World Bank API is down
- Rate limiting if called too frequently
