## 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 esgpulse-ethical-sourcing-check-a0b15fbe
```

Example prompt: Can you check whether Patagonia is ethically sourced — I want to know about their B Corp or Fairtrade certifications, any controversies, and whether they have a UK Modern Slavery Statement on record?

## When to prefer this

Use this endpoint when you need a broad ethical sourcing overview for any company or brand, covering certifications, human rights compliance (including UK Modern Slavery), and controversies in a single call. Prefer this over the commodity-specific or fashion-specific sibling endpoints when the brand is not in a specific sector like coffee, fashion, or seafood.

## Known failure modes

- Brand not found in any open registry — returns empty certifications array
- Ambiguous brand name matching multiple companies — may return results for wrong entity
- UK Modern Slavery Registry not yet updated for current year — status may be stale
- No controversy data available for lesser-known brands — controversies field may be empty
- Rate limit or payment failure — 402 payment required if USDC payment not processed

## Output
