## 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-esg-score-intelligence-8ef1e19f
```

Example prompt: Can you explain why Tesla's MSCI ESG score and its Sustainalytics score are so different, and what methodology each agency uses to arrive at their ratings?

## When to prefer this

Use this endpoint when you need to understand ESG rating methodology differences across MSCI, Sustainalytics, ISS, and Bloomberg, or want to explain divergence in scores for a specific company. Prefer this over generic ESG data endpoints when the user's question is about how scores are calculated or why agencies disagree, rather than raw score lookup.

## Known failure modes

- Unknown or unsupported company ticker returns no data
- Rating agency not supported returns an error or empty response
- Ambiguous company name without ticker may return incorrect match
- Stale methodology data if agency updates scoring model without API refresh
- HTTP 402 payment required if USDC payment is not attached to request

## Output
