## 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 taxpulse-tax-treaty-withholding-rate-lookup-c71faf74
```

Example prompt: What is the withholding tax rate on dividends paid from the United States to a German tax resident under the US-Germany tax treaty, including any MLI modifications that apply?

## When to prefer this

Use this endpoint when you need precise, treaty-specific withholding tax rates and double-taxation relief rules for a specific country pair and income type, especially when MLI modifications matter. Prefer this over general tax rate comparison endpoints when the question involves cross-border transactions, treaty articles, or residency tiebreakers rather than domestic tax rates.

## Known failure modes

- No treaty exists between the specified country pair — returns null treaty result or 'no treaty' status
- Unsupported or unrecognized country code — returns validation error
- Ambiguous transaction type not matching supported income categories — may return generic treaty terms
- MLI position data unavailable for one or both countries — treaty returned without MLI overlay
- Rate limit or payment failure — HTTP 402 or 429 response
