## 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 qotien-cdhr-french-high-income-differential-contribution-calculator-b0d9d52e -d '<json body>'
```

Example prompt: Can you calculate the CDHR I'd owe as a married couple filing jointly with a revenu fiscal de référence of 600 000 €, 2.5 parts de quotient familial, 1 personne à charge, and 80 000 € of PFU dividend income?

## When to prefer this

Use this endpoint when you need a precise, legally-sourced calculation of the French CDHR (Contribution Différentielle sur les Hauts Revenus, CGI art. 224) for a household, especially when handling complex cases involving PFU financial income corrections, multiple dependents, or adjusted RFR. Prefer this over generic tax estimators when you need confidence levels and primary legal source citations (Légifrance/BOFiP) for compliance or CGP reporting purposes.

## Known failure modes

- Missing required field revenu_fiscal_reference returns validation error
- RFR below CDHR threshold (250k single / 500k couple) returns value of 0 without error
- Invalid situation familiale enum value returns schema error
- Negative income values rejected by minimum:0 constraint
- Network timeout or payment failure returns non-200 with payment required error

## Output

Returns a JSON object with 'ok' status, the CDHR amount in EUR with label and unit, a confidence level (fiable/estime/partiel/sourcee/variable), the legal sources used (e.g. CGI art. 224), the fiscal millesime (year of tax scales applied), the domain ('fiscal'), and an optional warning that the result is informational and not personalized tax advice.
