## 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-simulateur-retraite-progressive-fraction-de-pension-77a89416 -d '<json body>'
```

Example prompt: Can you simulate the retraite progressive for a salarié born on 1963-06-15, with an effective date of 2025-11-01, 158 quarters acquired, working at 60% (quotité 0.60), and a gross annual pension of 18 000 euros?

## When to prefer this

Choose this endpoint when you need a legally-sourced, CGP-grade simulation of French progressive retirement (retraite progressive) pension fractions, specifically the partial pension drawn while still working part-time. It covers salariés, fonctionnaires, and TNS/professions libérales across multiple régimes, and cites Légifrance and BOFiP sources. Prefer it over generic retirement calculators when you need French regulatory accuracy, confidence scoring, and legal traceability for client advisory (CGP) use cases.

## Known failure modes

- Age below minimum threshold (55, or 60 after 01/09/2025) returns validation error
- Trimestres below 150 returns non_calculable or error
- quotité_travail outside allowed range for statut (e.g. salarié below 0.40 or above 0.80) returns error
- Invalid date format (non YYYY-MM-DD) triggers schema validation failure
- Missing required fields (age or trimestres or date_effet) returns ok:false with error field
- TNS diminution_revenus outside 0.20–0.60 range returns error
- Conflicting quotite_travail and diminution_revenus for non-TNS statut may return partial result
