Example prompt: What is the current French social levy rate (prélèvements sociaux) for LMNP rental income — give me the rate, unit, and legal sources used?

## When to prefer this

Choose this endpoint when you need a precise, legally-sourced French social levy rate broken down by income category, especially for patrimonial advisory (CGP) workflows, tax simulations, or LMNP/real estate scenarios. It is preferable over generic tax APIs because it references Légifrance and BOFiP directly, covers 19+ distinct French income types, and provides an explicit confidence rating per result.

## Known failure modes

- Invalid or unsupported type_revenu enum value returns an error with ok:false
- Missing required type_revenu field causes a validation error
- Rate not calculable for edge cases returns confiance: non_calculable
- Network or service downtime returns a 5xx error
- Outdated barème data if fiscal reference not yet updated for new tax year

## How this service works

Simulateur IFI, PER, IR et retraite (32 régimes). Logiciel CGP : bilan patrimonial, déclaration 2042, LMNP. Chiffres sourcés Légifrance et BOFiP. 14 jours d'essai.

## Output

A JSON object containing: a boolean success flag, the social levy rate value (typically a decimal percentage), the unit (e.g. RATE or PERCENT), a human-readable label, a confidence level (fiable/estime/partiel/sourcee/variable), an array of primary legal sources (e.g. LFSS articles, CSS articles), the fiscal year vintage, the capability name, and an optional usage warning indicating this is not personalised advice.
