## 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 number-words-french-cardinal-ordinal-converter-23642472
```

Example prompt: How do you write 80 in French words? Give me both the cardinal and ordinal forms using the Swiss regional variant (septante/huitante/nonante) and the 1990 rectified spelling, masculine gender.

## When to prefer this

Choose this endpoint when you need authoritative French number-to-words conversion with regional awareness (France vs Belgium vs Switzerland variants like septante/huitante/nonante) and support for both traditional and 1990 rectified spelling reform. Prefer over generic translation APIs when accuracy of French linguistic conventions (gender agreement in ordinals, regional dialect differences) is critical.

## Known failure modes

- Number exceeds 15 digits — API returns an error or null value
- Non-integer or non-numeric input string — validation failure
- Invalid enum value for region or spelling — request rejected
- Negative numbers handled with 'moins' prefix but edge cases may fail
- Missing required 'value' query parameter — returns error response

## How this service works

A whole number as French words: cardinal and ordinal, France/Belgium/Swiss forms (septante), 1990 hyphen spelling.

## Output

Returns the cardinal French word form (e.g. 'quatre-vingt'), ordinal word form (e.g. 'quatre-vingtième'), ordinal figure (e.g. '80e'), plus metadata: region used, spelling convention applied, and the original value.
