## 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-ordinal-format-485be191
```

Example prompt: What is the ordinal figure and word form for 42 in Spanish, using the feminine gender?

## When to prefer this

Choose this endpoint when you need both the ordinal suffix/figure (e.g. '1st', '1er', '1.º') AND the spelled-out ordinal word form for a number, especially in a multilingual context supporting English, Spanish, French, or German. Prefer it over a generic number-to-words library when you need gender-aware ordinals (Spanish/French) or locale-specific formatting conventions (French 1er/2e, German 1.) in a single call.

## Known failure modes

- Non-integer or out-of-range value (above 999,999,999,999,999) returns an error or null result
- Unsupported language code returns an error or falls back to English default
- Supplying gender for English or German (where it is not applicable) may be ignored silently
- Missing required 'value' query parameter causes a validation error
- Decimal numbers or negative numbers may not be supported and return null or an error

## How this service works

Ordinal suffix and word for a number: 1st/2nd/3rd/11th, French 1er/2e, Spanish 1.º/1.ª, German 1. with the word form.

## Output

Returns a JSON object containing the ordinal figure (e.g. '42nd', '42.º'), the ordinal word (e.g. 'forty-second', 'cuadragésimo segunda'), the language used, and optional metadata fields such as summary and disclaimer. Null fields are included for unused output slots.
