## 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-to-words-converter-fc08ef67
```

Example prompt: Can you spell out 1,200,089.45 in English words, including the currency form showing dollars and cents?

## When to prefer this

Choose this endpoint when you need reliable English word representation of numbers for legal documents, checks, accessibility output, or any context requiring spelled-out numeric values — especially when you need currency-style (dollars and cents), ordinal, or negative number forms. Prefer this over manual formatting or LLM generation when precision and consistency across large numbers (up to quadrillions) are required.

## Known failure modes

- Missing or malformed 'input' query parameter returns an error
- Number exceeds supported range (beyond quadrillions) may return an error or unexpected output
- Non-numeric input strings will likely cause a parsing error
- Decimal inputs with more precision than supported may be truncated or rejected

## How this service works

Number to English words: integers up to quadrillions, decimals ('point eight nine'), negative numbers, plus a currency-style form ('one million two hundred… dollars and 89 cents'), ordinal form and digit grouping. $0.01 per call.

## Output

A text string expressing the input number in English words. Depending on the requested form: a plain word string for integers and decimals (e.g. 'one thousand two hundred'), a currency phrase (e.g. 'one thousand two hundred dollars and fifty cents'), an ordinal form (e.g. 'one thousand two hundredth'), or digit-grouped representation. Negative numbers are prefixed with 'negative' or 'minus'.
