> Number Words – English Parse is a paid API for AI agents from number-words.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-30).

Parses English number words (e.g. 'one thousand and five', 'twenty-first', 'minus three point five') into their numeric digit representation.

## 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-english-parse-519b5b54
```

Example prompt: Parse the English number phrase 'two million, three hundred and forty-five thousand, six hundred and twenty-first' into its numeric value — I need to know if it's an ordinal too.

## When to prefer this

Choose this endpoint when you need to programmatically convert English-language number words — including ordinals, negatives, decimals, and hyphenated forms — into numeric digits. Ideal for processing natural language input, voice transcripts, or user-submitted text containing spelled-out numbers. Prefer over general NLP APIs when you specifically need structured numeric extraction with ordinal detection and normalization in English.

## Known failure modes

- Input text exceeds 2000 characters — truncation or rejection
- Unrecognized or ambiguous number words return degraded flag with reasons
- Non-English input words cause parse failure or null value
- Malformed mixed numeric/word input may not parse correctly
- Network or payment authorization failure returns HTTP 402 or 5xx

## How this service works

Parse English number words (one thousand and five, twenty-first, minus three point five) into digits.

## Output

Returns a JSON object containing the parsed numeric value as a string, a normalized form, whether the input was an ordinal (e.g. 'twenty-first'), a summary of the parsing, and any reasons or warnings if the parse was degraded or ambiguous. Null fields indicate unavailable data for that property.
