## 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 publishing-calc-page-count-from-word-count-9de087c2
```

Example prompt: My manuscript is 72,000 words — how many printed pages will that be using 250 words per page, and I need 8 extra pages for front matter like title page and copyright?

## When to prefer this

Use this endpoint when you need a precise, print-ready page count calculation from a raw word count, especially when you need the even-page count for print production or want to account for front/back matter pages. Prefer this over manual estimation when preparing for spine width calculation, cover design, or printing quotes.

## Known failure modes

- Missing required 'words' query parameter returns an error
- Non-numeric words value causes validation failure
- Very low word counts (e.g. 0 or negative) may return unexpected or zero-page results
- Extremely high word counts may produce results but are not validated against realistic book lengths

## How this service works

Pages from a word count at your words-per-page figure, rounded up, plus even page count and sheets for print.

## Output

Returns the total word count used, exact text page count (decimal), rounded-up text pages, front/back pages added, total pages (text + front/back), even page count (rounded up to nearest even number for print), number of physical leaves/sheets, the words-per-page figure applied, a plain-English summary, and optional disclaimer or degraded/reasons flags.
