## 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`):

## When to prefer this

Use this endpoint when you need a quick, low-cost programmatic calculation of text size metrics — particularly useful for UI layout validation, content length checks, or pre-processing text before storage or transmission. Prefer this over manual counting when automation or scale is needed.

## Known failure modes

- Missing or empty 'text' field returns an error or empty result
- Extremely long strings may time out or be truncated
- Malformed JSON input body returns a 400-level error
