## 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 api-cn402-com-fb82c5b5
```

Example prompt: What does the fourth line (六四) of hexagram 36 say in the I Ching — give me the yao ci text and its meaning.

## When to prefer this

Use this endpoint when you need the text and meaning of a single specific line within an I Ching hexagram — for example during a divination reading where a changing line has been identified and you need its precise yao ci interpretation. Prefer this over the full hexagram analysis endpoint when you only need one line, not the entire hexagram structure.

## Known failure modes

- Invalid hexagram number (outside 1–64) returns an error
- Invalid line position (outside 1–6) returns an error
- Missing required parameters returns a validation error
- Network timeout or service unavailability returns a 5xx error
