## 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-0032ff5a
```

Example prompt: What does the Chinese almanac say about today — give me the full picture including the lunar date, gan-zhi pillars, zodiac, and which activities are auspicious (宜) or inauspicious (忌), plus any festival or solar term we're in.

## When to prefer this

Use this endpoint when you need a one-call, all-in-one Chinese calendar context for a specific date — covering lunar date, gan-zhi, zodiac, yi/ji activities, festivals, and solar terms together. Prefer over sibling endpoints (e.g. the festival-only or solar-term-only endpoints) when you need a comprehensive daily summary rather than a single piece of calendar data.

## Known failure modes

- Invalid date format — API returns error if date string is malformed
- Date out of supported range — very distant past or future dates may not be supported
- Network timeout or HTTP 402 payment required if USDC payment not attached
- Empty festival/solar-term fields when queried on a day with no active festival or term
