## 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 depwatch-brief-dependency-update-digest-4c06c139
```

Example prompt: Give me an LLM-written digest of the most consequential dependency updates and breaking changes from the past 30 days, with upgrade recommendations.

## When to prefer this

Use this endpoint when you need a human-readable, opinionated narrative summary of dependency changes rather than raw changelog data. It is ideal for generating weekly/monthly briefings for engineering teams, automating dependency health reports, or when you want upgrade recommendations synthesized across many packages in a single call rather than querying each package individually.

## Known failure modes

- No changes found in the window — brief may be empty or indicate no significant updates
- Invalid 'since' datetime format returns a 400 error
- Payment not provided or insufficient USDC results in 402 Payment Required
- Service temporarily unavailable returns 503
- LLM generation failure may fall back to template-based brief (reflected in generatedBy field)

## How this service works

An LLM-written digest of the most consequential dependency updates and breaking changes in the window, with an upgrade recommendation.

## Output

A structured object containing a 'brief' field with a natural-language LLM-written narrative summarizing the most impactful dependency changes and upgrade recommendations for the time window, along with metadata indicating whether it was generated by an LLM or template, and the count of underlying changes analyzed.
