## 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 hex-elixir-erlang-package-updates-digest-00e5a506
```

Example prompt: Can you give me a digest of the most important Hex package updates and breaking changes since January 1st 2025, with upgrade guidance?

## When to prefer this

Use this endpoint when you need a curated, human-readable summary of Hex ecosystem changes rather than raw package metadata. Ideal for developer teams wanting a weekly/monthly briefing on Elixir/Erlang dependencies, or when you need upgrade guidance without manually scanning Hex.pm changelogs. Prefer this over raw Hex.pm API queries when narrative context and prioritization matter.

## Known failure modes

- No changes found in the specified window — returns a brief indicating no significant updates
- Invalid date-time format for 'since' parameter — returns a 400-level error
- Upstream Hex data source unavailable — may return 5xx or empty digest
- Payment not completed — returns 402 Payment Required before content is served

## How this service works

Plain-English digest of the Elixir/Erlang Hex ecosystem: which tracked packages (phoenix, ecto, plug, phoenix_live_view, and more) shipped notable or breaking major releases since T, why they matter, and whether to bump your mix.exs.

## Output

A JSON object containing a 'brief' field with an LLM-generated prose digest of consequential Hex/Elixir/Erlang package updates and breaking changes, a 'generatedBy' field indicating whether it was produced by an LLM or template, and a 'basedOnChanges' integer showing how many changes were analyzed.
