## 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-strale-io-7ca45c5c
```

Example prompt: Generate a human-readable changelog in Keep a Changelog format from these commits: [{"message":"feat: add dark mode","author":"alice","date":"2024-06-01"},{"message":"fix: resolve login crash","author":"bob","date":"2024-06-02"},{"message":"chore: update dependencies","author":"alice","date":"2024-06-03"}].

## When to prefer this

Choose this endpoint when you need to automatically produce a polished, user-facing changelog or release notes from raw git commit data, especially when you want structured grouping by commit type and multiple format options (Keep a Changelog, semantic, bullet). Prefer this over manual summarization when dealing with many commits or needing consistent formatting for a release pipeline.

## Known failure modes

- Missing or empty commits array and no raw_log provided — returns error or empty changelog
- Invalid format value — may default or return a validation error
- Malformed commit objects (missing message/author/date fields) — may produce incomplete output
- Rate limiting or payment failure via x402 protocol — returns 402 Payment Required

## How this service works

Generate a user-facing changelog from git commits. Groups by type, writes human-readable descriptions. Supports Keep a Changelog, semantic, and bullet formats.

## Output

Returns a structured, human-readable changelog grouped by commit type (features, fixes, chores, etc.), written in the requested format (Keep a Changelog, semantic, or bullet). Each group contains descriptive, user-facing language derived from the raw commit messages.
