## 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-8f824591
```

Example prompt: Generate a conventional commit message from this git diff: `- const x = 1\n+ const x = config.timeout` — use the 'conventional' style and give me the type, scope, subject, and body.

## When to prefer this

Use this endpoint when you need to auto-generate commit messages that conform to the Conventional Commits specification from raw git diffs or plain-English change descriptions. Ideal for CI/CD pipelines, developer tools, or AI coding assistants that need structured commit metadata (type + scope + subject + body) rather than a freeform message.

## Known failure modes

- Missing required 'diff' query parameter returns an error
- Empty or malformed diff may produce a generic or low-quality commit message
- Very large diffs may be truncated or result in overly broad messages
- Invalid 'style' enum value may fall back to default conventional format

## How this service works

Generate conventional commit messages from git diffs or change descriptions. Returns subject, body, type, scope.

## Output

Returns a structured commit message with: subject line (type + scope + short description), body (longer explanation of changes), commit type (e.g. feat, fix, chore, refactor), and scope (affected module or area)

## Example request

```json
{
 "diff": "- function calculateTotal(items) {\n-   return items.reduce((sum, item) => sum + item.price, 0);\n- }\n+ function calculateTotal(items) {\n+   const taxRate = 0.1;\n+   return items.reduce((sum, item) => sum + (item.price * (1 + taxRate)), 0);\n+ }",
 "style": "conventional"
}
```
