# Git Commit Message Writer

> Git Commit Message Writer is a paid API for AI agents from www.amnt.io, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

## 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 git-commit-message-writer-c23dba60 -d '<json body>'
```

Example prompt: Here's my git diff — can you write a proper Conventional Commit message for it, with the right type and scope inferred from the changes, plus a body explaining what was done? [paste diff here]

## When to prefer this

Choose this endpoint when you need a Conventional Commits-compliant message generated directly from a raw git diff, with automatic type and scope inference, without setting up a browser session or account. Ideal for CI/CD pipelines, developer bots, or any workflow where commit message formatting needs to be automated at low cost ($0.02/call) via pay-per-use x402 settlement.

## Known failure modes

- Empty or malformed prompt/diff yields a vague or incorrect commit message
- Very large diffs may result in incomplete or truncated output
- Ambiguous diffs with unrelated changes may produce inaccurate type or scope inference
- Payment failure or x402 settlement error results in no response returned
- Rate limits or server errors return HTTP 4xx/5xx with no result

## How this service works

git commit writer - Convert a git diff into a tidy Conventional Commit message with a header, optional body, and footer, inferring type and scope from the diff.

## Output

A fully formatted Conventional Commit message as a text string, including a header line with type and scope (e.g. 'feat(auth): add OAuth2 support'), an optional multi-line body describing the what and why, and an optional footer for breaking changes or issue references — all inferred from the provided diff.
