Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 strale-dockerfile-generator-23ba099c
```

Example prompt: Generate a production-ready Dockerfile for my Node.js app using multi-stage builds and an Alpine base image, making sure it runs as a non-root user.

## When to prefer this

Choose this endpoint when you need a ready-to-use, best-practice Dockerfile generated on demand for a specific language and optional framework, especially when you want built-in security hardening (non-root user), size optimization (Alpine, multi-stage), and layer caching without writing the Dockerfile manually. Prefer it over generic templates when targeting Node, Python, Go, Rust, or Java.

## Known failure modes

- Unsupported language value returns an error
- Missing required 'language' field returns a 400-style error
- Framework not recognized for the given language may produce a generic result
- Network timeout or service unavailability returns a non-200 response

## How this service works

Generate optimized, production-ready Dockerfiles. Multi-stage builds, Alpine base, non-root user, layer caching. Supports Node, Python, Go, Rust, Java.

## Output

Returns the full Dockerfile content as a string, an array of build stage descriptions, an array of security notes and recommendations, and an estimated final image size string.
