## Supported Ecosystems

| Ecosystem | System ID | Example Package |
| --------- | --------- | --------------- |
| npm | `NPM` | `express`, `@types/node` |

```

## Workflow

Think step-by-step:

1. **Identify the ecosystem** from context:
   - `package.json` or `node_modules` → NPM
   - `requirements.txt`, `pyproject.toml`, `setup.py` → PYPI
   - `go.mod`, `go.sum` → GO
   - `Cargo.toml` → CARGO
   - `pom.xml`, `build.gradle` → MAVEN
   - `*.csproj`, `packages.config` → NUGET
   - `Gemfile` → RUBYGEMS
   - If unclear, ask the user

2. **Query the API** with curl (URL-en
