  nscout checks PyPI and TestPyPI availability, extracts rich metadata,  
  formats results into clean readable tables, and integrates perfectly into  
  CI environments via JSON output.  
  Blazing-fast in-memory caching keeps repeated lookups instant.

## nscout is designed to be:
- quick to use  
- informative out of the box  
- script-friendly  
- safe for automation (JSON mode, quiet mode)  
- ideal for package authors checking names before publishing


## Why nscout?

Choosing a package name sounds simple — until PyPI tells you it isn’t.  
With more than half a million packages published, many good names are taken,  
and simply knowing “yes/no” isn’t enough anymore.

nscout gives you **the story behind the name**, not just the answer:

- If a name is available → you're ready to publish.  
- If it’s taken → you instantly see who owns it, how active it is,  
  what it does, and whether it’s safe to choose something similar.  
- If PyPI is having trouble → you get structured error information,  
  not cryptic failures.

It’s fast, scriptable, CI-friendly, and ideal for anyone publishing Python packages.


## Features

- Check whether a package name is **taken** or **not taken**
- Automatic metadata fetch from PyPI:
  - latest version
  - summary/description
  - author + author email
  - license
  - homepage & project URLs
  - Python requirement
  - release count
  - latest release timestamp
- Clean pretty layout for **single package** checks
- Compact table layout for **multiple packages**
- File mode (`-r file.txt`) for batch operations
- JSON mode for scripts & CI tools
- Quiet mode for log-friendly output
- In-memory caching for ultra-fast repeated lookups
- Works with both PyPI and TestPyPI

```bash
nscout -r names.txt
```

---

### **JSON output (for CI / scripts)**

```bash
nscout --json requests
```

Example:

```json

## 🧠 Exit Codes

| Code | Meaning                      |
| ---- | ---------------------------- |
| 0    | All names available          |
| 1    | At least one name is taken   |
| 4    | Network error / PyPI failure |

These are safe for CI pipelines.
