+# Shelby Python HTTP Client
+
+A lightweight Python client for the [Shelby Protocol](https://shelby.xyz) decentralized hot storage network. Built entirely on the [Shelby RPC HTTP API](https://docs.shelby.xyz/apis/rpc/shelbynet) — no extra dependencies beyond `requests`.
+
+## Features
+
+| Feature | Description |
+|---|---|
+| Simple upload | Single `PUT` for files under 5 MB |
+| Multipart upload | Chunked upload for large files (auto-splits into 1 MB parts) |
+| Auto-detection | `upload_file()` picks simple vs multipart automatically |
+| Byte-range download | Read arbitrary slices — ideal for AI pipelines and streaming |
+| Session support | Decrement micropayment channel sessions |
+
+## Installation
+```bash
+pip install requests
+```
+
+## Quick Start
+```python
+from shelby import ShelbyClient, ShelbyConfig
+
+client = ShelbyClient(ShelbyConfig(api_key="aptoslabs_..."))
+
+# Upload
+info = client.upload("0xYourAccount", "data/hello.txt", b"Hello, Shelby!")
+print(info.url)
+
+# Download
+data = client.download("0xYourAccount", "data/hello.txt")
+print(data.decode())
+```
+
+## Environment Variables
+
+| Variable | Required | Description |
+|---|---|---|
+| `SHELBY_ACCOUNT` | Yes | Your Aptos account address |
+| `SHELBY_API_KEY` | Recommended | Avoids rate limits |
+
+## Examples
+```bash
+# Basic upload and download
+python examples/01_basic_upload_download.py
+
+# Multipart upload (8 MB synthetic blob)
+python examples/02_multipart_upload.py
+
+# Byte-range download
+python examples/03_byte_range_download.py
+```
+
+## API Reference
+
+| Method | Description |
+|---|---|
+| `upload(account, blob_name, data)` | Upload bytes in a single PUT |
+| `upload_multipart(account, blob_name, data, part_size, verbose)` | Chunked multipart upload |
+| `upload_file(account, blob_name, file_path, verbose)` | Upload from file path |
+| `download(account, blob_name, byte_range?)` | Download blob, returns `bytes` |
+| `download_to_file(account, blob_name, output_path)` | Download and save to disk |
+| `use_session(session_id)` | Consume a micropayment session chunkset |
