PaperPod

Isolated, agent-native sandboxes for code execution, live preview URLs, browser automation, 50+ tools (ffmpeg, sqlite, pandoc, imagemagick), LLM inference, and persistent memory — all via CLI or HTTP, no SDK or API keys required. Billed per second of compute usage and topup via stripe or x402.

## Quick Start

```bash
curl -X POST https://paperpod.dev/login -d '{"email":"[email protected]"}'  # Verify and get token
npm install -g @paperpod/cli
ppod login <token> && ppod help
```

## Authentication

**Step 1: Get a token**
```bash
curl -X POST https://paperpod.dev/login -d '{"email":"[email protected]"}'
# Check email → click magic link → copy token (pp_sess_...)
```

**Step 2: Use the token** (pick one method)

| Method | How | Best for |
|--------|-----|----------|
| **CLI login** | `ppod login pp_sess_...` | Everyday, Interactive use |
| **Env var** | `export PAPERPOD_TOKEN=pp_sess_...` | Scripts, CI/CD |
| **Per-request** | `-H "Authorization: Bearer pp_sess_..."` | HTTP one-shots |

Tokens expire in **15 days**. On `EXPIRED_TOKEN` error, re-authenticate via `POST /login`.

### CLI Examples

```bash

ppod exec "python -c 'print(2+2)'"
ppod exec "npm init -y && npm install express"
# Start server + expose (--bind 0.0.0.0 required for public access)
ppod start "python -m http.server 8080 --bind 0.0.0.0"
ppod expose 8080  # → https://8080-{sandbox-id}-p8080_v1.paperpod.work (stable URL)
# Browser with tracing
ppod browser:screenshot https://example.com --trace debug.zip
# Persistent storage (survives sandbox reset)
echo '{"step":3}' | ppod mem:write state.json
# Built-in tools (50+ available: ffmpeg, sqlite3, pandoc, imagemagick, git, jq, ripgrep...)
ppod exec "ffmpeg -i input.mp4 -vf scale=640:480 output.mp4"  # Video processing
ppod exec "sqlite3 data.db 'SELECT * FROM users'"             # Database queries
ppod exec "convert image.png -resize 50% thumbnail.png"       # Image manipulation
```

## Key Notes

- **Sandboxes are isolated** — each user gets their own container with a full Linux environment; you can only affect your own ephemeral sandbox
- **Sandbox is ephemeral** — use Agent Memory (`/memory/*`) for persistence
- **Working directory is `/workspace`** — relative paths like `file.txt` resolve to `/workspace/file.txt`
- **Servers must bind to `0.0.0.0`** for public access
- **Ports 3000-3010 are reserved** — use 8080, 5000, 4000, etc.
- **Browser sessions** — Each command creates an ephemeral session. Use `browser:acquire` for multi-command session reuse, `--trace` to capture Playwright traces

## Billing
