## Install

```bash
pip install fontfyi                # Core engine (zero deps)
pip install "fontfyi[cli]"         # + Command-line interface
pip install "fontfyi[mcp]"         # + MCP server for AI assistants
pip install "fontfyi[api]"         # + HTTP client for fontfyi.com API
pip install "fontfyi[all]"         # Everything
```

## Quick Start

```python
from fontfyi import get_font, css_family, google_fonts_url, parse_variants

# Look up a font
font = get_font("inter")
print(font["family"])       # Inter
print(font["category"])     # sans-serif
print(font["designer"])     # Rasmus Andersson

# Parse weight variants
weights, italic = parse_variants(font["variants"])
print(weights)              # [100, 200, 300, 400, 500, 600, 700, 800, 900]
print(italic)               # True

# Generate CSS
print(css_family("Inter", "sans-serif"))
# 'Inter', sans-serif
print(google_fonts_url("Inter", [400, 700]))
# https://fonts.googleapis.com/css2?family=Inter:wght@400;700&display=swap
```

## Font Pairings & Stacks

```python
from fontfyi import (
    search, popular, by_category, get_stack,
    get_pairings_for, featured_pairings, FONT_STACKS,
)

# Search fonts
results = search("mono")
for f in results:
    print(f"{f['family']} ({f['category']})")

# Top 10 most popular fonts
for f in popular(10):
    print(f"{f['popularity_rank']}. {f['family']}")

# Font stacks (CSS-ready)
stack = get_stack("system-ui")
print(stack.stack)
# system-ui, -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, ...

# Font pairings with rationale
for p in get_pairings_for("inter"):
    print(f"{p.heading} + {p.body} (score: {p.score})")
    print(f"  {p.rationale}")
    print(f"  Mood: {p.mood}")
```

## Command-Line Interface

```bash
pip install "fontfyi[cli]"

fontfyi info inter                     # Font metadata table
fontfyi search mono                    # Search fonts by name
fontfyi css inter                      # CSS import snippet
fontfyi pair inter                     # Font pairing suggestions
fontfyi popular                        # Top fonts by popularity
fontfyi stacks                         # Font stack presets
```

## MCP Server (Claude, Cursor, Windsurf)

Add font tools to any AI assistant that supports [Model Context Protocol](https://modelcontextprotocol.io/).

```bash
pip install "fontfyi[mcp]"
```

Add to your `claude_desktop_config.json`:

```json
{
    "mcpServers": {
        "fontfyi": {
            "command": "python",
            "args": ["-m", "fontfyi.mcp_server"]
        }
    }
}
```

**Available tools**: `font_info`, `font_search`, `font_css`, `font_pairings`, `font_stacks`, `popular_fonts`

## REST API Client

```bash
pip install "fontfyi[api]"
```

```python
from fontfyi.api import FontFYI

with FontFYI() as api:
    info = api.font("inter")           # GET /api/font/inter/
    css = api.css("inter")             # GET /api/font/inter/css/
    results = api.search("mono")       # GET /api/search/?q=mono
    pairings = api.pairings("inter")   # GET /api/pairings/inter/
    stacks = api.stacks()              # GET /api/font-stacks/
```
