X to Kindle

Convert X/Twitter posts into Kindle-readable documents via email.

Requirements

• Gmail account with App Password (or other SMTP setup)
• Kindle email address (found in Amazon account settings)

Workflow

When user shares an X link:

1. Extract content via fxtwitter API:

```

https://api.fxtwitter.com/status/

```

Extract from URL: twitter.com//status/ or x.com//status/

1. Format as HTML file (save to /tmp):

```html

@{author_handle}

{tweet_text}

{timestamp}

View on X

```

1. Send via SMTP with HTML as ATTACHMENT (Kindle requires attachment, not inline HTML):

```python

from email.mime.multipart import MIMEMultipart

from email.mime.text import MIMEText

from email.mime.base import MIMEBase

from email import encoders

msg = MIMEMultipart()

msg['Subject'] = "Tweet from @handle"

msg['From'] = from_email

msg['To'] = kindle_email

# Plain text body (not the content)

msg.attach(MIMEText("Article attached.", 'plain'))

# HTML file as attachment - THIS IS REQUIRED

with open("/tmp/article.html", "rb") as f:

attachment = MIMEBase('text', 'html')

attachment.set_payload(f.read())

encoders.encode_base64(attachment)

attachment.add_header('Content-Disposition', 'attachment', filename='article.html')

msg.attach(attachment)

```
