send_postcardSend a physical handwritten postcard to a US mailing address. Postals prints it with real robotic handwriting (pen and ink) and mails it via USPS. Delivery in 3-5 business days. Cost: $4.99 per card. Provide the recipient's address, a message (max 400 chars), and optionally an image URL for the card front. If no image is provided, uses the configured default card.generate_messageGenerate a personalized handwritten message for a postcard based on context about the recipient. Returns a ready-to-use message you can pass directly to send_postcard. Uses AI if Cloudflare credentials are configured (CLOUDFLARE_ACCOUNT_ID + CLOUDFLARE_API_TOKEN); otherwise returns a structured prompt you can use to compose the message yourself.
