Free sample, no account needed

The mandala book’s sample field contains free A4 and US Letter download URLs, three designs per PDF, and a personal-use license. Follow redirects to retrieve the PDF. No payment token, email, Google login, or purchase consent is required for a free sample. Other books currently have sample: null.

PDF purchases

Compatible agents can use Machine Payments Protocol (MPP) with an authorized Stripe Shared Payment Token. No Google password, card number, or merchant API key should be given to an assistant. Purchases must be requested by the buyer, within their approved budget, with their explicit agreement to the digital-download terms.

The agent creates an order, checks the tax-inclusive total, handles the payment challenge, and receives a receipt and private download links once payment is verified. An agent cannot buy paperbacks through this API.

Your library

Keep the private order token supplied by your assistant. You can use it with Google sign-in to save the purchase to your library. We do not link orders to accounts based only on an email address.

Amazon paperbacks

Where a verified Amazon link is available, follow it to Amazon for current pricing and checkout. Entries marked “link pending” are placeholders and cannot be purchased through the catalog.

Purchase terms

PDFs are for personal use, with A4 and US Letter formats included. Nothing is shipped. See our purchase terms and privacy notice.
