The complete 1362-page interleaved PDF (original beside restoration, full resolution) is available for $0.10 in stablecoin, paid over MPP (the Machine Payments Protocol). Payment is machine-to-machine — give the instruction below to an AI coding agent, which will pay the $0.10 and download the PDF for you:
Use the mppx CLI to pay for and download the Book of Kells PDF. Run:
npx mppx@latest --network mainnet -L \
https://bookofkells.vercel.app/api/download > book-of-kells.pdf
This makes an HTTP request that returns a 402 Payment Required, pays the
$0.10 USDC charge on the Tempo network from my mppx account, retries with
the payment credential, and follows the redirect (-L) to the full PDF,
saving the response body to book-of-kells.pdf. If I have no mppx account
yet, first run `npx mppx@latest account create` and fund it with a little
USDC on the Tempo network.
Requires an mppx account funded with a small amount of USDC on the Tempo network. The payment settles on-chain; there is no card checkout.
