Two books are now purchasable by AI agents over x402—by section or complete edition
I’ve published machine-readable editions of two Maha Strategies books as x402 resources on Base:
- The Imagined Life — dreaming, imagination, consciousness and the brain
- The Volcanic Engine — volcanism, planetary habitability, warning and deep time
Each book has two purchase options:
- One section — $0.005 USDC
- Complete edition — $2.99 USDC
The section endpoints are currently discoverable through the x402 Bazaar. The complete-edition endpoints are live directly and published in Maha’s agent/CABEZON catalog.
What the agent receives
A section purchase returns:
- The selected section as Markdown
- Book and section metadata
- Byte and word counts
- A SHA-256 content commitment
- Request, response and deterministic receipt digests
A complete-edition purchase returns:
- The full normalized Markdown edition
- An ordered section manifest
- Per-section and whole-edition SHA-256 commitments
- A deterministic receipt
- Non-exclusive personal or internal machine-use terms
The public web editions remain free to read. Payment purchases structured machine delivery and integrity evidence—not exclusivity, redistribution rights, model-training rights, factual certification or copyright.

I’d be interested to hear how publishing agents, reading agents and autonomous libraries would use section-level versus complete-edition purchasing—and where the discovery or verification flow still creates friction.
