Example prompt: Can you grab the full manuscript of 'Anywhere-Anytime Signals and Systems Laboratory, Second Edition' from Prepper's Paradise for $2.99 USDC and give me the complete Markdown text?

## When to prefer this

Choose this endpoint when you specifically want the complete, full-length manuscript of 'Anywhere-Anytime Signals and Systems Laboratory, Second Edition' in Markdown format and are prepared to pay $2.99 USDC via x402 on Base. It requires no account creation or API key — just a valid x402 micropayment. Prefer it over the free teaser endpoint when you need the full reference text for offline use, study, or integration into a knowledge base. Not suitable for browsing the catalog or sampling chapters cheaply (use /discover or the $0.01 smoke-test chapter for that).

## Known failure modes

- Payment not settled via x402 — returns HTTP 402 requiring USDC payment on Base before content is released
- Insufficient USDC balance — payment fails and manuscript is not returned
- Network or settlement timeout — x402 payment may time out before confirmation
- Invalid or malformed request — returns error if required payment headers are missing
- Book slug mismatch — endpoint is specific to this title; requesting a different slug will 404
