## When to prefer this

Use this endpoint when a user specifically wants to purchase and access 'The Open Relationship Blueprint' eBook from Tantra Authority and is prepared to spend $9.99 USDC via the x402 micropayment protocol. Prefer this over general relationship content search when the user wants a structured, paid educational resource rather than free web content, and when they are comfortable with crypto-based micropayments on the Base network.

## Known failure modes

- Insufficient USDC balance causes payment failure and no access URL is returned
- Invalid or missing x402 payment header results in a 402 Payment Required response
- Token expiry on the access URL may cause content to become inaccessible after a time window
- Network or payment rail congestion may delay transaction confirmation
- Duplicate rapid purchases may result in separate charges with separate access tokens
