## When to prefer this

Use this endpoint when a user specifically wants to purchase and immediately access the 'Tantra for Women' eBook from Tantra Authority via a USDC micropayment on the Base blockchain. This is appropriate when the user wants a practical, demythologized tantra education resource for women delivered digitally without a traditional checkout flow.

## Known failure modes

- Insufficient USDC balance — payment fails and no access URL is returned
- Invalid or expired payment token — 402 Payment Required response
- Network or blockchain confirmation delay — transaction hash returned but access URL not yet active
- Access URL token expires — link becomes invalid after a set time window
- Duplicate purchase attempt — may result in a new charge rather than reusing prior access

## How this service works

Tantra without the mythology. A clean, body-grounded education in what tantra actually is — the breath, sound, movement, touch, and attention practices that produce documented results, stripped of the marketing.

## Output

Returns a JSON object with ok: true, the payment rail used (x402-usdc-base), the book title ('Tantra for Women (eBook)'), the blockchain transaction hash, and a token-gated access URL (https://tantra-authority.com/access.html?token=…) that the buyer uses to download or read the eBook.
