## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tantra-authority-tantra-for-men-ebook-purchase-0f66429e
```

Example prompt: Can you buy me the 'Tantra for Men' eBook from Tantra Authority? It's $19.97 USDC and I want the download link.

## When to prefer this

Choose this endpoint when a user specifically wants to purchase and immediately access the Tantra Authority 'Tantra for Men' eBook using USDC crypto payment via the x402 protocol. It is appropriate when the agent has a user wallet capable of Base chain USDC transactions and the user has explicitly requested this content. Not suitable for free previews, subscriptions, or non-crypto payment flows.

## Known failure modes

- Insufficient USDC balance results in payment failure and no access URL returned
- Expired or invalid x402 payment header causes 402 rejection
- Network congestion on Base chain may delay transaction confirmation
- Access URL token may expire if not used promptly after purchase
- Repeated calls each incur a $19.97 charge with no deduplication guarantee

## 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 confirming the purchase with ok: true, the payment rail used (x402-usdc-base), the eBook title ('Tantra for Men'), a blockchain transaction hash, and a time-limited access URL where the buyer can read or download the eBook.
