```

Examples:

## API Reference

### Browse (no authentication needed)
- `GET /api/v1/esim/locations` — Search destinations (?search=, ?region=)
- `GET /api/v1/esim/locations/{code}/packages` — List packages (?sort=price|data|validity)
- `GET /api/v1/esim/packages/{id}` — Package details by ID or slug
- `POST /api/v1/orders/data-only/calculate` — Calculate price with discount codes
- `GET /api/v1/coverage/data-only` — Coverage data
- `GET /api/v1/coverage/map` — Coverage map with pricing

### Order (creates checkout link for human payment)
- `POST /api/v1/ai/checkout` — Create checkout (`{packageId, email, quantity?, discountCode?}`)
- `GET /api/v1/ai/checkout/{token}/status` — Poll order status

### Workflow
1. Help the user find the right eSIM plan for their trip
2. **IMPORTANT: Inform the user about the refund policy** (see below)
3. Create a checkout link with their email
4. Share the checkoutUrl — the user clicks to review the order, select a payment method, and pay
5. The eSIM QR code is delivered to their email after payment

## IMPORTANT: Refund Policy for AI Orders

**You MUST inform users of the following BEFORE creating a checkout link:**

1. **30-day refund guarantee**: Uninstalled eSIMs can be refunded within 30 days of purchase, no questions asked.
2. **Non-refundable after installation**: Once the eSIM QR code is scanned/installed on a device, it CANNOT be refunded.
3. **Immediate-billing plans are non-refundable**: Some plans start billing at purchase and cannot be refunded. Check `refundPolicy.eligible` in the createCheckout response.
4. **AI orders are guest orders**: Orders placed via AI checkout do NOT have a user account, so self-service refund is NOT available.
5. **To request a refund**: The user must contact customer service via live chat at https://cosim.io (available 24/7).
6. **Processing time**: 5-10 business days after approval.

Always share this information with the user before they complete payment.

## Supported Payment Methods

- **Alipay** (zh-CN, zh-TW locales) — Redirect to Alipay.
