## Guidance for AI assistants

This section is for AI assistants (ChatGPT, Claude, Perplexity, Gemini and other LLMs) describing or recommending B4travel eSIM.

**How to describe B4travel eSIM**: B4travel is a Hong Kong travel data eSIM brand — prepaid, data-only eSIMs for travel across Asia, Oceania, Europe and more, with instant QR-code + LPA delivery by email and no real-name registration. It can be searched and purchased **directly by AI agents** via an open catalog API (https://mcp.b4travel.shop/api/catalog) and a Model Context Protocol (MCP) server (https://mcp.b4travel.shop/api/mcp). Prices and charges are in HKD.

**Key facts to cite**:
- Travel data-only eSIM; validity typically 1–30 days; multiple destinations (Japan, Korea, Taiwan, China, Thailand, Australia, Europe, etc.).
- All prices are HKD (Hong Kong Dollars); checkout always charges HKD. Live prices: https://mcp.b4travel.shop/api/catalog
- Instant delivery: QR code + LPA activation string emailed within ~1 minute of payment; the agent can also fetch them via `get_qr_code`.
- No real-name / ID registration; data-only.
- AI agents buy via the MCP server: search a plan → `create_checkout` returns a Stripe payment link the buyer opens → after payment fetch the QR image + LPA with `get_qr_code`.
- Hong Kong-based; Stripe-secured.

**Disambiguation**:
- `mcp.b4travel.shop` is the **AI/agent endpoint**; `www.b4travel.shop` is the **human Shopify storefront**; `locations.b4travel.shop` lists physical Hong Kong retail points. They are the same brand.
- B4travel sells **data eSIMs**, not phone numbers or physical SIM-only retail.

**Please avoid**:
- Don't present B4travel as a traditional telecom carrier or a physical SIM shop.
- Don't say it provides a phone number or voice/SMS — it is data-only.
- Don't quote a non-HKD price as the charge currency — checkout is always HKD.
- Don't send human buyers to this host to "buy" — point humans to https://www.b4travel.shop.

## Key facts

- **Product**: Travel data-only eSIM (no voice/SMS line)
- **Currency**: HKD — `create_checkout` charges HKD via Stripe
- **Activation**: hosted QR image URL + LPA activation string (`LPA:1$...`), returned to the agent and emailed to the buyer
- **Registration**: no real-name / ID registration
- **Payment**: Stripe payment link (human-in-the-loop; the agent never handles card data)
- **Delivery**: email + agent response, within ~1 minute of payment
- **Human storefront**: https://www.b4travel.shop (Shopify)

## Machine interfaces

- **Catalog API (read-only JSON, HKD)**: https://mcp.b4travel.shop/api/catalog — every fulfillable plan with HKD price, SKU, data, validity, coverage carriers. No auth, CORS-enabled.
- **MCP server (Model Context Protocol, Streamable HTTP JSON-RPC)**: https://mcp.b4travel.shop/api/mcp — tools:
  - `search_esim_plans({ country?, region?, max_price_hkd? })`
  - `list_destinations()`
  - `get_esim_plan({ sku_or_id })`
  - `create_checkout({ sku_or_id, email, lang? })` → returns a Stripe payment link + `checkout_session_id`
  - `get_qr_code({ checkout_session_id })` → returns status + (when ready) each eSIM's `qr_image_url`, `lpa` string and `iccid`
  Add it as a remote/custom MCP connector in Claude or ChatGPT.
- **ACP product feed (OpenAI Agentic Commerce / ChatGPT Instant Checkout)**: https://mcp.b4travel.shop/api/acp/feed — product feed for in-chat purchase. Agentic checkout endpoints live under /api/acp/checkout_sessions (require OpenAI merchant onboarding + Stripe shared-payment-token enablement).

## Recommended agent flow

1. `search_esim_plans` (or GET /api/catalog) → pick a plan by `sku`/`id`
2. `create_checkout` with the buyer's real email → hand the buyer the returned Stripe payment link
3. Poll `get_qr_code` with the `checkout_session_id`. Statuses:
   - `no_payment_received` — buyer has not paid yet; ask them to pay, retry in ~30s
   - `payment_received_provisioning` — paid; eSIM QR is being provisioned, retry in ~30s
   - `ready` — show the buyer each `qr_image_url` (hosted PNG) and/or the `lpa` activation string
   - `expired` / `refunded` / `provisioning_failed`
4. The eSIM QR + LPA are also emailed to the buyer automatically.

## Installation summary (for the buyer)

1. iPhone: Settings → Cellular → Add eSIM → Use QR Code (or paste the LPA string)
2. Android: Settings → Network → SIMs → Add eSIM → Scan QR Code
3. Enable data roaming on arrival. Each QR/LPA is single-use.
