## AI Agent Integration Guide

### Overview
co:sim provides a REST API that AI agents can use to help travelers find and purchase eSIM data plans. The complete workflow is:

1. **Search** — Find destinations matching the user's travel plans
2. **Compare** — List and compare packages for a destination
3. **Calculate** — Get exact pricing with optional discount codes
4. **Checkout** — Create a payment link for the user
5. **Track** — Monitor order status until completion

### API Base URL
`https://cosim.io/api/v1`

### OpenAPI Specification
`https://cosim.io/openapi.yaml`

### MCP Server (recommended for MCP-capable agents)

co:sim runs a Model Context Protocol server at `https://cosim.io/mcp`
(Streamable HTTP transport, stateless, no authentication). MCP-capable clients
(Claude, ChatGPT developer mode, Cursor, and other MCP hosts) can connect
directly and get typed tools instead of raw REST calls:

- `search_destinations` / `list_packages` / `get_package` — browse the catalog
- `recommend_plans` — up to 3 plans for a trip (countries + days + usage)
- `list_promotions` — active co:sim campaigns and coupon codes (call before create_checkout so users get the best price)
- `create_checkout` — create a human-payable checkout link
- `check_order_status` — poll a checkout

Registry name: `io.cosim/esim` (official MCP Registry). The REST endpoints
below remain fully supported for agents without MCP.

### REQUIRED: User-Agent Header

All API requests MUST include a `User-Agent` header identifying your client application and the AI model powering it:

```
User-Agent: {ClientName}/{ClientVersion} ({Model}/{ModelVersion})
```

**Format:**
- `ClientName` — your application or plugin name (alphanumeric + hyphens)
- `ClientVersion` — semantic version of your client (e.g. 1.2.0)
- `Model` — the AI model identifier (e.g. gpt-4o, claude-sonnet-4-20250514, gemini-1.5-pro)
- `ModelVersion` — model version or snapshot date

**Examples:**
- `ChatGPT-Plugins/1.2.0 (gpt-4o/2024-08-06)`
- `Claude-MCP/0.5.1 (claude-sonnet-4-20250514/20250514)`
- `MyTravelBot/2.1.0 (gpt-4-turbo/2024-04-09)`
- `CustomAgent/1.0.0 (gemini-1.5-pro/001)`
- `Coze-Bot/3.0.0 (doubao-pro-32k/2024-06)`

Requests without a proper User-Agent may be rate-limited or rejected.

### Endpoints

### Example Conversation Flow

**User**: "I'm traveling to Japan for 10 days, what eSIM should I get?"

**AI Agent**:
1. Call `GET /api/v1/esim/locations/JP/packages?sort=price`
2. Present options: "Here are Japan eSIM plans..."
3. User selects a plan
4. **Inform the user about the refund policy** (see below)
5. Call `POST /api/v1/ai/checkout` with packageId + user's email
6. Share checkout link: "Click here to complete your purchase: [checkoutUrl]"
7. Optionally poll status to confirm payment

---

## IMPORTANT: Refund Policy for AI Orders

**AI agents MUST inform users of the following BEFORE creating a checkout link.**
The createCheckout response carries the authoritative, per-order wording in `refundPolicy.reason` and `installValidity.note` — relay those verbatim rather than restating the generic rules below (they already account for immediate-billing plans, free items, and coupon-shortened install windows).

1. **30-day refund guarantee**: Uninstalled eSIMs can be refunded within 30 days of purchase, no questions asked — but never past the install deadline (see point 7). `refundPolicy.refundableUntil` carries the effective date.
2. **Non-refundable after installation**: Once the eSIM QR code is scanned/installed on a device, it CANNOT be refunded.
3. **Immediate-billing plans and free items are non-refundable**: Some plans (billingStart: "purchase") start billing immediately upon purchase, and free (100%-discounted) items cannot be refunded. The API response includes `summary.billingStart` and `refundPolicy.eligible` to indicate this. Always check these fields.
4. **AI orders DO support self-service refunds**: Although orders placed via AI checkout start as guest orders (no `userId`), the user can sign in (or create an account) at https://cosim.io with the same email this order was placed with. Past guest orders are automatically claimed on first sign-in, after which the user can refund eligible eSIMs from "My eSIMs" without contacting support.
5. **Live chat is a fallback only**: If the user cannot or does not want to sign in, they can still contact customer service via live chat at https://cosim.io (available 24/7) to request a refund.
6. **Processing time**: 5-10 business days after approval.
7. **Install deadline**: eSIMs must be installed within `installValidity.days` days of purchase (some coupons shorten this window — the response reflects the effective value). Uninstalled eSIMs are automatically cancelled after the deadline, which also ends refund eligibility. After payment, `GET /api/v1/ai/checkout/{token}/status` returns the exact deadline in `installValidity.installBy`.

**Example message to share with user before checkout:**
> "Before you proceed: install this eSIM within 30 days of purchase (by 2026-08-02) — it's automatically cancelled after that. As long as it hasn't been installed, you can get a full refund within that window. Once installed, it cannot be refunded. To refund, sign in at cosim.io with this same email — your order will be linked to your account automatically and you can refund it from 'My eSIMs'. Live chat is also available if you prefer."

## Supported Payment Methods

The AI checkout page automatically shows relevant payment methods based on the user's locale:
- **Credit/Debit Card** (all locales) — Visa, Mastercard, AMEX, UnionPay, JCB. Stripe Checkout also offers Apple Pay & Google Pay as built-in options.
- **Alipay** (zh-CN, zh-TW locales) — Redirect to Alipay for payment.
- **WeChat Pay** (zh-CN, zh-TW locales) — QR code displayed inline on the checkout page.
- **Amazon Pay** (ja locale) — Redirect to Amazon Pay for payment.

## AgentCard Integration (Automated Payment)

AI agents using virtual debit cards (e.g., AgentCard) can automate payment:

1. Create a checkout link via `POST /api/v1/ai/checkout`
2. Call `POST /api/v1/ai/checkout/{token}/pay` with `{"paymentMethod": "card"}` to get the Stripe Checkout URL
3. Use the AgentCard `pay_checkout` or `fill_card` tool to fill virtual card details on the Stripe Checkout page
4. Poll `GET /api/v1/ai/checkout/{token}/status` to confirm payment
5. The eSIM is delivered to the user's email automatically

## Payment Methods
- **Credit/Debit Card**: Visa, Mastercard, American Express, UnionPay, JCB
- **Digital Wallets**: Apple Pay, Google Pay (via Stripe Checkout)
- **Regional**: Alipay, WeChat Pay (CN/HK/TW/SG/MY), Amazon Pay (Japan)
- **Balance**: Global Prepaid balance (authenticated users only)

## Refund Policy
- **Uninstalled eSIMs**: Full refund within 30 days of purchase, no conditions
- **Installed eSIMs**: Not eligible for refund (unless due to technical issues on our side)
- **Expired-uninstalled eSIMs**: NOT eligible for refund. If the pre-installation deadline (preInstallDays from purchase) passes without the eSIM being installed, the profile expires permanently and is non-refundable.
- **AI/Guest orders**: Self-service refund IS available — the user signs in (or creates an account) at https://cosim.io with the order email; past guest orders are auto-claimed on first sign-in, and the user can then refund eligible eSIMs from "My eSIMs". Live chat at https://cosim.io remains a fallback.
- **Processing**: 5-10 business days

## eSIM Pre-Installation Validity (preInstallDays)
- Every Data-Only plan has a `preInstallDays` field: the number of days from purchase within which the eSIM must be installed (QR code scanned).
- Typical values: 30–180 days. The exact value is plan-specific.
- `preInstallDays` is returned by the /api/v1/esim/recommend endpoint and shown in PackageSummary objects.
- IMPORTANT: `supplierPreInstallDays` is an internal admin field and is NEVER included in any public API response or surfaced to users. Always use `preInstallDays` (the customer-facing value).
- Always communicate preInstallDays to users at checkout: e.g. "Install within 90 days of purchase or the eSIM expires."
