# AI Hub Add-On

## Product description

The [AI Hub Add-On](/agentic-commerce/ai-hub/overview.md) product enables merchants to make their product catalog, pricing, and availability visible and purchasable within Generative AI channels such as ChatGPT, Google Gemini, and others. It helps enterprises turn conversational AI interfaces into revenue-ready sales channels. It does this securely, accurately, and at scale.

AI Hub provides ready-made modules built for each GenAI channel and its technical specifications. These modules ensure that product data, availability, and pricing from the commercetools environment are current and understandable by AI systems. Shoppers can then receive accurate information and complete purchases directly within the AI conversation.

When a shopper interacts with a GenAI channel like ChatGPT or Google Gemini, AI Hub connects in real time to your commercetools data. It surfaces relevant products, validates stock, and enables checkout through supported payment partners.

## Defined scope

AI Hub includes everything required to make product, pricing, and inventory data discoverable and purchasable within Generative AI channels. This includes infrastructure, APIs, and ready-to-use channel modules.

Each module follows the technical specifications of its respective AI platform, ensuring accurate data exchange and compliance across all connected channels.

For functionality annotated with , default limits apply that can be extended via [Add-On products and services](/offering/add-ons.md).

## Compatibility

AI Hub is built on [commercetools](/offering/products-overview) and inherits its compatibility model.

### commercetools APIs

commercetools uses continuous delivery to deploy updates multiple times a day. This means there are no fixed release cycles; features are released as soon as they are ready, and issues are corrected promptly.

The commercetools APIs used by AI Hub are versionless, removing the need for version upgrades. Individual fields or actions may change as part of API evolution. These changes will not break existing solutions but might require adjustments.

If additional undocumented fields are sent in API requests, these can conflict with future new field names and cause runtime errors. Avoiding this is the responsibility of the customer.

### Platform integration specifications

AI Hub integrates with the commerce APIs of third-party AI shopping platforms (including OpenAI, Google, and Stripe) using open protocols such as the Universal Commerce Protocol (UCP). These specifications are defined, maintained, and evolved by the respective platform vendors independently of commercetools.

commercetools tracks changes to platform specifications and updates AI Hub components accordingly. However, changes driven by third-party platform spec updates, including protocol changes, new field requirements, or shifts in integration model, are outside the standard deprecation and compatibility commitments that apply to commercetools APIs. commercetools does not control the timelines of these changes.

The availability, uptime, and behavior of the AI shopping platforms themselves are also outside the scope of AI Hub compatibility commitments.

### SSL/TLS lifetime

To keep connections to the API secure at all times, SSL/TLS certificates are periodically renewed and replaced when adapting to newer security policies. A maximum of one certificate renewal per year is targeted. If security issues are found within encryption algorithms in use, certificates may be replaced more frequently.

## Limits

AI Hub is subject to contractual limits in addition to the [standard commercetools API limits](/api/limits). The specific allowances and overage rates for SKU-platform units, orders, catalog syncs, and additional platform integrations are defined in your contract. Contact your commercetools representative for details.

### SKU-platform unit definition

A Product Variant in commercetools is an SKU. For the purposes of AI Hub limits, the counted unit is the **SKU-platform unit**: one SKU synced to one AI shopping platform. Syncing the same SKU to two platforms counts as two SKU-platform units against the contracted allowance.

For example, a catalog of 30,000 product variants (SKUs) connected to two platforms (OpenAI and Google) consumes 60,000 SKU-platform units.

The following limits apply to all AI Hub contracts regardless of tier:

| Limit | Value |
| --- | --- |
| Full catalog syncs | Up to 1 per day |
| Price and availability updates | Up to every 15 minutes |
