How Shopify’s Catalog API Is Powering AI Shopping Agents
Shopify’s new Catalog API is more than just a technical update. It signals a major shift in how products are discovered online. By giving AI shopping agents like Perplexity and ChatGPT direct access to structured product data, Shopify is enabling real-time, intelligent discovery for millions of products across its platform.
This change transforms how shoppers find, compare, and purchase items. It also means retailers must optimise differently to remain visible. In this new ecosystem, structured data replaces backlinks, and content quality determines whether your products appear in an AI-generated shopping result.
What Is the Shopify Catalog API?
The Shopify Catalog API is a real-time data feed that delivers product information, including titles, prices, availability, categories, and metadata. This API allows discovery platforms and AI agents to access a clean, structured version of a store’s product catalogue without scraping web pages or relying on outdated feeds.
It unlocks faster, more accurate, and more scalable product discovery. Instead of crawling websites, AI tools can now query this API to find exactly what a user is looking for, filtered by real-time attributes and merchant-defined criteria.
Why This Changes Everything for Retail
With this update, AI shopping agents can fulfil product requests instantly, based on specific needs and preferences. For example, a user might type: “Find a breathable men’s running shoe under $120, available now.”
- Perplexity is confirmed as the first external platform with access
- ChatGPT, Shopify Copilot, and others are expected to follow
- Search is shifting from keyword-based to context-driven prompts
These agents no longer rely on ranking signals like backlinks or keyword stuffing. Instead, they parse the product feed directly. If your data is incomplete, duplicated, or missing context, you are unlikely to be included in their recommendations.
What AI Shopping Agents Can Now Do
The Catalog API gives AI agents new superpowers. They can interact with your store’s product data just like a well-trained assistant. The experience becomes faster, more accurate, and more contextual than ever before.
- Query all public Shopify products in real time
- Filter by brand, price, size, colour, availability, and more
- Deliver results based on use case, materials, care, or customer preferences
This unlocks curated discovery experiences, personalised search, and eventually even cross-store checkout. Instead of sending shoppers to a search engine, AI agents may complete their journey inside a single conversation.
Are Shopify Merchants Automatically Included?
Yes, most Shopify stores are already opted in. Unless a merchant has explicitly requested to be excluded, their product data is accessible via the Catalog API. But being listed is not enough.
To be visible, your content must be structured, complete, and tailored to how AI agents evaluate options. Poorly written descriptions, missing fields, or generic supplier data will be skipped over.
Key actions for Shopify merchants:
- Update every product field, from title to enriched metadata
- Replace duplicate supplier content with original, helpful copy
- Use Shopify’s new Knowledge Base objects to enrich data with context
- Align descriptions with product use cases and consumer intent
Why AI Agents Are Replacing Traditional SEO
Consumers are already shifting their habits. Many use ChatGPT, Perplexity, or Shopify Copilot to browse and buy. They ask a single question and expect results tailored to their needs, delivered instantly.
- Discovery happens in one prompt, not across pages
- Answers are based on structured relevance, not keyword matches
- Results show availability, price, and specs in real time
- Comparisons are automatic and contextual
Brands relying only on traditional SEO may soon be invisible to this growing segment of AI-driven shoppers. Agentic SEO is no longer a future consideration. It is already shaping online visibility today.
How Is Access to the Catalog API Controlled?
Shopify is carefully vetting partners. Perplexity is the first confirmed platform to gain full access. More are expected to follow, but access is limited to trusted, high-value integrations that protect merchant data.
To qualify, platforms must demonstrate:
- Clear value to Shopify merchants and their GMV
- Transparent data usage policies
- Security, compliance, and trustworthy behaviour
This controlled rollout helps ensure merchants benefit from new discovery models without exposing their data to misuse or harmful automation.

Websites with large product feeds from 500 to 100k+ sku’s, Optidan has a solution that can power your optimisation.
Is SEO still relevant?

Even with traditional SEO this data was important but often ignored due to the complexity, and resource to optimise at scale. This is why Optidan was built by retailers for retailers.

Optidan corrects this, and generates content to meet search algorithms at scale.
How does Optidan support this shift?
We rewrite, restructure, and sync your entire feed to meet the requirements of AI discovery platforms, ensuring your products are visible and ready.
