Definition

An agent-ready product feed is a product feed carrying the full set of data an agent needs to search, compare and buy: identifiers, attributes, variants, current price and availability, delivery and returns.

What an agent-ready product feed is

A product feed was originally built for advertising and recommendations: ID, title, price, image, category. An agent choosing a product on the shopper’s behalf asks more questions: what colour is this variant, how much is delivery, can it be returned. If the answer is not in the data, the agent either picks another store or gets it wrong. In OpenAI’s words, the feed exists so that ChatGPT accurately indexes and displays your products with up-to-date price and availability.

What the specifications require (as of September 2026)

Requirement	OpenAI Product Feed Spec (ChatGPT)	Google Merchant Center and UCP
Required fields	item_id, title, description, url, brand, seller_name, image_url, availability, price	id, title, description, link, image_link, availability, price; brand for new products
Identifiers	gtin, mpn are optional	GTIN strongly recommended, MPN when there is no GTIN
Variants	group_id, variant_dict	item_group_id
Text length	title up to 150 characters, description up to 5,000	title up to 150, description up to 5,000
Format and updates	JSONL, CSV or TSV; full export over SFTP at least once a day	Price and availability match the landing page, structured data and checkout
Checkout	Separate integration, is_eligible_checkout flag	native_commerce attribute; UCP checkout in AI Mode and Gemini — US, Canada, Australia

How it differs from an advertising feed

Delivery and returns. The shipping, accepts_returns, return_deadline_in_days and return_policy fields — an agent needs them before payment, not after.
Reviews as numbers. review_count and star_rating — the agent compares products on them.
Seller. seller_name, and for checkout, links to the privacy policy and terms of sale.
Eligibility flags. is_eligible_search and is_eligible_checkout define which products can be found and which can be bought.

Feed data has to match the schema markup on the page and what the shopper sees at checkout. The purchase itself then runs through a protocol — ACP or UCP.

Feed readiness checklist

Check	Ready when
Identifiers	Every variant has a stable ID; GTIN is filled in for every product that has one
Titles and descriptions	Brand, model, key variant parameter; the description is factual, not promotional
Variants	Colour, size, volume — separate rows sharing one group_id
Price and availability	Match the website and checkout; exported at least once a day
Delivery and returns	Cost, delivery times, return window in days
Images	The main photo shows this exact variant
Data source	Attributes come from a PIM rather than being edited by hand in the feed

The feed is the first step towards agent-readiness: without it, checkout protocols have nothing to stand on.

Frequently asked questions

How is a feed for agents different from a feed for ads or recommendations?

An ads feed answers the question “should this product be shown?”, a recommendations feed answers “what should it be linked with?”. An agent feed has to answer every question the shopper has before paying: is this the right variant, how much is delivery, can it be returned. So it carries more fields — variants, delivery, returns terms, ratings — and the bar for fresh price and availability is higher.

How often should a feed for ChatGPT be updated?

Under OpenAI's specification as of September 2026, at least once a day, as a full catalogue export: incremental updates are not supported, and each export is treated as the source of truth. Availability and price should be updated as soon as an item sells out or a sale starts. If your prices change more than once a day, export more often.

Is GTIN mandatory?

It depends on the channel. In OpenAI's specification gtin and mpn are optional fields. In Google Merchant Center, whether GTIN is required depends on the product and it is strongly recommended, while MPN is mandatory when a product has no manufacturer-assigned GTIN. For an agent, GTIN is the most reliable way to tell that two stores sell the same product, so fill it in wherever it exists.

Is a feed enough for an agent to sell a product?

No. The feed covers search and comparison; placing the order is a separate integration: ACP for ChatGPT, UCP for Google, YCP for Yandex, the dominant search engine in Russia. In OpenAI's specification checkout is enabled separately, and at Google only products with the native_commerce attribute from onboarded merchants get the Buy button.
