ChatGPT shopping product feed / Instant Checkout: decision gate for Cedwyn e-books

Skill for: AI visibility on the commerce side, i.e. getting our e-books shown (and maybe bought) inside ChatGPT shopping answers. Read 27 Oct 2026.

What exists (primary + practitioner)

OpenAI Commerce product feed spec (developers.openai.com, read):
Merchants upload a product file: item_id, title, description, link, image, price as "18.00 USD", availability, etc.
is_eligible_search defaults to true. is_eligible_checkout opts into Instant Checkout only when checkout is enabled for the integration.
is_digital exists ("requires setup"). Leaving it out means unspecified: "do not rely on omission for digital checkout".
Geography: "The standard OpenAI-format upload currently targets the US". target_countries currently represents US, CA and MX only, and standard uploads use ["US"] whatever the column states. Other markets only "after OpenAI confirms the integration and its allowed countries and currencies".
Eligibility "does not guarantee display".
Practitioner testimony (Rye CEO Arjun Bhargava, 5 Mar 2026, read; a vendor with an interest):
OpenAI scaled back native Instant Checkout after about 12 Shopify merchants went live, out of millions, and moved purchases to retailer apps (Instacart, Target, Expedia).
It quotes Shopify's president: the bottleneck was onboarding on the AI firms' side.
The OpenAI spokesperson quote and the "12 merchants" figure are as Rye reports them; not checked against OpenAI.
Applying needs a merchant application to OpenAI (chatgpt.com returned 403 to us; not read).

The decision rule

Not now while: we sell in GBP from a UK store, the feed targets US only, and our books are digital (needs special setup). Applying would cost hours and could show us only to US shoppers with a US-currency price we don't charge.
Do now, zero cost: make sure ChatGPT's search can read the books from our own pages. That traffic is organic, not feed-based. - Product/Book JSON-LD with price in GBP, availability and an ISBN-free identifier (see merchant-listing-structured-data-ebooks.md). - OAI-SearchBot allowed in robots.txt (check: `curl -s cedwyn.bucklerfamily.estate). - A crawlable /ebooks/ page per title with a clear description.
Re-check quarterly. Open the spec page and look for (a) GB in target_countries, (b) GBP accepted, (c) digital items documented as live. - When all three are true, draft a feed (CSV from the e-book records: item_id = slug, price "9.99 GBP", is_digital true, is_eligible_checkout false at first) as a PROPOSAL for the project lead.

How we apply it to Cedwyn

The VISIBILITY CHECK run (Mon 07:30) adds one line: "ChatGPT commerce feed: GB/GBP/digital supported? yes/no (spec URL, date read)". No application until all three flip.
The ONPAGE run makes sure of three things: each /ebooks// page carries Book + Offer JSON-LD in GBP; OAI-SearchBot isn't blocked; the price on the page matches Stripe/Gumroad exactly. AI answers quoting a stale price would also breach the DMCC pricing rules (uk-dmcc-act-urgency-reviews-price-copy.md).</li> <li>Measure: Cloudflare referrers from chatgpt.com, plus the <code>utm_source=chatgpt.com</code> that ChatGPT appends to links. Check this in the Sunday growth report: a nonzero count is the signal that commerce work would pay. (The UTM-append behaviour comes from practitioner reports; not checked today.)</li> </ul> <h2>Sources</h2> <ul> <li>developers.openai.com (read: flags, is_digital, US-only geo)</li> <li>rye.com (read;
