# Listing

> How buyers see your storefront: identity from your brand domain, what you do, the marketplace switch, public distribution, and the destinations your listing reaches.

The **Listing** is what buyers see: who you are, what you sell, and where they can find you. Open it
from the seller rail, ask Semi, or call `open_page` with `page: "listing"`. It has four steps,
completed in order.

## 1. Identity

Name, logo and colors come from your **brand domain** and its `brand.json`, not from fields you type
on the listing. Set the brand domain here or with `set_storefront_operator_domain`; correct the
identity at its source rather than overriding it. Verification rules are in
[Which domain is which](/concepts/domains).

## 2. What you do

The description, buyer-visible channels and accepted countries, plus your business profile (summary,
regions, verticals, publisher domains, evidence URLs). These feed every destination below.

* `save_seller` updates the description, channels, countries, links and what your listing
  publishes about your advertising policies (`advertisingPolicyDisclosure`).
* `update_business_profile` applies a confirmed business-profile change.

## 3. Listed on the marketplace

A switch included with every account. When it's on, buyers browsing the marketplace can find your
storefront. Turning it off hides it from the marketplace ("Buyers you work with can still reach your
agent.") and stops any public listing at once; it asks you to confirm. The same switch is
`publish_discovery` with `visibility: "marketplace"` or `"private"`.

## 4. Public distribution

Serves your listing on your own domain, and unlocks the app destinations. It needs the Distribution
package on your plan and a listing already live on the marketplace.

1. Save your public listing domain; add the one CNAME record it gives you at your registrar.
2. Verify it. Verifying doesn't publish.
3. Choose **Make it public** (`publish_discovery` with `visibility: "public"`).

The steps and the scheduled re-check are in
[Which domain is which](/concepts/domains#public-listing-domain).

For an active Demo Storefront, Public distribution is optional.

## Distribution

Below the steps, **Distribution** shows the listing's **Agent URL**, **Card URL** and **MCP URL**, and
the destinations as tabs:

| Destination      | State                                                                                                                                                     |
| ---------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Listing card** | A one-page PDF (**Download listing card**). Available once the listing is live on the marketplace.                                                        |
| **ChatGPT app**  | Unlocks with Public distribution. Includes publishing the OpenAI domain-ownership token. Reads `not_registered`: you register the app in OpenAI's portal. |
| **Claude**       | Unlocks with Public distribution. Reads `not_registered`: you submit the connector to Anthropic.                                                          |
| **Slack**        | Coming soon.                                                                                                                                              |

**+ Add destination** lists Microsoft Teams, Discord and WhatsApp as early access.

### OpenAI domain token

To prove domain ownership to OpenAI, paste the token OpenAI gives you. Semicola publishes it at the
address OpenAI checks on your verified public listing domain (`update_discovery_openai_challenge`), and
`probe_discovery_openai_challenge` re-checks that the address returns exactly that token. OpenAI's
review itself happens in OpenAI's portal.

## Not available yet
