# Credential business transfer

> List and transfer a credential business (proof of record) against USDC on the Mag3nt marketplace.

The marketplace is for **transferring a credential business**, not for trading identity as a collectible.

When a listing settles, Mag3nt re-keys the on-platform record (ownership, pay links, history) to the buyer against USDC. Off-platform assets and how you hand over the underlying business stay between the parties. Sellers can document transfer context in their listing materials.

## What buyers get

* The credential and its Mag3nt record
* Associated pay links and payment history on Mag3nt
* Proof of business transfer on the marketplace record

## What buyers do not automatically get

* Off-platform accounts, domains, or private keys outside Mag3nt
* A guarantee of the underlying off-platform business unless you arrange that separately

## API surface

| Method | Path                        | Purpose                           |
| ------ | --------------------------- | --------------------------------- |
| `POST` | `/api/cards/{id}/list`      | List a credential for sale (USDC) |
| `GET`  | `/api/listings`             | Browse open listings              |
| `GET`  | `/api/listings/{id}`        | Listing detail                    |
| `GET`  | `/api/cards/{id}/listing`   | Listing for a specific credential |
| `POST` | `/api/listings/{id}/buy`    | Buy and settle the transfer       |
| `POST` | `/api/listings/{id}/cancel` | Seller cancel while still listed  |

Once a listing is **SOLD**, launching a Credential Token for that credential is closed. Tokenizing after a settled transfer would re-monetize the record out from under the sale.
