# Broker an NFT Sale Using Python

Earlier examples showed how to make buy and sell offers directly between two accounts. Another option is to use a third account as a broker for the sale. The broker acts on behalf of the NFT owner. The seller creates an offer with the broker account as its destination. The broker gathers and evaluates buy offers and chooses which one to accept, adding an agreed-upon fee for arranging the sale. When the broker account accepts a sell offer with a buy offer, the funds and ownership of the NFT are transferred simultaneously, completing the deal. This allows an account to act as a marketplace or personal agent for NFT creators and traders.

# Usage

This example shows how to:

1. Create a brokered sell offer.
2. Get a list of offers for the brokered item.
3. Broker a sale between two different accounts.

1. Use the Standby account to create an NFT Sell Offer with the Broker account as the destination.
  1. Enter the **Amount** of the sell offer in drops (millionths of an XRP).
  2. Enter the **NFT ID** of the NFT you want to sell.
  3. Optionally, enter a number of seconds until **Expiration**.
  4. Enter the Broker account number as the **Destination**.
  5. Click **Create Sell Offer**.
  6. Click **Get Offers** to see the new offer.

1. Use the Operational account to create a NFT Buy Offer.
  1. Enter the **Amount** of your offer.
  2. Enter the **NFT ID**.
  3. Enter the owner’s account string in the **Owner** field.
  4. Optionally enter the number of seconds until **Expiration**.
  5. Click **Create Buy Offer**.

## Get Offers

1. Enter the **NFT ID**.
2. Click **Get Offers**.


[![Get Offers](/assets/quickstart-py27.102e8e8d0cd5499bc8a60ee385069db6fbcc89439e7476471e2938d14ca49721.ac57e6ef.png)](/assets/quickstart-py27.102e8e8d0cd5499bc8a60ee385069db6fbcc89439e7476471e2938d14ca49721.ac57e6ef.png)

## Broker the Sale

1. Copy the *nft_offer_index* of the sell offer and paste it in the **Sell NFT Offer Index** field.
2. Copy the *nft_offer_index* of the buy offer and paste it in the **Buy NFT Offer Index** field.
3. Enter a **Broker Fee**, in drops.
4. Click **Broker Sale**.

## Cancel Offer

After accepting a buy offer, a best practice for the broker is to cancel all other offers, if the broker has permissions to do so. Use **Get Offers** to get the full list of buy offers. To cancel an offer:

1. Enter the *nft_offer_index* of the buy offer you want to cancel in the **Buy NFT Offer Index** field.
2. Click **Cancel Offer**.

# Code Walkthrough

You can download the [Quickstart Samples](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/quickstart/py/) archive to examine the code samples.

## ripplex5-broker-nfts.js

Four of the five buttons for the Broker are supported by existing methods. The only new method required is the Broker Sale method.

Import dependencies and create a global variable for `testnet_url`.


```python
import xrpl
from xrpl.clients import JsonRpcClient
from xrpl.wallet import Wallet
testnet_url = "https://s.altnet.rippletest.net:51234"
```

## Broker Sale

Pass the *seed*, *sell___offer___index*, *buy___offer___index*, and *broker___fee*.


```python
def broker_sale(seed, sell_offer_index, buy_offer_index, broker_fee):
    """broker_sale"""
```

Get the broker wallet and establish a client connection.


```python
    broker_wallet=Wallet.from_seed(seed)
    client=JsonRpcClient(testnet_url)
```

Define the accept offer transaction, matching a sell offer with the selected buy offer.


```python
    accept_offer_tx=xrpl.models.transactions.NFTokenAcceptOffer(
       account=broker_wallet.classic_address,
       nftoken_sell_offer=sell_offer_index,
       nftoken_buy_offer=buy_offer_index,
       nftoken_broker_fee=broker_fee
    )
```

Submit the transaction and report the results.


```python
    reply=""
    try:
        response=xrpl.transaction.submit_and_wait(accept_offer_tx,client,broker_wallet)
        reply=response.result
    except xrpl.transaction.XRPLReliableSubmissionException as e:
        reply=f"Submit failed: {e}"
    return reply
```

## lesson5-broker-nfts.py

Revise the form from lesson 4 to add a new Broker section at the top. Changes are highlighted below.


```python
import tkinter as tk
import xrpl
import json
```

Import the `broker_sale` method.


```python
from mod1 import get_account, get_account_info, send_xrp
from mod2 import (
    create_trust_line,
    send_currency,
    get_balance,
    configure_account,
)
from mod3 import (
    mint_token,
    get_tokens,
    burn_token,
)
from mod4 import (
    create_sell_offer,
    create_buy_offer,
    get_offers,
    cancel_offer,
    accept_sell_offer,
    accept_buy_offer,
)
from mod5 import broker_sale

Add a new frame to hold the broker fields and buttons.
