# Fixed Price Offers (Listings)

Fixed Price Offers allow sellers to list domain names for sale at a predetermined price. Buyers can purchase these domain names by paying the specified amount.

###  Struct

```rust
pub struct FixedPriceOffer {
    /// Account tag
    pub tag: Tag,
    /// Nonce
    pub nonce: u8,
    /// Name being sold
    pub name_account: Pubkey,
    /// Offer owner
    pub owner: Pubkey,
    /// Quote token used for offer
    pub quote_mint: Pubkey,
    /// Amount of the offer
    pub offer_amount: u64,
    // Offer amount token account destination
    pub token_destination: Pubkey,
};
```

### Make Fixed Price Offer

Creating a fixed price offer is handled by the `makeFixedPriceOffer` function, as shown in the code snippet below. 

```typescript
import { NAME_OFFERS_ID, makeFixedPriceOffer } from "@bonfida/name-offers";
import { getDomainKeySync } from "@bonfida/spl-name-service";

const seller = new PublicKey("..."); // Public key of the seller i.e domain owner
const mint = new PublicKey("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"); // USDC mint
const amount = 1 * 1e6; // Amount with decimals, here 1 USDC
const { pubkey: domainKey } = getDomainKeySync("something.sol"); // Domain public key

const ix = await makeFixedPriceOffer(
  connection,
  amount,
  mint,
  seller,
  domainKey,
  NAME_OFFERS_ID 
);
```

### Buy Fixed Price Offer

Buying a fixed price offer is facilitated through the `buyFixedPrice` function, which ensures the transfer of the domain to the buyer and the payment to the seller:

```typescript
import { 
NAME_OFFERS_ID, 
buyFixedPrice, 
getFixedPriceOffersForName 
} from "@bonfida/name-offers";
import { getDomainKeySync } from "@bonfida/spl-name-service";

const buyer = new PublicKey("..."); // Public key of the offer buyer
const source = new PublicKey("..."); // Source of the funds used to purchase the offer. In case of SOL it's the same as `buyer`. If another token is used, it's the ATA of the buyer for the given mint.
const { pubkey: domainKey } = getDomainKeySync("something.sol"); // Domain public key
const referrer: PublicKey | undefined = undefined; // Optional referrer

// Util function to get fixed price offers by name, by owner, or all fixed price offers.
const fixedPriceOffers = await getFixedPriceOffersForName(
  connection,
  domainKey
);

// This example arbitrarily selects the first fixed price offer in the list. Filter offers based on the your needs.
const fixedPriceKey = fixedPriceOffers[0].pubkey;

const ix = await buyFixedPrice(
  connection,
  fixedPriceKey,
  buyer,
  source,
  NAME_OFFERS_ID,
  referrer
);
```
