Buying Runes

The SDK supports automatic assembly of purchase transactions, allowing you to obtain the transaction hash (txHash) and network fee. Here's how you can use it:

const buyRunes = async () => {
  const { txHash, networkFee } = await sdk.buy({
     orderIds: [orderId1, orderId2],  // OKX Runes order IDs, you can get orderId by sdk.api.getOrders()
     paymentUtxos: [{                 // UTXOs for transaction assembly
       "txid": "ca79143aea5e22f6cfe8d57c5af6be39fecc7afd5ee931a2060f3fef8754ee15",
       "vout": 3,
       "value": 175136,
     }],
     networkFeeRate: 5,  // Desired network fee rate
   });
}
await buyRunes();

Parameter Details:

| Field Name | Type | Required | Description | | -------------- | ------ | -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | orderIds | Array | Yes | Unique identifiers for the Runes tokens | | paymentUtxos | Array | Yes | UTXOs used to assemble the purchase transaction. Ensure they contain no other assets and that the total amount covers the order and network fees.You can get your address utxo from here | | networkFeeRate | Number | Yes | The desired network fee rate. |

API

The SDK provides several APIs to query transaction-related information. For detailed parameter usage, please refer to the Runes API.

getOrders

Retrieve orders from the OKX marketplace using this API. The detailed response interface can be found in Runes API. Here's demo:

import { ORDERS_SORT_RULES } from '@okxweb3/marketplace-runes'

const requestApi = async () => {
  const data = await sdk.api.getOrders({
    runesId: '840000:3',  // Desired Runes ID
    sortBy: ORDERS_SORT_RULES.UNIT_PRICE_ASC  // Sorting rule
  });

  // data structure demo, you can get orderId

  // {
  //     "cursor": "1",
  //     "items": [
  //         {
  //           "amount": "889806",
  //           "orderId": 201268,
  //           "ticker": "DOG•GO•TO•THE•MOON",
  //           "tickerId": "840000:3",
  //           "totalPrice": {
  //               "price": "0.05472306",
  //               "satPrice": "5472306",
  //           },
  //           "unitPrice": {
  //               "price": "0.0000000615",
  //               "satPrice": "6.15",
  //           },
  //         }
  //     ]
  //   }

}
await requestApi();

Parameter Details:

| Field Name | Type | Required | Description | | ---------- | ------ | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | runesId | String | Yes | Unique identifier for the Runes token | | cursor | String | No | Cursor for retrieving order sequence numbers (max 1000) | | limit | Number | No | Page size, default 10, max 100. Specifies the maximum number of orders returned. | | sortBy | String | No | Sorting rule, default is ascending by unit price.Options include: unitPriceAsc, unitPriceDesc, totalPriceAsc, totalPriceDesc, listedTimeAsc, listedTimeDesc.  You can importORDERS_SORT_RULES from @okxweb3/marketplace-runes and use it. |

getSellersPsbt

Use this API to obtain seller PSBTs for OKX marketplace orders. Note that the PSBTs do not include the seller's signature. The detailed response interface can be found in Runes API. Here's demo:

const requestApi = async () => {
  // you can get orderId by sdk.api.getOrders()
  const data = await sdk.api.getSellersPsbt([orderId1, orderId2]);

  // data structure demo, you can get seller PSBT from sellerPSBT

  // {
  //   "orderInfos":[
  //     {
  //       "orderId": 11111,
  //       "sellerPSBT": "cHNidP8BAPW+W04EtAAAAAA="，
  //       "orderSource": 34,   //34 - OKX  82-Xverse
  //       "makerFeeAddress": "feeAddress", //platform makerFee address
  //       "makerFee": "0.003", // 0.003 BTC
  //       "takerFeeAddress": "feeAddress", //platform takerFee address
  //       "takerFee": "0.003", // 0.003 BTC
  //     }
  //   ],
  // }

}
await requestApi();

Parameter Details:

| Field Name | Type | Required | Description | | ---------- | ----- | -------- | ----------- | | orderIds | Array | Yes | Order IDs |

sendTransactions

Broadcast Runes purchase transactions with this API to obtain the transaction hash (txHash). The detailed response interface can be found in Runes API. Here's demo:

const requestApi = async () => {
  const data = await sdk.api.sendTransations({ 
    buyerPSBT: psbt, 
    fromAddress: address, 
    orderIds 
  });
  // data structure demo, you can get buy transation txHash

  // {

  // }
}
await requestApi();

Parameter Details:

| Field Name | Type | Required | Description | | ----------- | ------ | -------- | ----------------------------------------------------------------------------------------------------------- | | fromAddress | String | Yes | Buyer's payment address | | orderIds | Array | Yes | IDs of the orders to purchase | | buyerPSBT | String | Yes | Signed buyer PSBT, must be in base64 format, and assembled according to the specified transaction structure |

Middleware

Middleware allows you to access wallet addresses derived from the private key and public key for transaction assembly. It also provides pre-purchase parameters and post-purchase results, enabling actions throughout the purchase lifecycle.

import { OkxRunesSDK } from '@okxweb3/marketplace-runes'

const sdk = new OkxRunesSDK()

// Register middleware
sdk.use(async (ctx, next) => {
  console.log(`Calling ${ctx.type} with params: `, ctx)
  await next()
  console.log(`Result of ${ctx.type}: `, ctx)
})
