List ordinals for sale

This endpoint is used to list one or more ordinals for sale on the marketplace. The endpoint returns a Partially Signed Bitcoin Transaction (PSBT) which the owner must sign. If someone buys the ordinal, the buyer must supply the unspent transaction output (UTXO) covering the ordinal's price and any applicable fees. The seller's signature is required only during the initial listing, while only the buyer's signature is necessary for completing the purchase. Platform Cost: A platform fee is applied only when an ordinal is sold. It is not charged for listing an ordinal. The current fee is 1% of sale amount charged to the seller.

The response from this endpoint is a PSBT, encoded in base64, which the Ordinal owner's wallet needs to sign.

Here's an example of how you can sign a listing transaction with the Xverse wallet:

      // XVerse Wallet example of creating a signing request 
      // when listing an Ordinal for sale
      const sellerInput = {
        address: ordinalsAddress, // Seller's ordinal wallet address
        signingIndexes: [0], // always [0] when listing
        // Specify sigHash type as SIGHASH_SINGLE | SIGHASH_ANYONECANPAY
        sigHash: bitcoin.Transaction.SIGHASH_SINGLE | bitcoin.Transaction.SIGHASH_ANYONECANPAY,

      // Create the listing PSBT by calling /marketplace/create-listing API
      // This returns a base64 PSBT in string format which needs to be signed
      const { data } = await axios({
        method: 'post'
        url: '',
        data: {
        headers: {
        'x-api-key': API_KEY,

      // When using XVerse Wallet
      // Create the payload for signing the seller transaction
      const payload = {
        network: { type: "Mainnet" },
        message: "Sign Seller Transaction",
        psbtBase64: data.psbt, // PSBT returned by the clear-listing API
        broadcast: false,
        inputsToSign: [sellerInput],

      // Make signing request
      await signTransaction({
        onFinish: async (response) => {
          try {
            // signed succesffully

            // Save the listing with the signed PSBT
            const updateListingData = {
              signedListingPSBT: response.psbtBase64,

            // Save the listing PSBT by calling /marketplace/save-listing API
            // This saves the signed PSBT
            const saveResponse= await axios({
              method: 'patch'
              url: '' + sellerOrdinals[0].id,
              data: {
                ordinalId: sellerOrdinals[0].id,
              headers: {
              'x-api-key': API_KEY,
          } catch (Error) {
            // error handling
        onCancel: () => { // User cancelled signing request }
