## Estimate Rune Mint Order - Request

You can specify the characteristics of the Runes \<int order you wish to estimate, by passing a request body, with the below properties:

<table><thead><tr><th width="226.1875">Estimate Mint - Request Body</th><th>Description</th></tr></thead><tbody><tr><td><code>runeName</code></td><td>a string representing the <a href="https://docs.ordinals.com/runes.html#name">name of the Rune </a>to mint</td></tr><tr><td><code>repeats</code></td><td>a number representing the number of mint transactions to create. Every mint transaction creates a <a href="https://docs.ordinals.com/runes.html#amount">fixed amount </a>of new units of a rune, you can use <code>repeats</code> to mint a multiple of that amount. <br><span data-gb-custom-inline data-tag="emoji" data-code="2139">ℹ️</span> Note that there is a 4000 repeat limit per order</td></tr><tr><td><code>destinationAddress</code></td><td>The Bitcoin address to which the minted runes should be allocated.<br><span data-gb-custom-inline data-tag="emoji" data-code="2139">ℹ️</span> If minting Runes for your app user, make sure to use their  taproot/ordinal addresses for runes holdings.</td></tr><tr><td><code>feeRate</code> </td><td>a number representing the desired fee rate to set for the Rune mint transaction(s), in sats per vbytes</td></tr><tr><td><code>appServiceFee</code> (<span data-gb-custom-inline data-tag="emoji" data-code="2139">ℹ️</span> optional)</td><td>a number representing the sats value of the fee to charge your user for your service. </td></tr><tr><td><code>appServiceFeeAddress</code> (<span data-gb-custom-inline data-tag="emoji" data-code="2139">ℹ️</span> optional)</td><td>a string representing the Bitcoin address which will receive the  <code>appServiceFee</code>, if a fee is specified</td></tr><tr><td><code>network</code> (<span data-gb-custom-inline data-tag="emoji" data-code="2139">ℹ️</span> optional)</td><td>a string representing the Bitcoin network to use for the mint runes transactions: <code>'Mainnet'</code> or <code>'Testnet'</code></td></tr></tbody></table>
