Estimate the required fee for an asset

Gets the estimated required fee for an asset. Fireblocks fetches, calculates and caches the result every 30 seconds. Customers should query this API while taking the caching interval into consideration. Notes:

The networkFee parameter is the gasPrice with a given delta added, multiplied by the gasLimit plus the delta. - The estimation provided depends on the asset type.
- For UTXO-based assets, the response contains the feePerByte parameter
- For ETH-based and all EVM based assets, the response will contain gasPrice parameter. This is calculated by adding the baseFee to the actualPriority based on the latest 12 blocks. The response for ETH-based contains the baseFee, gasPrice, and priorityFee parameters.
- For ADA-based assets, the response will contain the parameter networkFee and feePerByte parameters.
- For XRP and XLM, the response will contain the transaction fee.
- For other assets, the response will contain the networkFee parameter.

Create a payout instruction set**Note:** The reference content in this section documents the Payments Engine endpoint. The Payments Engine endpoints include APIs available only for customers with Payments Engine enabled on their accounts. These endpoints are currently in beta and might be subject to changes. If you want to learn more about Fireblocks Payments Engine, please contact your Fireblocks Customer Success Manager or email CSM@fireblocks.com. **Create a payout instruction set.** A payout instruction set is a set of instructions for distributing payments from a single payment account to a list of payee accounts. The instruction set defines: - the payment account and its account type (vault, exchange, or fiat). - the account type (vault account, exchange account, whitelisted address, network connection, fiat account, or merchant account), the amount, and the asset of payment for each payee account. Learn more about Fireblocks Payments - Payouts in the following [guide](https://developers.fireblocks.com/docs/create-payouts). Endpoint Permission: Admin, Non-Signing Admin.
