Blockchain Fee → Estimate Transaction Smart Fee
AI-generatedSummary
Estimates the fee rate for a UTXO transaction using its blockchain, network, confirmation target, and optional priority. Select a supported blockchain (Bitcoin, Litecoin, or Dash), choose Mainnet or Testnet, and set how many blocks the transaction should take to confirm.
Inputs
- Blockchain Type — Defaults to EVM in the UI, but this operation’s smart-fee endpoint is implemented for UTXO chains. Select UTXO to provide the blockchain and network fields.
- Blockchain (required) — Choose Bitcoin, Litecoin, or Dash. The UI description says the endpoint does not support Bitcoin Cash, Dogecoin, or Zcash.
- Network (required) — Choose Mainnet or Testnet.
- Confirmation Target (required) — Number of blocks within which the transaction should be confirmed.
- Fee Rate Priority — Economical or Conservative. The implementation sends this as the
estimateModequery parameter using lowercase values; if omitted, the API applies its default.
Output shape
a single fee estimate object
The response is unwrapped from the API’s
data.itemfield. The UI exposes Blockchain and Network only for UTXO; other Blockchain Type selections do not provide the required smart-fee fields in this operation.
