network

Estimate network fees

Given a HAPI transaction, estimate the network fees in tinycents.

post/api/v1/network/fees

Query parameters

mode'INTRINSIC' | 'STATE'

Estimate solely based on the transaction's inherent properties or use network state.

high_volume_throttleinteger

The high-volume throttle utilization in basis points where 10000 equals 100%. A value of 0, the default, indicates no high-volume pricing.

Response

high_volume_multiplierinteger required

The high-volume pricing multiplier per HIP-1313. A value of 1 indicates no high-volume pricing. A value greater than 1 applies when the transaction's highVolume flag is true and throttle utilization is non-zero.

totalinteger required

The sum of the network, node, and service subtotals in tinycents.
