Usage notes

  • Call this endpoint before initiating a payout to show customers the exact costs.
  • The feeBearer determines whether the tenant or customer absorbs transaction fees.
  • Use the includedFees array to display rail-specific fees and settlement durations.
Cache calculator responses briefly (30–60 seconds) to reduce latency while the user reviews quotes.
