An LLM can't know current DNS; this does the live lookup.

Explain why a payout is less than sales: walk gross -> deductions -> expected, and (if actual_deposit given) flag the unexplained gap (shortfall/surplus).

Returns what the buyer pays, what Stripe takes, what the platform nets (its application fee), and what the connected seller nets — plus the platform's effective take rate. fee_bearer: 'seller' | 'platform' | 'buyer' (who absorbs the Stripe processing fee). Rates are editable; defaults are US card standard 2.9%+$0.30.
