# Multilateral FX Netting Calculator

`POST /v1/tools/compute_fx_netting_positions`

## Request

- URL: `https://ainumbers.co/v1/tools/compute_fx_netting_positions`
- Auth: none declared

Multilateral FX netting across up to 8 currencies: nets each currency's payable/receivable exposures in FCY, converts to USD at a caller-supplied spot-plus-forward-points effective rate, and returns gross volume, net volume, netting efficiency, estimated settlement savings, and per-currency residual position with an approximate 95%-confidence VaR. Ports the calculation from tools/105-fx-netting-simulator.html into a provable kernel. Spot rates, forward points, and 30-day volatility are caller-supplied reference data, never vendored.
