# Recompute Fund NAV

`POST /v1/tools/recompute_fund_nav`

## Request

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

Recomputes a fund's net-asset-value-per-share from SUPPLIED holdings (quantity x supplied price, multi-currency with supplied FX), accruals (income and expense with a declared day-count convention), liabilities, and shares outstanding, using fixed-point BigInt money math throughout (no float accumulation). Applies a declared rounding mode (e.g. $0.0001 for a money-market fund vs $0.01 for a standard fund) and returns a full component breakdown. HARD FENCE: every price and FX rate is supplied and asserted, never fetched (zero-egress); this recomputes the arithmetic over declared inputs and attests THAT, never a fair-value opinion, never an independent valuation, never live market data. First entry of the Funds/NAV family (nav-verification-pack) alongside test_nav_error_materiality (FN-2) and compute_fund_expense_ratios (FN-3). Not fund_share_class_composer (asset allocation) or any pricing/valuation tool. 40-Act/UCITS citations informative only.
