# Direct Indexing Fit Screen

`POST /v1/tools/compute_direct_indexing_fit_screen`

## Request

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

Computes a direct-indexing fit screen from caller-declared synthetic inputs: the net benefit in basis points is the declared expected tax alpha minus the declared fee delta (direct-indexing fee minus ETF expense ratio), rounded half-up to 2 decimal places with the arithmetic restated in a trace. The verdict reports the sign of that declared arithmetic only (FIT_POSITIVE, FIT_NEGATIVE, FIT_NEUTRAL). When the caller also declares a holding period and an alpha-exhaustion horizon, the node adds an exhaustion warning; when the caller declares a concentrated stock position, it adds an unwind note. This is a deterministic calculator over declared numbers: it is never advice, never an optimizer, and it prices no costs it has not been given. Zero storage, zero network, no runtime clock.
