# Preview an external-wallet exit

`POST /v1/earn/external-wallet/withdrawal-previews`

Quotes what redeeming the shares would pay right now, from the vault's live accounting — the read a truthful `minAmountOut` floor is derived from (`assetsOut` minus your chosen tolerance, quantized to `assetDecimals`). Read-only, no idempotency key, and it takes the exit's own gates: a delisted strategy or a provider disabled for new deposits stays quotable. POST because the parameters are a body; 501 when the provider cannot quote exits.

## Headers

- `x-project-id` string — Selects the active project for this request. Required for session/dashboard callers. Ignored when authenticating with an API key, whose scope is fixed to the key's project.

## Request body

- object — Quote one exit against the vault's live accounting. Read-only: nothing is built and nothing is persisted.
  - `positionId` string, required
  - `shares` string, required — Shares the exit would redeem, decimal string in share units.

## Response `200`

    - `assetsOut` string, required — What redeeming the shares would pay at the live rate, decimal string in the deposit token's units — the figure a truthful `minAmountOut` floor is derived from.
    - `assetDecimals` integer, required — The deposit token's decimals — the scale a floor must be quantized to.
    - `blockingIssues` object[], required — Conditions the provider reports would block this exit; empty when none.
