# Preview a direct vault deposit

`POST /v1/earn/vault-deposit-previews`

Quotes how many shares a direct vault deposit would mint from the provider's live accounting. Use it when the strategy's `depositSlippage.quoteRequired` is true, then derive `minSharesOut` from `sharesOut` minus the chosen tolerance. Read-only, no idempotency key, and 501 when the provider cannot quote deposits.

## 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 direct vault deposit against the provider's live accounting. Read-only: nothing is built and nothing is persisted.
  - `strategyId` string, required
  - `amount` string, required — Deposit amount in the vault token's units.

## Response `200`

Live deposit quote

- object — Standard success response envelope.
  - `data` object, required

    - `shareDecimals` integer, required — The share mint's decimals, which the floor must be quantized to.
    - `blockingIssues` object[], required — Conditions the provider reports would block this deposit; empty when none.
      - `code` string, required
      - `message` string, required
    - `feeSponsored` boolean, required — Whether SDP's treasury vault flow would use its configured paymaster on this cluster. Embedded Yield partners sponsor their external-wallet flow separately by passing `feePayer` to the transaction build.
