# Get Deposit Quote

`POST /v2/deposit/quote`

Returns a deposit quote with the exchange rate, USD value, and
Strike's vault deposit address. The quote is valid until `expiration_at`.

The `deposit_address` is **Strike's vault address** — hardcoded in
backend config per chain, not caller-specified. This prevents
builders from redirecting deposits.

### Authentication

Requires API wallet authentication via headers:
- `X-API-Wallet-Public-Key`
- `X-API-Wallet-Signature`
- `X-API-Wallet-Timestamp`
- `X-API-Wallet-Nonce`

## Request body

- DepositQuoteRequest
  - `blockchain` 'ethereum' | 'solana' | 'cardano', required — Target blockchain for the deposit.
  - `asset_symbol` string, required — Asset to deposit (e.g. `USDC`, `SOL`, `ADA`).
  - `asset_amount` string, required — Amount in the asset's smallest unit (e.g. lamports for SOL, lovelace for ADA, wei for ETH). String to preserve precision.
