Get 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
