# Get Crypto Deposit Address by Idempotency Key

`GET /v1/customers/{customer_id}/deposit_instruction`

Look up a crypto deposit instruction using the idempotency key provided during creation.

**Use Case:** Verify if a crypto deposit instruction was successfully created when network issues or timeouts occurred during the create request.

For EVM wallets, the `network` field indicates whether it was created as a specific chain (e.g., `ETHEREUM`) or as the virtual `EVM` network.

## Path parameters

- `customer_id` string, required

## Query parameters

- `idempotency_key` string, required — HTTP `Idempotency-Key` header value. Stricter than other IDs: ≤64 ASCII chars per the common REST API convention.

## Response `200`

Successfully retrieved crypto deposit instruction

- DepositInstructionResponse — A deposit instruction representing a crypto deposit wallet.
  - `deposit_instruction_id` string, required — Unique wallet identifier assigned by the custody provider
  - `network` string, required — Network name accepted by deposit-wallet creation surfaces. Unlike [`Network`], this type intentionally accepts the virtual `EVM` network group used by Web/OpenAPI deposit-address creation.
  - `address` string, required — On-chain deposit address.
  - `is_default` boolean, required — Whether this is the default deposit wallet for the network. Each customer has exactly one default wallet per network, created automatically during onboarding; additional wallets are non-default.
  - `nickname` string, required — Human-readable label. Empty string when not set.
  - `status` 'PENDING' | 'READY' | 'FAILED', required
  - `created_at` string, required

## Other responses

- `400` — Missing or empty idempotency_key query parameter
- `401` — Unauthorized
- `404` — No crypto deposit instruction found with this idempotency key
- `405` — Method Not Allowed
- `500` — Internal Server Error
