# Get wallet public key

Returns the persisted public key for an exact active walletId. walletId is required (400 without it); an API key with selected wallets gets 404 for a wallet it does not list.

`GET /v1/wallets/public-key`

Resolution is DB-backed only.

Requires an [API key](/docs/developing-with-sdp/authentication) with the `wallets.read` action.

## Query parameters

- **`walletId`** · `string` · required · min length 1 · example `privy_wallet_123`

  Provider wallet ID — the `walletId` field returned by GET /v1/wallets.

## Headers

- **`x-project-id`** · `string` · min length 1 · example `prj_example`

  Required for dashboard sessions. API keys use their assigned project.

## Responses

- **`200`** Wallet public key

  - **`publicKey`** · `string` · required · min length 32 · max length 44 · example `So11111111111111111111111111111111111111112`

    Base58-encoded Solana address.

- **`400`** Bad Request

  - **`error`** · `object` · required

    Standard error payload.

    - **`code`** · `string` · required

      Machine-readable error code.

    - **`message`** · `string` · required

      Human-readable error message.

    - **`details`** · `object`

      Optional error details for debugging.

      - **`*`** · `any`

  - **`meta`** · `object`

    - **`requestId`** · `string` · min length 1 · example `req_example`

      Request identifier for tracing.

- **`401`** Unauthorized

  Same fields as `400`.

- **`403`** Forbidden. Requires the `wallets.read` action: an API key must hold it (a module's `manage` or `execute` also covers its `read`), and a signed-in member's organization role must include it. Without it the error is INSUFFICIENT_PERMISSIONS and `error.details.action` names the action. Any other 403 names its own reason.

  Same fields as `400`.

- **`404`** Not Found

  Same fields as `400`.

- **`409`** Conflict

  Same fields as `400`.

- **`500`** Internal Server Error

  Same fields as `400`.
