# DELETE /keys/{key\_id}

Delete an API key.

`operationId`: `deleteApiKey`

**Authentication:** `bearerAuth`.

Delete a key you own. Cannot delete keys owned by other wallets. Deletion is scoped to the network serving this request. A key minted on another network is invisible here and cannot be revoked here, and the `404` below does not distinguish “no such key” from “not yours” from “live on another network” — so it is never proof that a key has been retired. Revoke a key on the host that minted it, and confirm the revocation there.

## Parameters

| Name     | In   | Type     | Required | Description |
| -------- | ---- | -------- | -------- | ----------- |
| `key_id` | path | `string` | Yes      | —           |

## Responses

| Status | Body                     | Meaning                                                                                                                                                          |
| ------ | ------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `200`  | — *(no schema declared)* | Key deleted                                                                                                                                                      |
| `401`  | — *(no schema declared)* | Valid session token required                                                                                                                                     |
| `404`  | — *(no schema declared)* | Key not found on this network, or not owned by you. Not proof the key is gone: a key minted on another network is invisible here and is unaffected by this call. |

## Example

```bash
curl -X DELETE 'https://exchange.nexus.xyz/api/exchange/keys/{key_id}' \

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.nexus.xyz/api-reference/authentication/delete-api-key.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
