# DELETE /api/v1/orders

Cancel all orders

Cancel all orders.

`operationId`: `cancelAllOrdersV1` · CCXT method: `cancelAllOrders` · Rate-limit class: `trading`

> **Declared server:** `https://api.testnet.nexus.xyz`. Examples follow the OpenAPI operation, path-item, then document server precedence and append the full operation path. A declared URL is not proof of live routing; verify the target deployment before use. See [Networks](/api-reference/guides/networks.md).

**Authentication:** `hmacAuth`.

Charged to the **cancel** budget, which is separate from the order budget that submission and amend draw on (`x-nexus-rate-limit-class: trading` names the class both belong to, not the bucket). A key that has spent its entire submission allowance can still cancel: exhausting one never refuses the other. It is a separate bucket rather than an exemption, so cancelling in a tight loop can still `429` — with `bucket: cancel`, the only refusal that means your cancel channel itself is saturated. See "Rate limits" for the full model.

## Parameters

| Name        | In    | Type     | Required | Default | Description                       |
| ----------- | ----- | -------- | -------- | ------- | --------------------------------- |

## Responses

| Status | Body                                                       | Meaning                                                                                                                                                                                                                                                       |
| ------ | ---------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `200`  | array of [`Order`](/api-reference/guides/schemas.md#order) | The orders that were actually cancelled, in the `Order` shape `GET /orders` serves. A cancel-all that could not reach every market still answers 200 with only the orders it did cancel, so an empty or short array is not proof that nothing rests any more. |
| `401`  | — *(no schema declared)*                                   | —                                                                                                                                                                                                                                                             |
| `429`  | — *(no schema declared)*                                   | —                                                                                                                                                                                                                                                             |

## Example

{% tabs %}
{% tab title="cURL" %}

```bash
curl -X DELETE 'https://api.testnet.nexus.xyz/api/v1/orders' \
  -H 'X-API-Key: nx_7f3a1b...' \
  -H 'X-Timestamp: 1776033911836' \
  -H 'X-Signature: <hmac-sha256>'
```

{% endtab %}

{% tab title="Python" %}

```python
import requests

headers = {
    "X-API-Key": "nx_7f3a1b...",
    "X-Timestamp": "1776033911836",
    "X-Signature": "<hmac-sha256>"
}

response = requests.delete("https://api.testnet.nexus.xyz/api/v1/orders", headers=headers)
response.raise_for_status()
print(response.json())
```

{% endtab %}

{% tab title="TypeScript" %}

```typescript
const response = await fetch("https://api.testnet.nexus.xyz/api/v1/orders", {
  method: "DELETE",
  headers: {
    "X-API-Key": "nx_7f3a1b...",
    "X-Timestamp": "1776033911836",
    "X-Signature": "<hmac-sha256>"
  },
});
if (!response.ok) throw new Error(`${response.status} ${await response.text()}`);
console.log(await response.json());
```

{% endtab %}
{% endtabs %}

`X-Signature` is a placeholder: it is derived from this specific request. See [Authentication](/api-reference/guides/authentication.md) for the canonical string and the HMAC rule.

# 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/trading/cancel-all-orders-v1.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.
