# Delete Index

<Warning>This action is irreversible. All items, vectors and metadata will be permanently lost.</Warning>

Permanently delete an index and all its data.

## Authentication

Required - API key via `X-API-Key` header:

```http theme={null}
X-API-Key: cyborg_your_api_key_here
```

You can get an API key from the [CyborgDB Admin Dashboard](https://cyborgdb.co). For more info, follow [this guide](../../../intro/get-api-key).

## Request Body

```json theme={null}
{
  "index_name": "my_index",
  "index_key": "64_character_hex_string_representing_32_bytes"
}
```

<Expandable title="parameters">
  <ParamField body="index_name" type="string" required="true">
    Name of the index to delete
  </ParamField>

  <ParamField body="index_key" type="string">
    32-byte encryption key as a hex string. Required for indexes created with the SDK-supplied KEK path; omit for KMS-backed indexes (the service resolves the key via the stored KMSBlob).
  </ParamField>
</Expandable>

## Response

```json theme={null}
{
  "status": "success",
  "message": "Index 'my_index' deleted successfully"
}
```

## Exceptions

* `401`: Authentication failed (invalid API key) **or** wrong `index_key` on SDK-supplied indexes — see [error model](../introduction#error-model-api-keys-index-keys-and-kms)
* `404`: Index not found
* `422`: Invalid request parameters
* `500`: Internal server error

## Example Usage

```bash theme={null}
curl -X POST "http://localhost:8000/v1/indexes/delete" \
     -H "X-API-Key: cyborg_your_api_key_here" \
     -H "Content-Type: application/json" \
     -d '{
       "index_name": "my_index",
       "index_key": "your_64_character_hex_key_here"
     }'
```

## Confirmation Example

```bash theme={null}
# First, list indexes to confirm the target index exists
curl -X GET "http://localhost:8000/v1/indexes/list" \
     -H "X-API-Key: cyborg_your_api_key_here"

# Then delete the specific index
curl -X POST "http://localhost:8000/v1/indexes/delete" \
     -H "X-API-Key: cyborg_your_api_key_here" \
     -H "Content-Type: application/json" \
     -d '{
       "index_name": "old_index",
       "index_key": "your_64_character_hex_key_here"
     }'

# Verify deletion by listing indexes again
curl -X GET "http://localhost:8000/v1/indexes/list" \
     -H "X-API-Key: cyborg_your_api_key_here"
```

## Data Removal

When an index is deleted, the following data is permanently removed:

* **Index structure**: All index files and metadata
* **Vector embeddings**: All stored vector data
* **Item contents**: All associated content data
* **Metadata**: All key-value metadata pairs
* **Training data**: Any cached training information

## Use Cases

* **Cleanup**: Remove outdated or test indexes
* **Resource management**: Free up storage and memory
* **Development lifecycle**: Clean up development environments
* **Data governance**: Remove indexes containing deprecated data
