# Delete a biolink

> Permanently delete one bio page.

Delete one biolink by its public `biq_bio_...` ID. The key needs
**Biolinks: Write** with the `biolinks.delete` permission.

```bash theme={null}
curl --request DELETE \
  --url https://biq.li/api/v1/bio/biq_bio_01M19R8Q6G4S2PT7VNZ5K0W3CX \
  --header 'Authorization: Bearer biqli_your_workspace_api_key' \
  --header 'Accept: application/json'
```

The endpoint accepts no query parameters and no request body.

## Successful response

Success returns `204 No Content` with an empty response body. This is the
standard HTTP response for a completed deletion when there is no resource left
to return.

```http theme={null}
HTTP/1.1 204 No Content
```

Deleting a biolink removes the page, its page-owned widgets, and its page
associations. It does **not** delete reusable workspace links that were shown on
that page.

<Warning>
  Treat deletion as permanent through the public API. Retrieve the biolink
  first if your integration needs to save its current settings for an audit or
  confirmation screen.
</Warning>

Calling DELETE again with the same ID returns `404 resource_not_found`. The
endpoint is therefore safe in outcome, but it does not return `204` for an
already-missing resource.

## Errors

| HTTP status | Error code            | Meaning                                                                         |
| ----------- | --------------------- | ------------------------------------------------------------------------------- |
| `401`       | `invalid_token`       | The API key is missing, invalid, or revoked.                                    |
| `403`       | `insufficient_scope`  | The key lacks `biolinks.delete`, or its user cannot delete the page.            |
| `404`       | `resource_not_found`  | The ID is malformed, missing, already deleted, or belongs to another workspace. |
| `429`       | `rate_limit_exceeded` | The workspace exceeded its API request limit.                                   |

## Shared API behavior

Authentication is workspace-scoped; see [Authentication](/docs/api-reference/authentication). Errors use the standard envelope and request IDs described in [Errors](/docs/api-reference/errors), and requests are subject to [Rate limits](/docs/api-reference/rate-limits).
