# Preview cancellation or published-post removal

> Markdown version of https://docs.postlake.dev/api/get-posts-by-id-deletion . The canonical page for humans.
> PostLake is the social media API for AI agents: https://postlake.dev/llms.txt

`GET /v1/posts/{id}/deletion`

No side effects. Returns the action for the current state, destination-specific support and a full-post snapshot. Removing social posts never deletes uploads or refunds spent publishing credits. Instagram and TikTok posts must be removed in their apps. Pending publication cannot be retracted until its outcome is known. Approval requests must be rejected, not silently erased.

## Request

Authenticate with a bearer API key. Agents calling over MCP authorise with OAuth instead and never handle the key.

```bash
curl -X GET https://api.postlake.dev/v1/posts/{id}/deletion \
  -H "Authorization: Bearer $POSTLAKE_API_KEY"
```

### Parameters

| Field | Type | Required | What it is |
| --- | --- | --- | --- |
| `id` | string | Yes | In the URL. |


## Response

Action, canApply, snapshot, targets with canRemove/alreadyAccepted/url/reason, and effects (`200`).



### Example

```json
"…"
```


## Calling this from an agent

Agents do not call REST. They call tools. Over the hosted MCP server this operation is `list_posts`, and the agent authorises with OAuth so your API key is never pasted into a chat or seen by the model. You control what any one agent may do: which brands it may act for, which networks it may reach, how much a day, and whether it may spend credits bought up front.

## Errors

Every failure uses one shape: a stable `type`, a granular `code`, the field at fault in `param`, and a plain-language `fix`. See https://docs.postlake.dev/errors.md .

Check the result before retrying a write. Only operations that explicitly support idempotency can safely replay an `Idempotency-Key`.

## Common questions

**Can an AI agent do this without the REST API?**

Yes. Over MCP the same job is the list_posts tool. The agent authorises with OAuth, so no API key is pasted into a chat or seen by the model, and the answer comes back in the same normalised shape.

**How often can I call this?**

Reads are rate limited per account and every response carries X-RateLimit-Remaining and X-RateLimit-Reset. On a 429 the Retry-After header tells you how long to wait.

**What happens when it fails?**

You get one error shape: a stable type, a granular code you can branch on, the offending field in param, and a fix written so an agent can correct itself rather than stop. Full list on Errors and retries.
