name: blog-post
description: Public API blog posts (X-API-KEY). CRUD blog posts, AI generation (outline/full/section), AI operations (expand/shorten/rewrite), images, exports, and social-campaign-from-blog. PublicApiBlogPostController (/api/v2/blog-posts).

# Skill: Blog Posts

## Description

Manage blog posts and AI-powered writing workflows. This skill documents **PublicApiBlogPostController** at `/api/v2/blog-posts`. Authenticate with `X-API-KEY`.

Key async behaviors:

- **Outline/full/section generation** returns `activityId` → poll **`GET /api/v2/jobs/{activityId}`**.
- **Blog post “generate”** returns `aiEditLiveObjectId` → poll **`GET /api/v2/blog-posts/{blog_post_id}/generation/{ai_edit_id}`**, then **POST accept** to commit.
- **AI operations** return `aiOperationId` → poll **`GET /api/v2/blog-posts/{blog_post_id}/ai-operations/{ai_operation_id}`**, then **POST accept** to apply.
- **Exports** return `exportId` → poll **`GET /api/v2/blog-posts/{blog_post_id}/exports/{export_id}`** (not the jobs endpoint).

## Blog post CRUD

| Action | Method | Path |
|--------|--------|------|
| List (cursor) | GET | `/api/v2/blog-posts?limit=20&cursor=` |
| Get by id | GET | `/api/v2/blog-posts/{blog_post_id}` |
| Update content | PUT | `/api/v2/blog-posts/{blog_post_id}/content` |
| Update meta | PATCH | `/api/v2/blog-posts/{blog_post_id}` |
| Delete | DELETE | `/api/v2/blog-posts/{blog_post_id}` |

```bash
curl "$LAYERPROOF_BASE_URL/api/v2/blog-posts?limit=20" \
  -H "X-API-KEY: $LAYERPROOF_API_KEY"
```

---

## Generate blog post (create + AI edit)

| Action | Method | Path |
|--------|--------|------|
| Start generation | POST | `/api/v2/blog-posts/generate` |
| Poll generation | GET | `/api/v2/blog-posts/{blog_post_id}/generation/{ai_edit_id}` |
| Accept generation | POST | `/api/v2/blog-posts/{blog_post_id}/generation/{ai_edit_id}/accept` |

```bash
curl -X POST "$LAYERPROOF_BASE_URL/api/v2/blog-posts/generate" \
  -H "Content-Type: application/json" \
  -H "X-API-KEY: $LAYERPROOF_API_KEY" \
  -d '{"prompt":"Write a blog post about cursor pagination in APIs","outputLanguage":"en"}'
```

Notes:

- Use `aiEditLiveObjectId` from the response as `{ai_edit_id}`.
- When poll status returns `ACCEPTED`, call accept to commit it to the blog post.

---

## Outline + section generation (jobs)

| Action | Method | Path | Polling |
|--------|--------|------|---------|
| Generate outline | POST | `/api/v2/blog-posts/{blog_post_id}/generation/outline` | `/api/v2/jobs/{activityId}` |
| Get outline | GET | `/api/v2/blog-posts/{blog_post_id}/outline` | n/a |
| Generate full post | POST | `/api/v2/blog-posts/{blog_post_id}/generation/full-post` | `/api/v2/jobs/{activityId}` |
| Generate section content | POST | `/api/v2/blog-posts/{blog_post_id}/sections/{section_id}/generation/content` | `/api/v2/jobs/{activityId}` |
| Expand section | POST | `/api/v2/blog-posts/{blog_post_id}/sections/{section_id}/generation/expand` | `/api/v2/jobs/{activityId}` |

  -d '{"prompt":"Outline for a technical post with examples"}'

## AI operations (expand / shorten / rewrite a selection)

| Action | Method | Path |
|--------|--------|------|
| Start operation | POST | `/api/v2/blog-posts/{blog_post_id}/ai-operations` |
| Poll status | GET | `/api/v2/blog-posts/{blog_post_id}/ai-operations/{ai_operation_id}` |
| Cancel | POST | `/api/v2/blog-posts/{blog_post_id}/ai-operations/{ai_operation_id}/cancel` |
| Accept (apply) | POST | `/api/v2/blog-posts/{blog_post_id}/ai-operations/{ai_operation_id}/accept` |

Behavior details:

- `command` values: `expand`, `shorten`, `rewrite`
- Server maps `shorten` → internal `summarize`.
- Use `idempotencyKey` (`idempotency_key`) to safely retry start calls.
- Accept will return **409** if the original selection no longer exists in the current content.

```bash
curl -X POST "$LAYERPROOF_BASE_URL/api/v2/blog-posts/<blog_post_id>/ai-operations" \
  -H "Content-Type: application/json" \
  -H "X-API-KEY: $LAYERPROOF_API_KEY" \
  -d '{"command":"rewrite","selection":"<exact text to replace>","prompt":"Make it more concise","idempotency_key":"rewrite-1"}'
```

## Images

| Action | Method | Path |
|--------|--------|------|
| List resolved images | GET | `/api/v2/blog-posts/{blog_post_id}/images` |

---

## Cached content (draft autosave)

| Action | Method | Path |
|--------|--------|------|
| Save cached markdown | PUT | `/api/v2/blog-posts/{blog_post_id}/cached-content` |

Returns **204 No Content**.

```bash
curl -X PUT "$LAYERPROOF_BASE_URL/api/v2/blog-posts/<blog_post_id>/cached-content" \
  -H "Content-Type: application/json" \
  -H "X-API-KEY: $LAYERPROOF_API_KEY" \
  -d '{"markdown":"# Draft\n\nHello..."}'
```

---

## Exports (async)

| Action | Method | Path |
|--------|--------|------|

| Export Markdown | POST | `/api/v2/blog-posts/{blog_post_id}/export/markdown` |
| Export PDF | POST | `/api/v2/blog-posts/{blog_post_id}/export/pdf` |
| Poll export | GET | `/api/v2/blog-posts/{blog_post_id}/exports/{export_id}` |

```bash
curl -X POST "$LAYERPROOF_BASE_URL/api/v2/blog-posts/<blog_post_id>/export/pdf" \
  -H "X-API-KEY: $LAYERPROOF_API_KEY"
```

---

## Social campaign from blog post

| Action | Method | Path |
|--------|--------|------|
| Start campaign generation | POST | `/api/v2/blog-posts/{blog_post_id}/social-campaign` |

  -H "X-API-KEY: $LAYERPROOF_API_KEY" \
  -d '{"targetTopicCount":5,"webSearchEnabled":true}'
```

---

## Agent behavior

**Before any API call, verify environment variables are set:**

```bash
if [[ -z "${LAYERPROOF_BASE_URL}" ]]; then
  echo "ERROR: LAYERPROOF_BASE_URL is not set."
  return 1
fi
if [[ -z "${LAYERPROOF_API_KEY}" ]]; then
  echo "ERROR: LAYERPROOF_API_KEY is not set."
  return 1
fi

# Load .env.local if present
if [[ -f .env.local ]]; then
  set -a
  source .env.local
  set +a
fi
```

1. Resolve `blog_post_id` (list or create via generate).
2. For **jobs-based** endpoints (outline/full/section/expand), poll `/api/v2/jobs/{activityId}` until terminal.
3. For **generate** (ai edit) endpoints, poll `/api/v2/blog-posts/{id}/generation/{ai_edit_id}` until `ACCEPTED`, then call accept.
4. For **AI operations**, poll `/ai-operations/{ai_operation_id}` until `ACCEPTED`, then call accept.
5. For **exports**, poll `/exports/{export_id}` until `COMPLETED`, then use `downloadUrl` (presigned) before `expiresAt`.

---

## Response format (required)

- Always show the **raw JSON response** (verbatim) in a JSON code block.
- If the response contains a URL to an image (`presignedUrl`, etc), **render/show the image** and also show the JSON response (do not convert to a table).
