Skill: Export Slides

Description

Export presentations as PNG ZIP, PPTX, or narrated video (Pro / credits). This skill documents the public API at /api/v2/projects/{projectId}/exports (PublicApiExportController). Exports are async: POST returns export_id (same id used for job-style polling); poll GET .../exports/{export_id} for status; when COMPLETED, use download_url (presigned, ~1 hour). Authenticate with X-API-KEY header.

TypeScript types (request / response)

Mirrors PublicApiExportController data classes.

// --- Export PNG / PPTX / Video (POST) — 202 ---
type PublicExportStartedResponse = {
  export_id: string;  // UUID — poll GET .../exports/{export_id}
  status?: string;   // default "PENDING"
};

// --- Video export body (POST .../exports/video) — optional ---
type PublicVideoExportRequest = {
  quality?: string | null;       // export quality enum as returned by API
  include_notes?: boolean;      // default false
  voice?: string | null;         // default "Puck"
  language_code?: string | null; // default "en-US"
};

// --- Get Export Status (GET) ---
type PublicExportProgress = { current: number; total: number };
type PublicExportStatusData = {
  export_id: string;
  status: string;
  format: string;
  download_url?: string | null;
  expires_at?: string | null;
  file_size_bytes?: number | null;
  progress?: PublicExportProgress | null;
  error_message?: string | null;
};
type PublicExportStatusResponse = { data: PublicExportStatusData };

// --- Cancel Export (POST) ---
type PublicCancelExportResponse = {
  export_id: string;
  status: string;  // "CANCELLED" or "ALREADY_TERMINAL"
};

Export PNG ZIP (async)

Response (202): PublicExportStartedResponse. Poll GET .../exports/{exportId} for status.

curl -X POST "$LAYERPROOF_BASE_URL/api/v2/projects/<project_id>/exports/png" \
  -H "X-API-KEY: $LAYERPROOF_API_KEY"

---

Export PPTX (async)

Response (202): PublicExportStartedResponse. Poll GET .../exports/{exportId} for status.

curl -X POST "$LAYERPROOF_BASE_URL/api/v2/projects/<project_id>/exports/pptx" \
  -H "X-API-KEY: $LAYERPROOF_API_KEY"

---

Export Video (async)

Narrated video with TTS. May return 402 (quota) or 403 (Pro plan required). Optional JSON body: PublicVideoExportRequest.

curl -X POST "$LAYERPROOF_BASE_URL/api/v2/projects/<project_id>/exports/video" \
  -H "Content-Type: application/json" \
  -H "X-API-KEY: $LAYERPROOF_API_KEY" \
  -d '{"include_notes":false,"voice":"Puck","language_code":"en-US"}'

---

Get Export Status

Response: PublicExportStatusResponse. When status is COMPLETED, data.downloadUrl and data.expiresAt are set.

curl "$LAYERPROOF_BASE_URL/api/v2/projects/<project_id>/exports/<export_id>" \
  -H "X-API-KEY: $LAYERPROOF_API_KEY"

---

Cancel Export

Response: PublicCancelExportResponse.

curl -X POST "$LAYERPROOF_BASE_URL/api/v2/projects/<project_id>/exports/<export_id>/cancel" \
  -H "X-API-KEY: $LAYERPROOF_API_KEY"

---

Agent behavior

When the user asks to export a project (PNG ZIP or PPTX) or check/cancel an export, do the following.

1. Choose the right endpoint

Base path: /api/v2/projects/{projectId}/exports. All require projectId.

User intent	Endpoint	Method
Export as PNG ZIP	.../exports/png	POST
Export as PPTX	.../exports/pptx	POST
Export as video (TTS)	.../exports/video	POST
Get export status / download URL	.../exports/{exportId}	GET
Cancel in-progress export	.../exports/{exportId}/cancel	POST

2. Build and run

Step 1 — Check environment variables first. Before running any curl command, verify both LAYERPROOF_BASE_URL and LAYERPROOF_API_KEY are set on the user's machine:

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

If running from a project directory with a .env.local file, load it first:

if [[ -f .env.local ]]; then
  set -a
  source .env.local
  set +a
fi

Step 2 — Auth: Include X-API-KEY: $LAYERPROOF_API_KEY. Read env vars; if missing, tell the user. Step 3 — Path: Resolve projectId from context; exportId from the 202 response of export PNG/PPTX. Step 4 — Run: Run curl and show the result.

3. After starting export

• Response contains export_id. Tell the user to poll GET .../exports/{export_id} until status is COMPLETED (or FAILED). When COMPLETED, use data.download_url (valid ~1 hour).

4. Response handling

• Always show raw JSON in a code block.
• If download_url is present, show the URL and mention the file can be downloaded.
• On 410, download URL expired; suggest triggering a new export.

5. Example workflows

Workflow A — User: "Export my project as PPTX and give me the download link."

1. Resolve projectId. POST .../projects/{projectId}/exports/pptx; capture export_id from 202 response.
2. Poll GET .../projects/{projectId}/exports/{export_id} until data.status is COMPLETED or FAILED. If FAILED, show data.error_message and suggest retry or checking project/slides.
3. When COMPLETED, show data.download_url and data.expires_at; remind user the URL is temporary (~1 hour).

Workflow B — User: "Export the same project as both PNG ZIP and PPTX; if one fails, still get the other."

1. POST .../exports/png; get export_id_png. POST .../exports/pptx; get export_id_pptx.
2. Poll both: GET .../exports/{export_id_png} and GET .../exports/{export_id_pptx} (e.g. in sequence or inform user to poll). For each: when COMPLETED, show download_url; when FAILED, show error_message and which format failed.
3. Optionally: if user wants to cancel the slower one, POST .../exports/{export_id}/cancel for the relevant export id.

Workflow C — User: "Start a PPTX export; I might cancel it if it takes too long."

1. POST .../exports/pptx; get export_id. Tell user polling has started.
2. If user says "cancel the export" before COMPLETED: POST .../exports/{export_id}/cancel; show response (status CANCELLED or ALREADY_TERMINAL).
3. If not canceled: poll until COMPLETED and show download_url, or FAILED and show error_message.

Response format (required)

• (if response contains url to show image) please show image and show json response instead of table
• Always show the raw JSON response (verbatim) in a JSON code block.
• If the response contains a URL for an image, render/show the image and also show the JSON response (do not convert to a table).
