Threads FastAPI skill

Use this skill whenever the user asks to generate, queue, schedule, or publish content to Threads.

Required environment variables (on the Gateway host)

• THREADS_FASTAPI_BASE_URL (example: http://127.0.0.1:8000)
• THREADS_QUEUE_SECRET (the value to send as X-Queue-Secret, only for /threads/publish)
• Optional: THREADS_TENANT_ID (default: agency_paris)

If these are missing, ask the user for the correct values.

Storage options (backend-side)

This skill does not store media itself. Storage is handled by the FastAPI backend.

Local Pack (demo / single machine)

Set on the backend:

STORAGE_PROVIDER=local
UPLOADS_DIR=uploads
UPLOADS_PATH=/uploads

This stores uploads in UPLOADS_DIR and serves them from UPLOADS_PATH.

Cloud storage (prod)

Set STORAGE_PROVIDER=cloudinary or s3 on the backend and configure the

provider credentials there.

Endpoints (per your spec)

• POST {BASE}/api/v1/threads/publish
• Requires header X-Queue-Secret
• POST {BASE}/api/v1/assistant/chat
• No queue secret header (unless your backend requires it later)

Both accept JSON.

How to call (safe)

Use the HTTP tool in OpenClaw (not exec).

Send JSON directly to the FastAPI endpoint with the required headers.

Example:

• URL: {BASE}/api/v1/threads/publish
• Method: POST
• Headers: X-Queue-Secret:
• Body: JSON payload (see below)

Payloads

A) Publish / enqueue Threads post

Call POST {BASE}/api/v1/threads/publish with:

{
  "message": "<message text>",
  "images": [],
  "scheduled_at": null,
  "publish_mode": "queue",
  "auto_proxy_images": true,
  "meta": {
    "tenant_id": "agency_paris",
    "source": "telegram",
    "chat_id": "<tg chat id>",
    "user_id": "<tg user id>",
    "username": "<tg username>"
  }
}

B) /postimg generate+enqueue via assistant

Call POST {BASE}/api/v1/assistant/chat with:

{
  "session_id": "tg_<chat id>",
  "execute_tools": true,
  "message": "Generate and enqueue one image post",
  "context": {
    "tenant_id": "agency_paris",
    "prompt": "<tg args>",
    "message": "<tg args>",
    "provider": "replicate",
    "model": "black-forest-labs/flux-1.1-pro",
    "source": "telegram",
    "campaign": "remote_demo",
    "api_base_url": "http://127.0.0.1:8000"
  }
}

Note: The skill should fill tenant_id from THREADS_TENANT_ID when set.

Safety

• Never forward secrets from chat into shell commands except as the -QueueSecret argument.
• Do not log the secret.
• Validate that BaseUrl is an http(s) URL.
