API Endpoint: POST https://aipuejhjwmabtobjrqdz.supabase.co/functions/v1/storyclaw-api

Phase 1: API Key Check & Account Binding Confirmation

Step 1: Check API Key

First, check if STORYCLAW_API_KEY is available in the environment variable.

• Available → Use it directly, proceed to Step 2
• Not available → Ask the user: "To get started, I need your StoryClaw API Key. Please go to https://storyclaw.com/profile → StoryClaw API Key, copy it and paste it here."

Once the key is obtained (from env or user input), call get_social_status to verify:

{ "storyclaw_api_key": "<STORYCLAW_API_KEY>", "action": "get_social_status" }

• 401 Invalid API key → Tell the user: "Your API Key appears to be invalid. Please go to https://storyclaw.com/profile → StoryClaw API Key to check and recopy it."
• Success → Record connected platforms, proceed to Step 2

Step 2: Confirm Social Account Binding

Show the user their connected platforms returned by get_social_status.

If no platforms are connected, or the user asks how to link social accounts, guide them:

"Please go to https://storyclaw.com/profile → Social Account Binding, and follow the instructions to link your TikTok, Instagram, or other accounts. Come back once done."

If at least one platform is connected → proceed to Phase 2.

Only connected platforms appear as options throughout all operations.

Phase 2: Select Feature

Ask what the user needs:

Feature 1: Publish Post

Collect Content

Ask what the user wants to post. If they provide a draft or idea, enter the content optimization flow.

Content Optimization (if needed)

Ask preferences:

• Platform style: Adapt per platform (TikTok: energetic short sentences, LinkedIn: professional, X: concise, etc.)
• Tone: Professional / Casual & Humorous / Inspirational / Educational
• Hashtags: Yes / No / Auto-recommend
• Language: Chinese / English / Other

Show optimized content for user confirmation before proceeding.

Select Platforms

Show only connected platforms from get_social_status (multi-select):

Your connected platforms:
- TikTok ✅
- Instagram ✅
- Facebook ✅
...
Which platforms would you like to post to?

Restriction: If no video content → remove TikTok from options:

"TikTok requires video content. Since no video is included, TikTok has been removed from the options."

Media Attachments (Optional)

Ask if the user has images or videos to attach. publish_post only accepts HTTPS URLs — no local files.

If user has a local file → must upload first:

curl -X POST https://aipuejhjwmabtobjrqdz.supabase.co/functions/v1/storyclaw-api \
  -F "action=upload_file" \
  -F "storyclaw_api_key=<key>" \
  -F "file=@/path/to/photo.jpg" \
  -F "folder=my-media"

Upload returns an S3 HTTPS URL → use as mediaUrls.

Flow: Local file → upload_file → S3 URL → mediaUrls → publish_post

⚠️ Pre-Post Media Validation (MANDATORY)

Before calling the API, check every target platform against the limits below:

If any violation found → BLOCK and notify:

"⚠️ Cannot post: [Platform] requires [requirement], but your [media] [issue]. Please fix and retry."

Examples:

• "⚠️ Cannot post: TikTok does not support PNG images. Please convert to JPG or WebP."
• "⚠️ Cannot post: X/Twitter video duration is 145s, exceeding the 140s limit."
• "⚠️ Cannot post: Reddit does not support video. Please remove the video or deselect Reddit."
• "⚠️ Cannot post: Telegram image size is 8MB, exceeding the 5MB limit."

Files over 50MB → suggest using scheduleDate for async processing.
