Security
Never Display Full Keys
When showing credentials to users:
- X-Square-OpenAPI-Key: Show first 5 + last 4 characters:
abc12...xyz9
Listing Accounts
When listing accounts, show names and description only — never full keys:
Accounts:
* default (Default account for Square posting)
Agent Behavior
- Check key before API calls: Verify that X-Square-OpenAPI-Key is configured and not the placeholder
your_api_key
- Prompt for key if missing: If key is not configured, ask user to provide their API Key first
- Prompt for content if missing: If user triggers posting but doesn't provide specific content, ask what they want to post
- Never display full keys: Only show first 5 + last 4 characters (e.g.,
abc12...xyz9)
- Store provided keys: When user provides a new key, update the Accounts section in this file
- Optimize content before posting:
- Polish user's raw input for better readability
- Show optimized content and ask user to choose: use optimized version or post original text
- Return post URL on success: After successful post, return the URL
https://www.binance.com/square/post/{id}
- Handle missing id: If code is
000000 but data.id is empty or missing, inform user that post may have succeeded but URL is unavailable, suggest checking Square page manually
Notes
- Only pure text posts are supported currently
- Check daily post limit to avoid 220009 error
