Authentication

Required Header

Header	Required	Description
X-Square-OpenAPI-Key	Yes	API key for Square posting

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
- Do NOT auto-add hashtags (#xxx) during optimization — keep any hashtags the user wrote, but never add new ones
- 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
