# Wallet Balance Checker
Check balances across Coinbase, Polymarket, Kalshi, and sportsbook accounts. Unified capital view. Read-only.
## When to Use
Use this skill when the user asks about:
- Current balances on any platform
- Total available capital across platforms
- Whether they have enough funds for a trade
- Capital allocation or distribution
- Low-balance warnings or alerts
- "How much do I have?"
## CRITICAL: Read-Only Skill
This skill ONLY reads balances. It NEVER:
- Initiates transfers or withdrawals
- Places trades or orders
- Modifies account settings
- Sends funds to any address
If the user asks to move funds, tell them to do it manually or use a dedicated transfer skill with proper security controls.
## Operations
### 1. Check Coinbase Balance
Query all Coinbase accounts and show non-zero balances:
```bash
CB_TIMESTAMP=$(date +%s)
CB_MESSAGE="${CB_TIMESTAMP}GET/v2/accounts"
CB_SIGNATURE=$(echo -n "$CB_MESSAGE" | openssl dgst -sha256 -hmac "$COINBASE_API_SECRET" | cut -d' ' -f2)
curl -s "https://api.coinbase.com/v2/accounts" \
-H "CB-ACCESS-KEY: $COINBASE_API_KEY" \
-H "CB-ACCESS-SIGN: $CB_SIGNATURE" \
-H "CB-ACCESS-TIMESTAMP: $CB_TIMESTAMP" \
-H "CB-VERSION: 2024-01-01" \
| jq '[.data[] | select((.balance.amount | tonumber) > 0) | {
currency: .balance.currency,
amount: .balance.amount,
usd_value: .native_balance.amount
}]'
