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=$(date +%s)
CBMESSAGE="${CBTIMESTAMP}GET/v2/accounts"
CBSIGNATURE=$(echo -n "$CBMESSAGE" | openssl dgst -sha256 -hmac "$COINBASEAPISECRET" | cut -d' ' -f2)

curl -s "https://api.coinbase.com/v2/accounts" \
-H "CB-ACCESS-KEY: $COINBASEAPIKEY" \
-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,
usdvalue: .nativebalance.amount
}]'
