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:

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
  }]'
