Amount: "10.00"
Token: "USDC"
Recipient: "0x..."
Chain: "base"
Reason: "API credits" (optional)

check_limits

Check if a payment would be allowed before making it. Returns whether it would auto-approve or need manual approval.

How It Works

You ask Claude to pay for something
Claude uses request_payment tool
ClawVault checks your rules:
- Within rules → auto-approved, payment executes
- Outside rules → pending, you get a Telegram/dashboard notification
You approve or deny from Telegram or the web dashboard
Claude gets the result
