How this service works
Lists a wallet's active token approvals — which contracts can spend its tokens, the allowance, USD value at risk and a risk factor (revoke.cash-style). Essential wallet-security check for agents and users.
Output
Returns a list of active token approvals for the wallet, including: the approved spender contract address, the token being approved, the allowance amount (exact or unlimited), the USD value at risk, and a risk factor score (revoke.cash-style) indicating how dangerous each approval is.
Example use cases
Wallet security audit before trading
“I'm about to connect my wallet to a new DeFi protocol. Can you pull up all my current token approvals and show me which contracts can already spend my tokens? I want to see how much value is exposed and if anything looks risky before I approve anything new.”
Identify and revoke dangerous approvals
“I haven't used some of my older DeFi apps in months. Can you show me all the token approvals I've granted and highlight which ones have the highest risk scores? I want to know what's actually dangerous so I can revoke the sketchy ones.”
Compliance check for inherited wallet
“I just took over managing a family member's crypto wallet. Can you give me a complete list of all active token approvals on their account? I need to see everything that has access to their tokens and the dollar amounts at risk so I can clean up any suspicious approvals.”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/token-approvalsWhen to prefer
Use this endpoint when you need a comprehensive security audit of a wallet's token approvals on Base, particularly when the user wants to know which contracts can spend their tokens and how much USD value is exposed. Prefer this over the sibling 'ranked approvals' endpoint when you want the full flat list rather than a prioritized risk ranking.
Side effects
- Invalid or malformed wallet address returns an error
- Wallet with no approvals returns an empty list
- Network timeout if Base RPC is congested
- Non-checksummed address may be rejected
- Address with very large number of approvals may have partial results
