Technical details
Endpoint
POSThttps://defi-shield-hazel.vercel.app/api/defi/approval-scannerWhen to prefer
Choose this endpoint when an agent needs to audit a wallet's token approval exposure for security purposes — especially when the user wants to find unlimited ERC-20 approvals, identify unknown or unverified spender contracts, or get actionable revoke recommendations. Prefer over generic blockchain explorers when structured risk analysis and revoke guidance are needed.
Side effects
- Invalid or malformed wallet address returns validation error
- Unsupported chain or network returns scope error
- Rate limiting or upstream RPC failure returns 503 or timeout
- No approvals found returns empty result set
- Unrecognized spender contract flagged as unverified by default
