Technical details
Endpoint
POSThttps://httpay.xyz/api/approval-risk-auditorWhen to prefer
Use this endpoint when you need to audit a specific wallet's ERC20 token approval exposure on Base for security purposes — particularly to detect unlimited allowances granted to unknown or potentially malicious contracts. Prefer this over generic blockchain explorers when you want a structured, risk-scored output specifically designed for approval security review. Also useful in automated DeFi security workflows.
Side effects
- Invalid wallet address format — returns error if address is not a valid 0x... Ethereum address
- Unsupported chain parameter — returns error if chain is not supported
- No approvals found — wallet may have no outstanding ERC20 approvals to audit
- Network or RPC timeout — on-chain data fetch may fail intermittently
- Payment not received — x402 payment flow failure results in 402 response
