ERC-20 Token Risk Screener
x402
ERC-20 Token Risk Screener is a paid API for AI agents from chain.openverbs.com, paid per call via x402, $0.006/call, status unknown (last checked 2026-10-27).
Performs deterministic on-chain risk analysis of an ERC-20 token by inspecting its bytecode and metadata, flagging dangerous capabilities like blacklist/freeze, owner mint, pausability, and upgradeable proxies with severity scores and a verdict.

Output
Returns a structured report containing each detected risk flag (e.g. blacklist/freeze, owner mint, pausable transfers, upgradeable proxy, privileged owner, missing symbol/decimals, no bytecode) along with a severity level per flag, an aggregate 0-100 risk score, and an overall verdict indicating whether the token is safe, suspicious, or high-risk.
Example use cases
DeFi token safety check before swap
“I'm about to buy some tokens at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — can you screen it for rugpull risks like owner minting, blacklists, or pausable transfers and give me a risk score?”
Wallet app token trust badge
“For the token contract 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 on Base, run a deterministic risk analysis and tell me whether it has an upgradeable proxy or any privileged owner capabilities I should warn users about.”
Automated portfolio risk monitoring
“Screen the Arbitrum token at 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 for any dangerous smart contract flags — I need the severity of each finding and the overall 0-100 risk score to decide whether to include it in my portfolio tracker.”
Technical details
Endpoint
POSThttps://chain.openverbs.com/v1/token-risk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, no-third-party risk screen of an ERC-20 token derived purely from on-chain bytecode and metadata — ideal when you distrust centralized risk databases, want reproducible results, or need to flag privileged owner capabilities (mint, blacklist, pause, upgrade) before a swap, listing, or portfolio inclusion decision. Prefer alternatives if you need off-chain social signals, liquidity analysis, or holder distribution data.
Side effects
- Invalid or non-checksummed contract address returns a validation error
- Address is an EOA (no bytecode) — flagged as missing code
- Token missing symbol or decimals on-chain — flagged as metadata risk
- Unsupported chain value returns an enum validation error
- RPC endpoint for the target chain is temporarily unavailable — automatic fallback attempted but may still fail
- Token exists on a different chain than specified — returns empty or incorrect data
