How this service works
Token safety check before buying or interacting: given an ERC20 contract on Base, returns risk_score 0-100 and verdict. Scans bytecode for dangerous functions (mint, blacklist, pausable transfers, adjustable fees), checks ownership renounced vs active, ERC20 interface completeness, and supply concentration. Red flags surface honeypot/rug indicators. For AI trading agent pre-transaction due diligence, automated token vetting, rug-pull avoidance.
Output
Returns a risk_score between 0 and 100 and a verdict (safe/risky/dangerous), along with flags for dangerous bytecode patterns such as mint, blacklist, pausable transfers, and adjustable fees, plus ownership renouncement status and supply concentration metrics.
Example use cases
Example prompt
“Before I buy this token, can you run a safety check on the ERC20 contract at 0x4200000000000000000000000000000000000006 on Base and tell me the risk score and whether it's safe — specifically if it has mint functions, a blacklist, or if ownership is still active?”
Technical details
Endpoint
GEThttps://api.x402node.dev/wallet/token-safetyWhen to prefer
Use this endpoint when an AI trading agent or DeFi automation needs pre-transaction due diligence on an unknown ERC20 token on Base L2. Prefer this over generic contract explorers when you need a structured risk score and specific rug-pull indicators (honeypot patterns, mint authority, blacklist functions) without building your own bytecode scanner.
Side effects
- Invalid or non-existent contract address returns an error
- Contract not deployed on Base mainnet causes lookup failure
- Non-ERC20 contract address may return incomplete analysis
- Network timeout from RPC provider
- Payment failure if USDC balance insufficient for $0.10 fee
