How this service works
Pay-per-call crypto token risk intelligence over x402 on Base mainnet. Given a contract address or symbol, returns a 0-100 risk score with A-F grade, market data (liquidity, age), and contract security flags (honeypot, hidden owner, mintable, taxes, holder concentration). $0.005 USDC per call, no signup, no API key. Not financial advice.
Output
Returns a JSON object with a numeric risk score (0-100), letter grade (A-F), plain-English verdict (e.g. 'moderate risk'), a list of human-readable risk reasons, market data (chain, liquidity in USD, age in days), and security flags (honeypot boolean, mintable boolean, hiddenOwner boolean)
Example use cases
Pre-investment token safety check
“Before I buy any of this token, can you check whether 0x2091125bFE4259b2CfA889165Beb6290d0Df5DeA on Base is a honeypot, what the risk grade is, and how concentrated the holders are?”
DeFi bot rugpull filter
“For each new token launched on Arbitrum today, run a risk check and filter out any with a risk score above 70 or honeypot flagged as true — I only want the ones that pass.”
Portfolio token audit
“I hold PEPE on Ethereum — can you pull up its risk score, liquidity, and whether the contract has any mintable or hidden owner flags so I can decide if it's still safe to hold?”
Technical details
Endpoint
GEThttps://token-risk-api-topaz.vercel.app/v1/risk?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need a quick, structured, pay-per-call risk intelligence snapshot for a specific crypto token without setting up an account or API key. It is especially useful for DeFi agents that need to screen tokens at the point of a trade or alert, or for portfolio monitoring workflows that require on-demand security checks across multiple chains including Base, Ethereum, BSC, Polygon, Arbitrum, Optimism, Avalanche, and Solana.
Side effects
- Unknown or unrecognized contract address returns an error or null result
- Token symbol ambiguity when the same symbol exists on multiple chains without a chain hint
- Unsupported chain returns a validation error
- Newly deployed contracts with no on-chain history may produce incomplete market data
- Rate-limited or payment failure via x402 returns a 402 Payment Required response
