How this service works
Pay-per-call crypto microdata for trading/onchain AI agents via x402 (USDC on Base): Base gas, token risk, balances, multi-venue prices, Hyperliquid book/funding, kimchi premium. No API keys.
Output
A JSON object with: chain ('base'), token symbol and decimals, holder count, risk_score (0–100 int), risk_level ('low'/'medium'/'high'), verdict ('OK' or flagged), can_sell and should_buy booleans, flags array (e.g. 'upgradeable_proxy'), reasons array explaining flags, honeypot simulation result, buy/sell tax rates, top-10 holder percentage, and contract metadata (is_contract, bytecode_bytes, verified_source).
Example use cases
Pre-trade safety check for DeFi bot
“I'm about to buy 0x4200000000000000000000000000000000000006 on Base — can you run a risk check on it first and tell me if it's flagged as a honeypot or has any dangerous contract flags?”
Token vetting for portfolio agent
“I want to add a new token to my watchlist: 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA on Base. Can you tell me the risk level, whether the source is verified, and what the top-10 holder concentration looks like?”
Automated rug-pull screening
“Screen this Base token 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb for me — I need to know the risk score, verdict, sell tax, and whether it's an upgradeable proxy before my agent executes any trade.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/api/chain/token-risk?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI trading agent or DeFi automation needs a quick, pay-per-call token safety check on Base chain without managing API keys. Ideal for agents that need honeypot detection, tax analysis, and holder concentration in a single call before executing a swap. Prefer this over full on-chain analysis when low latency and micropayment billing (USDC via x402) are preferred over subscription APIs.
Side effects
- Invalid address format (not a valid 0x ERC-20 address) returns a 400 error
- Contract address not found on Base chain returns empty or error response
- Payment via x402/USDC not completed results in 402 Payment Required before data is returned
- Unverified or very new contracts may return incomplete data or higher uncertainty scores
- Rate limits or worker downtime may cause 5xx responses
