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 a verdict (e.g. 'OK', 'WARN', 'BLOCK'), numeric risk_score (0–100), risk_level string, can_sell and should_buy booleans, an array of flag strings (e.g. 'upgradeable_proxy'), an array of human-readable reason strings, token metadata (symbol, decimals, holder_count), trading data (buy_tax, sell_tax, honeypot simulation result, top10_holder_pct), and contract metadata (is_contract, bytecode_bytes, verified_source). Payment is $0.01 USDC via x402 on Base.
Example use cases
Pre-trade honeypot check for DeFi agent
“Before my agent buys this new Base token at 0x4200000000000000000000000000000000000006, check if it's a honeypot and what the sell tax is — I don't want to get stuck holding it.”
Portfolio risk screening for onchain holdings
“Scan the token contract 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb on Base and give me a risk verdict and score so I know if it's safe to keep in my portfolio.”
Whale concentration alert before entering position
“Check the token at 0x2Ae3F1Ec7F1F5012CFEab0185bfc7aa3cf0DEc22 on Base — specifically I want to know what percentage the top 10 holders control and whether the contract source is verified before I take a position.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/v1/token-security?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs a rapid, low-cost ($0.01) security assessment of an ERC-20 token on Base before executing a swap, investment, or onchain action — especially when you need honeypot detection, tax rates, holder concentration, and contract verification in a single call without requiring an API key. Prefer it over full audit services when speed and micropayment pricing matter. It is Base-specific; use alternative endpoints for Ethereum mainnet or other chains.
Side effects
- Invalid or malformed address (not a 0x + 40 hex char format) returns a 400 error
- Contract address not deployed on Base returns an error or empty result
- x402 payment failure (insufficient USDC balance or wrong chain) blocks the request
- Network latency from Cloudflare Worker or Base RPC timeouts may cause 5xx errors
- Newly deployed contracts with no on-chain history may have incomplete holder or tax data
