How this service works
Pay-per-call utilities for autonomous agents, paid with x402 (USDC on Base, or USDC/USDT on Celo; no account, no API key).
Output
A JSON object containing: an array of risk flag strings (e.g. 'UPGRADEABLE_PROXY'), proxy details including implementation address if applicable, the token symbol, decimals, and a risk level string (e.g. 'medium'). This gives agents a quick security snapshot of any ERC-20 token contract on Base before interacting with it.
Example use cases
Pre-swap token safety check
“I'm about to swap into this token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — can you check if it has any red flags like upgradeable proxies or admin controls before I proceed?”
DeFi agent risk preflight
“My agent is about to add liquidity using this contract address on Base: 0x4200000000000000000000000000000000000006 — run a risk check and tell me the risk level, proxy setup, and any flags before it does anything.”
Unknown token contract audit
“Someone sent me tokens from 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb on Base and I want to know if the contract is sketchy — check if it's a proxy, what its risk level is, and pull the symbol and decimals for me.”

Endpoint
GEThttps://newbotlabor--254ecdfcc2de11f19b541607ee4eb77e.web.val.run/api/base/token-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent needs a fast, pay-per-call token risk assessment on Base without setting up an account or API key. It is ideal for pre-trade or pre-interaction preflight checks where the agent needs to detect upgradeable proxy patterns and risk classification before committing to a transaction. Prefer it over general blockchain explorers when you need structured risk flags and proxy metadata in a single call, paid atomically with USDC via x402.
Side effects
- Invalid or malformed contract address returns an error or empty result
- Address is not a contract (EOA) may return no token metadata
- Contract not deployed on Base returns a not-found or null response
- Rate limiting or payment failure due to x402 USDC payment issues
- Network timeouts when querying Base RPC nodes
