How this service works
Pay-per-call token risk check for Base: send a Base ERC-20 contract address, get deterministic JSON risk flags (owner/renounced, upgradeable proxy, mint/pause/blacklist/fee functions, on-chain Uniswap v2/v3 + Aerodrome liquidity, holder concentration) and a rule-based risk_level. Use before buying or listing an unfamiliar Base token. $0.01 USDC. Invalid input returns 400 and is not charged. Not financial advice.
Output
A JSON object containing: token metadata (name, symbol, decimals), contract flags (owner_renounced, is_eip1967_proxy), detected function risks (mint, pause, blacklist, fee), on-chain liquidity estimates in USD from Uniswap v2/v3 and Aerodrome, holder concentration metrics (top holder share and top-10 share excluding pools/burn), and a deterministic risk_level string (e.g. 'low', 'medium', 'high'). Invalid inputs return HTTP 400 and are not billed.
Example use cases
Pre-buy token safety screen
“I'm about to buy some of this Base token at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed — can you check it for risk flags like mint functions, blacklisting, upgradeable proxy, and tell me the overall risk level and liquidity before I commit?”
Token listing due diligence
“We're considering listing this Base ERC-20 at 0x940181a94A35A4569E4529A3CDfB74e38FD98631 on our DEX aggregator — run a risk check on it and flag anything concerning like high holder concentration, pausing functions, or non-renounced ownership.”
Portfolio watchlist risk audit
“Can you check the risk profile for the Base token contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — I want to know the holder concentration stats, whether it's a proxy, and its current on-chain liquidity estimate?”
Technical details
Endpoint
POSThttps://api.x402risk.com/v1/token-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, deterministic, pay-per-call on-chain risk assessment specifically for Base chain (chain ID 8453) ERC-20 tokens. It is ideal for pre-trade screening, automated listing pipelines, or portfolio audits where you need concrete flags (mint, blacklist, proxy, holder concentration, liquidity) without integrating a full blockchain node or indexer. Prefer it over generic token info APIs when risk classification and contract security heuristics are the primary concern.
Side effects
- 400 Bad Request if the address is not a valid 0x-prefixed 40-hex-character string (not charged)
- Address exists but is not a deployed ERC-20 contract on Base chain 8453
- On-chain data temporarily unavailable for liquidity or holder analysis
- Token is too new or obscure to have meaningful holder/liquidity data
- Heuristic flags may produce false positives or miss obfuscated risks (per disclaimer)
