Output
A JSON object containing on-chain facts (token name, total supply, owner address, ownership renounced boolean, upgradeable proxy flag, source verification status, privileged function hints such as mint/pause/blacklist presence, WETH/USDC liquidity on Uniswap V2/V3 and Aerodrome), a list of risk flags, and a short plain-language summary. Does not include holder distribution data or trade simulation results.
Example use cases
Vetting a new Base meme coin
“Before I ape into this new token, can you pull the on-chain facts for contract 0xAbCd1234...5678 on Base — I want to know if ownership is renounced, if there are any mint or pause functions, whether the source is verified, and what the Uniswap V3 liquidity looks like?”
DeFi bot pre-trade safety check
“Run a quick contract check on Base token 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — give me the risk flags, any privileged functions like blacklist or mint, proxy upgrade status, and a plain-language summary of whether it looks risky.”
Research report on a listed Base token
“I need on-chain facts for the Base token at address 0x4200000000000000000000000000000000000006 — get me the name, total supply, owner, whether ownership is renounced, source verification status, and liquidity on both Uniswap and Aerodrome, plus any risk flags you find.”
Technical details
Endpoint
POSThttps://2-28-111-166.sslip.io/v1/token-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, verifiable on-chain facts about a specific ERC-20 token on the Base chain — especially for pre-trade safety checks, DeFi due diligence, or automated risk scoring pipelines. It is purpose-built for Base and checks Base-specific DEXes (Aerodrome) alongside Uniswap V2/V3. Prefer this over generic blockchain explorers when you need structured JSON output with risk flags and a plain-language summary in a single call. Not suitable for Ethereum mainnet or other chains, holder distribution analysis, or trade simulation.
Side effects
- Invalid or malformed contract address returns an error
- Contract address not found on Base chain returns not-found or empty result
- Unverified source code means privileged function analysis may be incomplete
- Rate limiting or payment failure returns a 402 or rejection response
- Network timeout if Base RPC is slow or congested
