How this service works
Token Quick Check: Base contract facts -- name, supply, owner, code. Not financial advice. Returns: a token verdict preview on one token contract: the contract facts the full verdict reads -- code size, name, symbol, decimals, total supply, owner(), proxy slots -- read from the chain. No grade, no model, no pool price, no holders, no safety or legitimacy call.
Output
Returns on-chain contract facts read directly from Base: code size, token name, symbol, decimals, total supply, owner() address, and proxy storage slot values. No AI grade, no safety assessment, no price or liquidity data, no holder information — purely the raw contract metadata.
Example use cases
Pre-screening a new Base token
“Before I invest any time in a full token report, can you grab the raw on-chain facts for this Base token contract — 0x4200000000000000000000000000000000000006 — name, symbol, supply, owner, code size, and proxy slots?”
Verifying token metadata in a DeFi dashboard
“I'm building a token list and need to confirm the official name, symbol, and decimals straight from the chain for Base contract 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb — can you fetch that for me?”
Checking contract ownership before a governance vote
“Who is the owner() of the Base token at 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA, and is it a proxy contract? Just want the contract basics from the chain.”

Endpoint
GEThttps://api.arysphere.com/v1/ventures/x402_bazaar_token_verdict_v2/base_token_verdict_preview?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.002) read of raw on-chain token facts from Base without requiring an AI verdict or pool/price data. Ideal as a pre-flight check before invoking a full token verdict, for populating token metadata in dashboards, or for lightweight contract inspection in automated pipelines. Prefer the full Base Token Verdict endpoint if you need a risk grade, red flags, or AI analysis.
Side effects
- Invalid or malformed contract address (not 0x + 40 hex) returns a validation error
- Address is not a deployed contract on Base — returns empty or zero values
- Contract does not implement standard ERC-20 methods — some fields may be null or missing
- Network/RPC timeout on Base — transient read failure
- Contract uses non-standard owner() implementation — owner field may be absent
