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 raw on-chain contract facts for the specified Base ERC-20 token contract: code size, token name, symbol, decimals, total supply, the result of owner(), and proxy storage slot values. No AI-generated grade, no safety assessment, no pool price, no holder count — only chain-read data.
Example use cases
Pre-audit token contract sanity check
“Before I run a full verdict on this Base token, grab the raw contract facts for 0x4200000000000000000000000000000000000006 — name, symbol, decimals, total supply, owner, and code size.”
Proxy detection on suspicious token
“I want to know if the Base token at 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA is a proxy contract — can you fetch its on-chain facts including proxy slots?”
Token metadata lookup for portfolio tracker
“Look up the on-chain details for the Base ERC-20 at 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb — I need the token name, symbol, decimals, and total supply straight from the chain.”

Endpoint
GEThttps://api.arysphere.com/v1/ventures/x402_bazaar_token_verdict_v2/base_erc20_token_facts_preview?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, fast read of raw ERC-20 contract facts on Base without triggering a full AI-scored verdict. Ideal as a pre-flight check before running a more expensive full verdict, for populating token metadata in a portfolio tracker, or when you only need chain-verifiable facts (name, supply, owner, proxy detection) rather than a risk grade or market data.
Side effects
- Invalid contract address format (not a valid 0x + 40 hex address) — returns validation error
- Address is not a deployed contract on Base — may return empty or zero values
- Contract does not implement standard ERC-20 methods — some fields may be null or unavailable
- Base RPC node timeout or unavailability — returns upstream error
- Rate limiting or payment failure — returns 402 or rejection
