How this service works
Token Quick Check: Base contract facts -- name, supply, owner, code. Not financial advice. A token verdict preview of one Base token contract. 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 data fields read directly from the Base blockchain for the specified token contract: contract name, symbol, decimals, total supply, owner() address, bytecode/code size, and proxy slot values. No safety grade, no price data, no holder counts, and no AI-generated verdict are included — this is a facts-only preview.
Example use cases
Pre-investment token contract sanity check
“Before I buy any of this token, can you fetch the raw contract facts for 0x4200000000000000000000000000000000000006 on Base — I want the name, symbol, total supply, owner, and whether it's a proxy contract?”
Verify token metadata for a new Base listing
“I'm seeing a new token listed on Base with contract address 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA — can you check its on-chain name, symbol, decimals, and total supply for me?”
Check if Base token is proxy-upgradeable
“Can you inspect the contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base and tell me the code size and whether there are any proxy slots, plus the owner address?”
Technical details
Endpoint
GEThttps://api.arysphere.com/v1/ventures/x402_bazaar_token_verdict_v2/base_token_facts_preview?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, low-cost ($0.002 USDC) snapshot of raw on-chain facts for a Base token contract without requiring a full AI-graded verdict. Ideal for pre-screening tokens, verifying metadata, checking proxy patterns, or feeding contract facts into a downstream analysis pipeline. Use it over a full verdict endpoint when you only need objective chain-read data and want to minimize cost and latency.
Side effects
- Invalid or non-existent contract address returns an error or empty result
- Contract address is not on Base network (wrong chain)
- Contract does not implement standard ERC-20 functions (no name/symbol/decimals), resulting in missing fields
- Network/RPC timeout causing delayed or failed response
- Rate limiting if called excessively within a short period
