How this service works
ERC-20 token profile read directly from the contract on Base or Ethereum: name, symbol, decimals, total supply, bytecode size and whether it is an upgradeable EIP-1967 proxy (with implementation address).
Output
Returns a JSON object with the token's on-chain name, symbol, decimals, total supply (as a number), bytecode size, a boolean indicating whether it is an EIP-1967 upgradeable proxy, the implementation address if applicable, the network name, a block explorer URL for the contract, and an optional note field.
Example use cases
Verify unknown token contract before trading
“Before I swap into this token, can you pull the on-chain details for contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — give me the name, symbol, decimals, and whether it's a proxy contract?”
Audit proxy upgradeability of a DeFi token
“I need to know if the token at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 on Ethereum is an upgradeable EIP-1967 proxy — if it is, what's the implementation address?”
Populate token metadata for a portfolio tracker
“Can you fetch the full on-chain metadata for the ERC-20 at 0x4200000000000000000000000000000000000006 on Base — I need name, symbol, decimals, and total supply to add it to my portfolio tracker?”
Technical details
Endpoint
POSThttps://api.vextorium.com/info-token-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, on-chain ERC-20 token metadata read directly from the contract — not from a third-party aggregator that may be stale or inaccurate. Especially useful for verifying upgradeability (EIP-1967 proxy detection) and getting the actual implementation address, which most token APIs do not expose. Best for Base and Ethereum; choose a different endpoint for other EVM chains.
Side effects
- Invalid or non-existent contract address returns null fields or an error
- Contract address is not an ERC-20 token (e.g. EOA or non-token contract) — fields like name/symbol may be null
- Unsupported network value (not 'base' or 'ethereum') causes a validation error
- Network congestion or RPC unavailability may cause timeouts
- Non-checksummed or malformed address may cause a parsing error
