How this service works
558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.
Output
A JSON object containing the token's on-chain name, symbol, decimal places, total supply (as a human-readable number), and a boolean indicating whether the contract is an upgradeable EIP-1967 proxy — plus the implementation address if it is one.
Example use cases
Verify stablecoin contract before integration
“Before we integrate this token into our app, can you look up the contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base and confirm its name, symbol, decimals, and whether it's an upgradeable proxy?”
Audit unknown token from a wallet transaction
“I just received a token transfer from contract 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum — what token is this exactly, how many decimals does it have, and what's its total supply?”
Check if DeFi token uses upgradeable proxy
“Is the token at contract address 0x4200000000000000000000000000000000000006 on Base an upgradeable EIP-1967 proxy? If so, what's the implementation address?”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/erc20-token-info?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, on-chain ERC-20 token metadata directly from the contract rather than relying on off-chain token lists or price aggregators. It is especially valuable for verifying unknown tokens, auditing contracts before integration, or checking whether a token is upgradeable — particularly on Base or Ethereum mainnet.
Side effects
- Contract address does not exist on the specified network — returns null fields or error
- Address provided is not an ERC-20 token contract (e.g. an EOA or a non-token contract) — fields may be null
- Wrong network specified (e.g. contract is on Ethereum but Base was requested) — returns empty or null data
- Malformed contract address (not a valid EVM hex address) — validation error
- Network RPC timeout or congestion — request may fail or return partial data
