How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns on-chain metadata for the specified Ethereum token contract, including token name, symbol, number of decimals, and potentially token standard (ERC-20, ERC-721, etc.). Response is sourced directly from blockchain data across supported networks.
Example use cases
DeFi portfolio token identification
“I have a list of Ethereum contract addresses from my wallet and I need to know the name and symbol for each token — can you start by looking up 0xdAC17F958D2ee523a2206206994597C13D831ec7?”
NFT contract inspection
“What's the official token name and standard for the contract at 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum?”
Smart contract due diligence
“Before I interact with this contract, can you tell me the token metadata for 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 on Ethereum — specifically the name, symbol, and decimals?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/ethereum/token/metadata?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, pay-per-call on-chain token metadata for Ethereum contracts without managing your own RPC infrastructure or API keys. Ideal for agents that need occasional token lookups rather than high-volume streaming, and when cost predictability at $0.01/call is acceptable.
Side effects
- Invalid or malformed contract address returns an error
- Contract address exists but is not a token contract (no metadata interface) may return empty or error
- Network congestion or RPC issues may cause timeouts
- Non-Ethereum contract addresses (e.g. Solana) will not be valid for this endpoint
- Payment failure via x402 results in 402 response before data is returned
