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 structured token metadata for the given contract address, typically including the token name, symbol, number of decimals, and total supply, sourced directly from on-chain data across 57+ supported blockchain networks.
Example use cases
Identify unknown DeFi token
“I just got sent some tokens to my wallet — the contract is 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984. Can you look up the name, symbol, and decimals so I know what I'm holding?”
Validate token contract before swap
“Before I swap into it, can you pull the on-chain metadata for contract 0x6B175474E89094C44Da98b954EedeAC495271d0F so I can confirm it's actually DAI and check the total supply?”
Enrich token list for DeFi dashboard
“I'm building a token watchlist — can you fetch the name, symbol, and decimals for the contract at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 so I can display it properly?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/stable/token/metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, pay-per-call on-chain token metadata without managing RPC nodes or API keys. It is ideal for agents that need to resolve token identity (name, symbol, decimals) from a raw contract address across a wide range of EVM and non-EVM chains, especially in contexts where you want to avoid rate limits or infrastructure overhead of free public RPCs.
Side effects
- Invalid or malformed contract address returns an error
- Contract address is not a token contract (e.g. a plain wallet or non-ERC-20 contract)
- Unsupported network or chain not covered by the 57+ networks
- Contract exists but has no standard metadata methods (non-standard token)
- Payment failure via x402 if USDC balance is insufficient
