How this service works
Lookup token by contract address
Output
Returns detailed metadata about the fungible token (cryptocurrency/DeFi asset) associated with the given contract address, including token name, symbol, decimals, logo, and chain-specific implementation details as indexed by Zerion.
Example use cases
Identify swapped token for portfolio tracking
“I just received a token at contract 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum, but I don't know what it is. Can you look up the token name, symbol, and how many decimals it uses so I can add it to my portfolio?”
Verify token legitimacy before trading
“Someone sent me a contract address 0x95aD61b0a150d79219dCF64E1E6Cc01f0B64C4cE on Polygon and claims it's a major DeFi token. Can you resolve this address to tell me what token it actually is and confirm its metadata?”
Resolve smart contract address to token name
“I'm looking at a smart contract interaction on Arbitrum with address 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5F86, but I can't tell what token it represents. What's the actual token name, symbol, and decimal places?”
Technical details
Endpoint
GEThttps://api.zerion.io/v1/fungibles/by-implementation?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have a specific on-chain contract address and need to resolve it to a human-readable token identity (name, symbol, decimals) within the Zerion DeFi ecosystem. Prefer over general token search when you already know the exact contract address. Best for ERC-20 and fungible token lookups across chains supported by Zerion.
Side effects
- Contract address not found in Zerion index — returns 404 or empty result
- Invalid contract address format — returns 400 bad request
- Contract exists on-chain but token not indexed by Zerion — no result
- Network/chain not supported — no result returned
- Payment not included or insufficient — 402 Payment Required
