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 Base network token contract, typically including the token name, symbol, and decimal precision as stored in the smart contract.
Example use cases
Identify unknown DeFi token
“I found this contract address on Base: 0x4200000000000000000000000000000000000006 — can you tell me what token it is, its symbol, and how many decimals it uses?”
Validate token before swap
“Before I swap into this token, can you look up the on-chain metadata for contract 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb on Base so I can confirm it's the right asset?”
Enrich portfolio tracker with token info
“I'm building a portfolio dashboard and need the name, symbol, and decimals for these Base token contracts — can you start with 0x2Ae3F1Ec7F1F5012CFEab0185bfc7aa3cf0DEc22?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/base/token/metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, pay-per-call token metadata specifically on the Base network without needing a subscription or API key. Ideal for agents that need lightweight, on-demand token lookups (name, symbol, decimals) for a specific contract address without pulling full indexer data.
Side effects
- Invalid or malformed contract address returns an error
- Contract address does not correspond to a token contract (e.g. a non-ERC-20 contract) may return empty or error
- Network unavailable or RPC issues may cause timeout
- Payment failure via x402 protocol results in 402 response and no data returned
- Contract deployed on a different network (not Base) will not return valid metadata
