How this service works
ERC-20 token metadata on Base — name, symbol, decimals, total supply. Pay-per-call via x402.
Output
A JSON object containing the token's official name, ticker symbol, decimal precision, total supply as a formatted number, total supply in atomic units, the contract address, network identifier (base), and a timestamp of when the data was fetched.
Example use cases
Identify unknown Base token contract
“I have a contract address on Base — 0x4200000000000000000000000000000000000006 — can you tell me what token this is, its symbol, and how many decimals it uses?”
Build token display for DeFi dashboard
“For my DeFi dashboard I need the full metadata for USDC on Base: official name, symbol, decimals, and current total supply — the contract is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.”
Validate token decimals before swap
“Before I execute this swap, can you confirm how many decimals the token at 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb on Base uses, and what its full name and symbol are?”
Technical details
Endpoint
POSThttps://fiatdock.com/v1/chain/token-metadataWhen to prefer
Use this endpoint when you need authoritative on-chain token metadata (name, symbol, decimals, total supply) for any ERC-20 on Base without maintaining your own RPC node. Prefer it over token price/safety endpoints when you only need structural metadata, not market data or risk signals. It is ideal for normalizing raw token amounts (using decimals), labeling tokens in a UI, or verifying a contract's identity before executing a transaction.
Side effects
- Invalid or non-ERC-20 contract address returns an error — the address may be an EOA or non-token contract
- Contract not deployed on Base returns a not-found or zero-data response
- Malformed contract address (wrong length, bad checksum) returns a validation error
- Payment failure via x402 (insufficient USDC) results in a 402 Payment Required response
- Network congestion may cause slightly stale totalSupply if chain RPC is delayed
