How this service works
Wallet balances, tokens, transactions and prices on Base, Ethereum and Solana. Other Tollkit tools are described at: https://extract.tollkit.dev/openapi.json, https://attest.tollkit.dev/openapi.json, https://web.tollkit.dev/openapi.json, https://data.tollkit.dev/openapi.json.
Output
A JSON object containing the token's name, symbol, contract address, chain, decimals, total supply (human-readable and raw), a link to the block explorer, and the timestamp the data was fetched.
Example use cases
Identify unknown token contract
“I found this contract address on Base — 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — can you tell me what token it is, its symbol, and how many decimals it uses?”
Verify token decimals before DeFi trade
“Before I swap, can you confirm the decimals and total supply for the SPL mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v on Solana?”
Enrich token data for portfolio tracker
“I'm building a portfolio tracker — can you fetch the full token metadata for 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum so I have the name, symbol, and supply?”
Technical details
Endpoint
POSThttps://chain.tollkit.dev/chain/token?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain token metadata — name, symbol, decimals, total supply — for a known contract address on Base, Ethereum, or Solana. Prefer it over generic blockchain explorers when you need structured JSON output suitable for agent pipelines. It's especially useful before executing trades, displaying token info in UIs, or enriching wallet data with human-readable token names.
Side effects
- Invalid contract address format returns a validation error
- Token address not found on the specified chain returns an empty or error response
- Wrong chain specified for a valid address (e.g. Base address queried on Ethereum) may return no data
- Network or RPC timeout causes a service error
- Malformed address (not 0x hex or valid base58) rejected by pattern validation
