x402
Tollkit Token Info – ERC-20 & SPL Token Metadata Lookup is a paid API for AI agents from extract.tollkit.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-10).
Returns the name, symbol, decimals, and total supply of an ERC-20 token on Base or Ethereum (or SPL token on Solana) given its contract/mint address, read live from the blockchain.

How this service works
ERC-20 token info on Base or Ethereum: give a contract address, get its name, symbol, decimals and total supply, read live from the chain. $0.002 per call; an address that isn't a token is not charged.
Output
A JSON object containing the token's on-chain name (e.g. 'USD Coin'), symbol (e.g. 'USDC'), decimals (e.g. 18), and total supply (as a raw integer or large number). If the address is not a valid token contract, the call is not charged and an appropriate error is returned.
Example use cases
Identify unknown token contract
“I found this contract address on Base — 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — can you tell me what token it is, its symbol, and how many decimals it uses?”
Verify token metadata before DeFi integration
“Before I integrate this token into my app, can you confirm the official name, symbol, decimals, and total supply for 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum?”
Resolve Solana SPL mint address
“What token is at Solana mint address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v — give me its name, symbol, and decimals.”
Technical details
Endpoint
POSThttps://extract.tollkit.dev/chain/token?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, live on-chain token metadata (name, symbol, decimals, total supply) directly from the blockchain rather than from a third-party aggregator or cached database. It is ideal for verifying token identity before integrating into DeFi workflows, enriching wallet or transaction data, or resolving an unknown contract address. The pay-per-call model with no account required makes it efficient for low-volume or ad-hoc lookups. Use sibling Tollkit endpoints for token price, transaction details, or wallet balances.
Side effects
- Address is not a token contract — returns an error and no charge is applied
- Invalid address format — rejected before chain read, returns validation error
- Unsupported chain specified — returns error for chains other than base/ethereum/solana
- Network/RPC timeout — chain read fails, returns a transient error
- Contract exists but doesn't implement standard ERC-20 interface — may return partial or missing fields
