x402
x402 Base Tools – ERC-20 Token Info is a paid API for AI agents from wt7tysfcmjm8fpzl.68r.lambda-web.us-east-1.on.aws, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-30).

How this service works
Base mainnet data for agents, read live from the chain and paid per call in USDC: gas prices and costs, token prices from Uniswap and Aerodrome pools, balances, token info, transaction decoding, x402 payment checks, EIP-3009 authorization status, Basenames and address profiles. Lookups of things that do not exist are not charged.
Output
A JSON object containing the token's canonical name, symbol, checksummed contract address on Base, number of decimal places, formatted total supply string, and a Basescan URL for the contract.
Example use cases
Verify unknown token contract
“I just got sent some tokens on Base to my wallet from address 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA — can you look up what token that actually is, its symbol, decimals, and total supply?”
Build token metadata display
“I'm building a token info card for my DeFi dashboard — can you pull the full metadata for WETH on Base, including its contract address, decimals, total supply, and a link to Basescan?”
Confirm total supply before trade
“Before I put in a big order, can you check the total supply and decimals for the cbBTC token on Base so I can calculate market cap?”
Technical details
Endpoint
GEThttps://wt7tysfcmjm8fpzl.68r.lambda-web.us-east-1.on.aws/v1/token?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need canonical ERC-20 token metadata (name, symbol, decimals, total supply) specifically on the Base blockchain, and you have either a contract address or a well-known symbol. Prefer this over general Ethereum token APIs when the target chain is Base, and over price endpoints when you need supply/decimals rather than USD value.
Side effects
- Unknown or unrecognized token symbol returns an error or empty result
- Invalid Ethereum address format causes a bad request error
- Token not deployed on Base (e.g. Ethereum mainnet token) returns no result
- Network or Lambda timeout if Base RPC is slow
- Payment not settled (x402) causes a 402 response before data is returned
