# x402 Base Tools – ERC-20 Token Info

> 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).

Returns the name, symbol, decimals, and total supply of any ERC-20 token on the Base blockchain, plus a Basescan link, given a token address or well-known symbol.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-base-tools-erc-20-token-info-5f76186a
```

Example prompt: What are the name, symbol, decimals, and total supply of the USDC token on Base — and can you give me its Basescan link?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
