# x402 Base Tools – ERC-20 Token Info

> x402 Base Tools – ERC-20 Token Info is a paid API for AI agents from base.kagurazaka.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-30).

Returns the name, symbol, decimals, total supply, and Basescan link for any ERC-20 token on Base, identified by contract address or well-known symbol.

## 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-4f018372
```

Example prompt: What are the full ERC-20 details for USDC on Base — give me the name, symbol, decimals, total supply, and its Basescan link.

## When to prefer this

Use this endpoint when you need authoritative ERC-20 metadata (name, symbol, decimals, total supply) for a token on the Base network, especially when you have only a contract address or a ticker symbol. Prefer it over generic blockchain explorers when you need a structured JSON response suitable for programmatic use or when you need to enrich token data in an automated pipeline.

## Known failure modes

- Unknown or unrecognized token symbol returns an error or empty result
- Invalid contract address format causes a validation error
- Token exists on a different chain but not on Base — returns not found
- Address is a contract but not an ERC-20 token — metadata fields unavailable
- Network or RPC timeout causes a delayed or failed response

## How this service works

Name, symbol, decimals and total supply of an ERC-20 token on Base, by address or well-known symbol, with its Basescan link.

## Output

A JSON object containing the token's canonical name, symbol, checksummed contract address on Base, number of decimals, formatted total supply, and a Basescan URL for the token.
