## 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 sylphy-agent-erc-20-token-info-lookup-361e35e8
```

Example prompt: Can you look up the ERC-20 token info for contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — I need the token name, symbol, and decimals.

## When to prefer this

Use this endpoint when you need to resolve ERC-20 token metadata (name, symbol, decimals) from a contract address specifically on the Base L2 network. Prefer this over generic blockchain explorers when you need a lightweight, pay-per-call programmatic API response rather than a web scrape, or when operating within a Base/DeFi agent workflow.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address does not correspond to an ERC-20 token on Base
- Contract exists but is not verified or has no metadata
- Network or RPC issues cause a timeout
- Payment of $0.01 USDC not received, returning 402 Payment Required

## How this service works
