## 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-token-info-lookup-by-contract-address-756029e3
```

Example prompt: What token is at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — can you give me the name, symbol, and decimals?

## When to prefer this

Use this endpoint when you need to resolve a raw ERC-20 contract address on Base to its human-readable token metadata (name, symbol, decimals) — especially useful before executing trades, payments, or settlements where you need to confirm token identity and precision.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address exists but is not an ERC-20 token may return empty or null fields
- Address not deployed on Base network may return 404 or empty result
- Network congestion or RPC issues may cause timeouts
- Payment of 0.01 USDC not provided results in 402 Payment Required

## How this service works

Sylphy helps wallets, apps, and AI agents execute payments and settlements with encrypted intent, policy checks, and audit proofs — while final settlement remains verifiable on Base.

## Output

A JSON object containing the token's name (e.g. 'USD Coin'), symbol (e.g. 'USDC'), contract address, and decimal precision (e.g. 6) for the specified ERC-20 contract on Base.
