## 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 tripguard-fare-intelligence-chain-token-info-e883f04e -d '<json body>'
```

Example prompt: Look up the on-chain token metadata for the contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — I need the symbol, decimals, and total supply.

## When to prefer this

Use this endpoint when you need authoritative on-chain ERC-20 token metadata (name, symbol, decimals, supply) for a contract on the Base network, especially without maintaining your own RPC infrastructure or API keys. Prefer it over off-chain token registries when you need raw supply figures or need to verify a contract's actual on-chain properties rather than curated listing data.

## Known failure modes

- Invalid or malformed token address returns an error or empty response
- Token address not deployed on Base network yields no data
- Network connectivity issues with the Base RPC may cause timeouts
- Unrecognized token contracts may return incomplete metadata

## How this service works

Real-time airfare intelligence for AI travel-booking agents: flight price-drop prediction, fare-fraud and deal-legitimacy verification, and verified booking links for any route and date. Pay-per-call in USDC on Base. No API key.

## Output

Returns a JSON object with the token's human-readable name, ticker symbol, decimal precision, formatted total supply, and raw total supply integer for a given contract address on the Base network.
