## 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 robinhood-token-metadata-lookup-d749870e -d '<json body>'
```

Example prompt: What are the name, symbol, and decimals for the token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48?

## When to prefer this

Use this endpoint when you need fast, pay-per-call token metadata lookup by contract address without managing your own blockchain node or indexer. Prefer it when working within a Synapse/x402 payment workflow and you need lightweight token identification (name, symbol, decimals) rather than full on-chain state or transaction history.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address does not correspond to a token (e.g. it's a general smart contract) may return empty or error
- Network unavailable or Robinhood data layer outage returns 5xx
- Insufficient USDC balance to cover the $0.01 per-call fee blocks the request
- Contract exists but has no standard metadata (non-ERC-20) may return partial data

## How this service works

## Output

Returns on-chain token metadata for the specified contract address, likely including token name, symbol, decimal precision, and other contract-level identifiers sourced via Robinhood's data infrastructure.
