## 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 synapse-api-superseed-token-metadata-lookup-33717549 -d '<json body>'
```

Example prompt: Can you look up the token metadata for the contract address 0xAbC123... on the Superseed network — I want to know the token name, symbol, and decimals?

## When to prefer this

Use this endpoint when you specifically need token metadata from the Superseed blockchain network. It is ideal when you have a contract address and need to resolve it to a human-readable token name, symbol, decimals, or supply without running your own node.

## Known failure modes

- Invalid or malformed contract address returns an error or empty response
- Contract address exists but is not a token contract (e.g. a plain wallet or non-ERC20 contract)
- Superseed network RPC unavailable causing a timeout or 503
- Payment not processed (x402 payment failure) results in 402 response
