## 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 phantom-api-superseed-token-balances-0c17fe2b -d '<json body>'
```

Example prompt: What are all the token balances for wallet 0xAbC123...def on the Superseed network? Also check specifically for the tokens at contract addresses 0x111... and 0x222...

## When to prefer this

Use this endpoint when you specifically need token balance data on the Superseed network. It is well-suited for pay-per-call use cases where you only need occasional balance lookups without a persistent subscription. Prefer this over generic blockchain explorers when programmatic, structured balance data is needed for Superseed wallets in an agent workflow.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Contract addresses that don't exist on Superseed return zero or null balances
- Network downtime or RPC failures may result in 500-level errors
- Missing required 'owner' field causes a validation error
- Wallet with no token holdings returns an empty balances array

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns on-chain token balance data for the specified owner wallet on the Superseed network, including balances for each requested ERC-20 contract address (or all held tokens if no contracts are specified).
