## 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-pharos-token-balances-87640f61 -d '<json body>'
```

Example prompt: What are the token balances for wallet 0xAbC123...def on Pharos, specifically for the contracts 0xToken1... and 0xToken2...?

## When to prefer this

Use this endpoint when you need fast, pay-per-call token balance lookups on the Pharos network for one or more ERC-20 or compatible token contracts without setting up your own RPC infrastructure. Prefer it over generic blockchain explorers when you need structured, machine-readable balance data directly in an agent workflow at low cost ($0.01/call).

## Known failure modes

- Invalid or malformed owner address returns an error or empty result
- Invalid contract address in the array causes partial or full failure
- Address with no token holdings returns zero balances
- Network congestion or RPC timeout causes delayed or failed response
- Unsupported token standard on Pharos network may return no data

## 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 a mapping of token contract addresses to their respective balances held by the specified owner address, providing a real-time snapshot of on-chain token holdings on the Pharos network.
