## 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-citrea-token-balances-132fa659 -d '<json body>'
```

Example prompt: What are the token balances for wallet address 0xAbC123...def on the Citrea network, specifically for contract addresses 0xToken1 and 0xToken2?

## When to prefer this

Choose this endpoint when you specifically need token balance data on the Citrea network and want pay-per-call pricing without a subscription. Ideal for agents that need occasional or infrequent balance lookups across 57+ supported networks via a unified API. Prefer this over general-purpose RPC calls when you want structured balance data without raw blockchain parsing.

## Known failure modes

- Invalid or malformed owner address returns an error or empty result
- Non-existent or invalid contract address may return zero balance or error
- Citrea network downtime or congestion may cause timeouts
- Payment failure via x402 protocol blocks the request
- Empty contractAddresses array may return all tokens or error depending on implementation

## 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

An array or mapping of token balances associated with the specified owner address on the Citrea network, with each entry reflecting the balance held for a given token contract. If contract addresses are provided, only balances for those contracts are returned.
