## 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-abstract-token-balances-396e172d -d '<json body>'
```

Example prompt: Can you check the token balances for wallet 0xAbC123...def on the Abstract network, specifically for contracts 0xToken1... and 0xToken2...?

## When to prefer this

Choose this endpoint when you specifically need token balance data on the Abstract blockchain network. It is pay-per-call ($0.01 USDC via x402), making it cost-effective for on-demand lookups without subscription overhead. Prefer this over general-purpose blockchain explorers when you need programmatic, structured balance data for automated agents or DeFi workflows.

## Known failure modes

- Invalid or malformed owner address returns an error or empty result
- Contract address not found on Abstract network returns zero balance or empty entry
- Network outage or RPC failure returns 5xx error
- Missing required 'owner' field returns 400 bad request
- Payment failure via x402 prevents call from completing

## 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 list of token balances associated with the specified owner wallet address on the Abstract network. Each entry typically includes the token contract address, token name/symbol, and the balance amount. If contract addresses are specified, results are filtered to only those tokens.
