## 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 free-asset-radar-multi-chain-wallet-snapshot-6c36887a
```

Example prompt: Can you pull a snapshot of native token balances for wallet address 0xAbCd...1234 across all 20 supported chains?

## When to prefer this

Choose this endpoint when you need a single API call to aggregate native token balances across up to 20 blockchain networks simultaneously, rather than querying each chain individually. It is especially useful for agents building multi-chain portfolio summaries, treasury dashboards, or pre-transaction balance checks without managing multiple RPC connections.

## Known failure modes

- Invalid or malformed wallet address returns an error response
- Network timeout or edge worker unavailability returns a 5xx error
- Payment not completed (x402 protocol failure) results in a 402 Payment Required response
- Unsupported network not returned in results silently
- Empty results array if wallet has no activity on any supported network

## How this service works

Stable edge-hosted x402 utilities for autonomous agents.

## Output

A JSON object containing the queried wallet address, an array of per-network results each with network name and native token balance, and a total network count (up to 20).
