## 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 defi-hugen-tokyo-c5ca76d3
```

Example prompt: Show me all the blockchain networks supported by the DeFi security scanning API — I need their chain IDs and names so I know which chains I can run security audits on.

## When to prefer this

Use this endpoint before calling other defi.hugen.tokyo security scanning endpoints to discover available chain IDs and names, or to validate that a target chain is supported before submitting audit, phishing-check, or wallet-flag requests.

## Known failure modes

- Payment not included — returns 402 Payment Required
- Service unavailable — returns 5xx error
- Unexpected empty response if upstream data source is unreachable
