## 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 x402-utilities-hub-dns-lookup-5d13dd74 -d '<json body>'
```

Example prompt: Can you do a DNS lookup for example.com and tell me what IP address it resolves to?

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-use DNS lookups without setting up DNS infrastructure yourself, and you are already operating within the x402 micropayment ecosystem on Base. Useful for AI agents that need occasional DNS resolution as part of a larger workflow without committing to a full DNS API subscription.

## Known failure modes

- Invalid or malformed domain name in query parameters returns an error
- Non-existent domain (NXDOMAIN) returns empty or error response
- Payment failure via x402 protocol prevents query execution
- Missing required queryParams field results in a validation error
- Network timeout if upstream DNS resolver is unavailable
