## 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 dns-lookup-api-1fc140e3 -d '<json body>'
```

Example prompt: Can you look up the DNS records for https://example.com and tell me what A, AAAA, and MX records it has?

## When to prefer this

Choose this endpoint when you need quick, programmatic DNS record resolution for a given URL or domain — particularly when you need A, AAAA, and MX records in a single call. Prefer this over manual DNS tools when automating domain infrastructure checks, email server verification, or security research at scale.

## Known failure modes

- Invalid or malformed URL returns an error
- Private/internal domains may return empty arrays
- Rate limiting may occur at high query volumes
- Non-existent domains return empty arrays for all record types
- Network timeouts for slow-responding DNS servers
