## 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 util-beauty-dns-lookup-bfe26419 -d '<json body>'
```

Example prompt: Can you look up the DNS records for example.com — I want to see its A, MX, and TXT records to check how it's configured?

## When to prefer this

Choose this endpoint when you need programmatic DNS lookups within an agent workflow, especially when you want pay-per-use pricing via USDC x402 or prepaid API keys without managing your own DNS resolver infrastructure. Ideal for lightweight, on-demand DNS checks in automated pipelines where cost predictability matters.

## Known failure modes

- Domain does not exist (NXDOMAIN) — ok: false with error message
- Invalid domain name format — validation error in response
- DNS timeout or upstream resolver failure — error with retry suggestion
- Rate limit or insufficient credits — 402 payment required or credit error
- Unsupported record type query — error indicating valid record types
