## 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-inspector-full-record-lookup-a-aaaa-mx-ns-txt-soa-caa-spf-dmarc-dba94a10 -d '<json body>'
```

Example prompt: Can you pull up the full DNS inspection for stripe.com — I want to see all the records including SPF, DMARC, CAA, MX, and which mail and DNS providers they're using?

## When to prefer this

Choose this endpoint when you need a single, consolidated DNS inspection that goes beyond raw record retrieval — specifically when you need parsed SPF/DMARC interpretation, provider detection (mail host, DNS host), CAA verdict classification, and connected-services inference all in one paid call. Prefer it over generic DNS resolvers when you need enriched, agent-ready output rather than raw wire-format DNS responses.

## Known failure modes

- Domain not found / NXDOMAIN — 'found' field returns false with empty records
- Invalid domain format in request body — likely 400 validation error
- Timeout on DNS resolution for slow authoritative nameservers
- Partial record availability if some record types are not published for the domain
- Payment failure / x402 challenge not met — endpoint returns 402 before processing
