## 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 public-dns-record-inventory-purchase-a-aaaa-mx-ns-txt-caa-73ccabe0 -d '<json body>'
```

Example prompt: Can you pull the full DNS record inventory for example.com — I need all record types: A, AAAA, MX, NS, TXT, and CAA?

## When to prefer this

Choose this endpoint when you need a comprehensive, all-record-type DNS inventory for a domain in a single call rather than querying individual record types separately, and when your agent operates within the x402 micropayment (USDC) infrastructure on the402.ai marketplace.

## Known failure modes

- Invalid or non-existent domain name returns an error or empty record set
- Payment authorization failure (insufficient USDC balance) blocks job creation
- Job created but DNS resolution times out — status field reflects failure state
- Malformed POST body causes 4xx response
- Service temporarily unavailable on the402.ai platform causes 5xx
