## 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-datashop-dns-resolver-9d54aa47
```

Example prompt: Before I email this client, can you check if stripe.com is properly set up to receive email — I need the MX, SPF, and DMARC records and whether it's actually email-ready?

## When to prefer this

Choose this endpoint when you need real-time DNS resolution without running your own DNS client, especially for the email readiness check (check=email) which combines MX, SPF, and DMARC into a single actionable signal before emailing or invoicing a contact. Prefer over general WHOIS/RDAP endpoints when you need record-level DNS data rather than registration metadata.

## Known failure modes

- Domain does not exist or has no records of the requested type — returns empty records list
- Invalid DNS record type supplied — schema validation error
- Cloudflare DNS-over-HTTPS upstream timeout — service unavailable response
- Malformed domain name input — query rejected
- Payment not provided or insufficient — 402 Payment Required response

## How this service works

Live DNS records resolved via Cloudflare 1.1.1.1 DNS-over-HTTPS (public facts, real time). Query: ?name=anthropic.com&type=MX (type in A|AAAA|MX|TXT|NS|CNAME, default MX). Or ?name=anthropic.com&check=email -> combined MX + SPF + DMARC with an email_ready boolean, useful before emailing or invoicing a contact. JSON with records list; 5 min cache.

## Output

A JSON object containing a records list with resolved DNS entries for the queried type; when check=email is used, returns combined MX, SPF, and DMARC records plus an email_ready boolean indicating whether the domain has a working email infrastructure. Results are cached for 5 minutes.
