# Liangyi Domain Audit API

> Liangyi Domain Audit API is a paid API for AI agents from liangyi-domain-audit.orelumia-offer-worker.workers.dev, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Audits a public domain's DNS and email-delivery records, returning MX, SPF, DMARC, DNSSEC, and resolver status in a single call.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 liangyi-domain-audit-api-d3c0a012
```

Example prompt: Can you run a full DNS and email-delivery audit on acmecorp.com — I want to know if they have MX, SPF, and DMARC records set up and whether DNSSEC is authenticated?

## When to prefer this

Choose this endpoint when you need a single, pay-per-call lookup of a domain's email-delivery and DNS security posture — specifically MX, SPF, DMARC presence, and DNSSEC authentication — without managing DNS resolver infrastructure yourself. Ideal for one-off audits, agent-driven domain vetting workflows, or pre-send email deliverability checks where bulk subscription pricing is unnecessary.

## Known failure modes

- Invalid or non-existent domain returns resolver error or empty records
- Domain without any DNS records may return all 'has*' flags as false
- Payment not processed (402) blocks the request
- Malformed domain input (e.g. includes scheme or path) may cause validation error
- Temporary DNS resolver unavailability may yield incomplete results

## How this service works

Pay-per-call audit of public DNS and email-delivery records.

## Output

Returns a structured object containing the audited domain name, the timestamp of the check, a boolean for DNSSEC authentication, resolver status details, and an email sub-object with booleans and raw record arrays for MX, SPF, and DMARC presence.
