## 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-toolbox-dmarc-check-33480a06
```

Example prompt: Can you check if acme.com has a DMARC record configured and what policy it's set to?

## When to prefer this

Use this endpoint when you need a quick, no-signup DMARC lookup paid per-call via USDC over x402 — ideal for AI agents that need to check email authentication policy without maintaining API key credentials. Prefer this over manual DNS lookups when automating domain security audits at scale.

## Known failure modes

- Domain has no DMARC record published — returns empty or not-found result
- Invalid or malformed domain name input causes lookup failure
- DNS resolution timeout for the queried domain
- Payment failure via x402 protocol prevents call from completing
- Misconfigured schema parameter returns unexpected format

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object indicating whether the call succeeded and payment was accepted, along with DMARC record details such as the policy mode (none, quarantine, reject), reporting addresses, and other DNS record fields for the queried domain.
