## 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 delx-commerce-mx-host-parser-26cdefbd -d '<json body>'
```

Example prompt: Parse this raw MX record for me — '10 mail.example.com' — and tell me what the mail host and preference value are.

## When to prefer this

Choose this endpoint when you have a raw MX record string (e.g. retrieved from a DNS lookup) and need to programmatically extract the mail host and preference value as structured data without implementing your own parser. It is ideal for lightweight, pay-per-use DNS record processing within an agent pipeline where no signup or subscription is required and cost is predictable at $0.001 per call.

## Known failure modes

- Malformed or empty MX record string returns a parsing error
- Missing 'mx' field in request body returns a validation error
- MX record with non-standard formatting may yield unexpected host extraction
- Network or service unavailability returns a 5xx error
- Invalid USDC payment or x402 payment failure blocks the request

## How this service works

## Output

Returns a JSON object containing the parsed mail host (e.g. 'mail.example.com'), the MX preference/priority number (e.g. 10), and a schema identifier string ('delx/util-mx-host-parse/v1') confirming the response format.
