## 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 netintel-domain-due-diligence-56e271c8
```

Example prompt: Can you run a full due diligence check on stripe.com — I want to know if it's available, who owns it, when it expires, what grade and value score it gets, and whether there are cheaper alternatives?

## When to prefer this

Use this endpoint when you need a comprehensive, single-call domain assessment covering availability, ownership, valuation, and pricing alternatives — rather than making separate WHOIS, availability, and appraisal API calls. Ideal for domain acquisition research, brand protection, competitive intelligence, or investment screening.

## Known failure modes

- Invalid or malformed domain input returns a validation error
- Domain lookup timeout if registry is slow to respond
- Unsupported TLD may result in partial section data with sections_failed > 0
- Missing required 'domain' query parameter returns a 400 error
- Network or registry unavailability may cause partial results

## How this service works

One call combines domain availability, heuristic value appraisal, and TLD pricing into a single acquisition brief — tells an agent whether a name is available, what it's worth, and what it costs across TLDs, concurrently and with graceful partial-failure handling.

## Output

A JSON object containing the domain's letter grade (e.g. 'A', 'C'), numeric score (0–100), verdict (e.g. 'taken_premium'), availability status, registrar name, expiry date, domain appraisal value tier and score, cheapest alternative TLD registration price, number of sections passed/failed, and a timestamp of when the report was generated.
