# NetIntel Domain Due Diligence

> NetIntel Domain Due Diligence is a paid API for AI agents from netintel-production-440c.up.railway.app, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-15).

Assesses a domain name for availability, registration status, valuation tier, and TLD pricing alternatives, returning a graded due-diligence report.

## 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-849c2b30
```

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

## When to prefer this

Use this endpoint when you need a comprehensive, scored due-diligence snapshot of a domain — combining availability, WHOIS ownership, expiry, value appraisal, and cross-TLD pricing in a single graded call. Prefer it over bare WHOIS lookups when you want actionable valuation context and letter-grade summarization.

## Known failure modes

- Missing or invalid domain parameter returns a 400/validation error
- Domain with unsupported or malformed TLD may return incomplete section data
- Payment failure via x402 (insufficient USDC balance or wrong network) returns 402
- Unavailable external data sources (WHOIS, registrar APIs) may cause sections_failed > 0 with partial results
- Railway hosting downtime returns 5xx errors

## 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

Returns a JSON object with a letter grade (e.g. 'C'), numeric score (0-100), verdict string (e.g. 'taken_premium'), an array of findings, and a sections object containing: availability (registered/available status, registrar, expiry), appraisal (value tier and score), and tld_pricing (cheapest available alternative domains). Also includes generation timestamp and counts of passing/failing sections.
