# NetIntel Bulk Domain Availability Check

> NetIntel Bulk Domain Availability Check is a paid API for AI agents from netintel.dev, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15, last successful call 2026-07-22).

Checks availability and registration status for multiple domain name combinations (names × TLDs) in a single call, returning a graded report with registrar info and expiry dates.

## 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-bulk-domain-availability-check-0a16e4f3 -d '<json body>'
```

Example prompt: Check availability for the names 'acme', 'acmehq', and 'acmepro' across .com, .io, and .net — I want to know which combinations are available, who owns the taken ones, and when they expire.

## When to prefer this

Use this endpoint when you need to evaluate multiple domain name candidates and TLD combinations in a single call rather than checking one domain at a time. It is ideal for brand naming research, startup domain discovery, or pre-launch domain strategy where you want a graded summary with registrar and expiry metadata across many combinations simultaneously.

## Known failure modes

- Invalid or malformed domain names in request body — returns 400 error
- No domain names or TLDs provided — returns 400 validation error
- Payment not included or insufficient USDC — returns 402 Payment Required
- Too many name/TLD combinations exceeding endpoint limits — returns 429 or 400
- WHOIS/registry lookup timeout for a specific TLD — partial results or error entry for that domain
- Rate limiting if called too rapidly in succession

## How this service works

Check availability of many domain names across multiple TLDs in a single call — submit up to 50 name/TLD combinations and get back per-domain registration status, registrar, and expiry concurrently, so agents can scan an entire naming shortlist or brand portfolio in one request instead of dozens. Caveat: when both RDAP and DNS are unreachable, status reads 'available' — re-check surprising availables on premium names.

## Output

A JSON object containing an overall availability grade (A–F) and score (0–100), a results array with per-domain status (registered/available), registrar name, expiry date, days until expiry, counts of taken vs. available domains, a list of names available across all checked TLDs, and findings with deductions explaining the grade.
