NetIntel Bulk Domain Availability Check
x402
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 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.
Example use cases
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.”
Technical details
Endpoint
POSThttps://netintel.dev/bulk-domain/checkWhen to prefer
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.
Side effects
- 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
