At a glance

Here is where 1Lookup wins against HackerTarget, and where HackerTarget still wins.

Both turn a domain into its DNS records over an API. HackerTarget is a security toolbox: a free tier of 50 calls a day with no sign-up, then yearly memberships that add scanners and network tools and set a daily allowance of calls shared by all of its tools. 1Lookup is one DNS call: the A, AAAA, CNAME, MX, NS, TXT, CAA and SOA records returned as JSON, the mail provider and the DNS host worked out from them, and the names behind an IP address on the same endpoint, at a flat credit price on a balance that also pays for phone, email and IP checks.

1lookupWhere 1Lookup wins

JSON by default, with all eight record types, CAA included, and the mail provider and DNS host named from them
Nothing is billed when a name does not exist, has none of the eight types or does not answer in time, and unused monthly credits roll over for 3 months
An IP address goes to the same endpoint as a domain and returns the names behind it, with no second endpoint to call
A CSV with a domain column checks a whole list, on the same balance that pays for phone, email and IP checks

What it costs

From $4.00

per 1,000 DNS lookups; $9.90 on Starter

Where HackerTarget wins

Cheap at the low end: $10 a month billed annually covers 500 Tools API calls a day, about $0.67 per 1,000 calls if the whole allowance is used (arithmetic on the printed plan).
A free tier of 50 calls a day that needs no sign-up or key, and the same plain URL pattern for every tool.
A bundle for security work: the membership adds scanners (Nmap, OpenVAS, Zmap) and the other network tools on the page, such as reverse IP, host search, zone transfer and whois.
JSON output on request: output=json returns the A, AAAA, MX, NS, TXT, CNAME and SOA records as lists.

What it costs

$10 a month billed annually ($120) for 500 Tools API calls a day

Short answer

HackerTarget's memberships are priced by a daily allowance of Tools API calls, billed yearly: Starter is $10 a month ($120) for 500 calls a day, Pro $25 ($300) for 1,000 and Business $50 ($600) for 2,000, which is about $0.67 to $0.83 per 1,000 calls if the whole allowance is used every day, with 50 calls a day free and no sign-up. 1Lookup's DNS Lookup costs 2 credits per name with records, about $0.010 on Starter, or $9.90 per 1,000, so HackerTarget is far cheaper per call at full use. 1Lookup returns JSON with the mail provider and DNS host named, and bills nothing when a name has no records.

What replaces what

Here is which 1Lookup product matches each HackerTarget job.

HackerTarget counts one Tools API call for each request, against a daily allowance that resets. This is a different unit on 1Lookup: one domain or IP address, billed in credits from a monthly balance only when something is found, and nothing for a name that does not exist, a name with none of the eight types, an IP address with no reverse name or a lookup that times out.

DNS lookup (Tools API calls)
DNS Lookup API
A domain, web address or email address in; the A, AAAA, CNAME, MX, NS, TXT, CAA and SOA records, the mail provider and the DNS host out as JSON, in one call. An IP address in returns the names behind it, on the same endpoint. It has no port scans or other security tools.
2 credits per name with records, free when the name has no records

A real result

This is what one 1Lookup result looks like.

Send a domain or an IP address
POST a domain, a web address or an email address, or an IP address. It is cut down to the domain or the address. A single word, an internal name or a private address is refused with a clear error and costs nothing.
We ask DNS for all eight record types at once
1Lookup asks for the A, AAAA, CNAME, MX, NS, TXT, CAA and SOA records together, each under its own time limit, then reads the mail provider from the MX hosts and the DNS host from the name servers. An IP address is asked for its reverse name instead.
Get the records, flat and structured
The records arrive in one JSON payload, flat for a spreadsheet and structured for code. A name with records bills 2 credits, and a name with none bills nothing.

The evidence

Here is the evidence behind every number on this page.

Here are HackerTarget and 1Lookup side by side on the terms you check before you sign.

The terms that decide what a year actually costs, rather than what the first month does. “Not listed” means we could not verify it on either product’s published pages, not that the answer is nothing.

Term	1Lookup	HackerTarget
Minimum commitment	None. Monthly plans with no contract and no minimum volume; cancel any time	Starter, Pro and Business are billed annually at $120, $300 and $600 a year.
API access	Included on every plan and during the free trial; there is no tier that unlocks it	A free API with no key, and a member key (apikey parameter or X-API-Key header) for the paid allowance.
Rate limit	200 requests per 10 seconds for each API key on standard lookups and 1,000 requests a minute for each key on number type, HLR and MNP, and each account can make up to 1,000 requests a minute in total across all its keys; higher limits are available on request	2 requests a second, with HTTP 429 past it; 50 API calls a day on the free tier.
Support	Starter: Email Support; Growth: Priority Email & Chat Support; Professional: Chat + Live Meeting; Enterprise: Dedicated CSM	Not listed

This is the HackerTarget fine print worth reading twice.

Questions

People ask these questions before they switch from HackerTarget.

What is HackerTarget used for?

Security checks from a browser or a plain URL. Its membership adds scanners (Nmap, OpenVAS, Zmap) and network tools such as reverse IP, host search, zone transfer and whois. Its DNS lookup queries the A, AAAA, MX, NS, CNAME, TXT, PTR and SOA types behind one request, and returns text by default or JSON when you add output=json.

How does HackerTarget pricing work?

A free tier of 50 API calls a day with no sign-up or key, at up to 2 requests a second. Paid memberships are billed annually: Starter is $10 a month ($120 a year) for 500 Tools API calls a day, Pro $25 a month ($300) for 1,000, Business $50 a month ($600) for 2,000, and Enterprise starts at $100 a month for 7,500 or more a day. A 7-day money back guarantee covers every plan. Checked October 2026.

How much does 1Lookup charge for the same lookup?

2 credits per name with records, free when the name has no records. On the Starter plan ($99 a month for 20,000 credits) a name is about $0.010, which covers 10,000 DNS lookups a month and is $9.90 per 1,000. At the Enterprise end of the rate card it is about $0.004.

Is 1Lookup cheaper than HackerTarget per DNS lookup?

No. HackerTarget Starter works out to about $0.67 per 1,000 calls, and Pro and Business to about $0.83, against $9.90 per 1,000 on 1Lookup Starter and $4.00 on Enterprise. Those figures are arithmetic on a 30-day month and only hold if the whole daily allowance is used every day on calls to every tool, not only DNS.

What does each one return?

HackerTarget returns the A, AAAA, MX, NS, CNAME, TXT, PTR and SOA types, as plain text unless you ask for JSON, and has no CAA type. 1Lookup returns A, AAAA, CNAME, MX, NS, TXT, CAA and SOA as JSON, with two plain labels worked out from them: the mail provider, read from the MX hosts, and the DNS host, read from the name servers.

Where does HackerTarget beat 1Lookup?

On price per call at full use, on a free tier of 50 calls a day that needs no sign-up, and on the toolbox: scanners and network tools from the same membership, and the same plain URL pattern for every tool. 1Lookup's DNS Lookup does one thing, the DNS record read, and bills more per name.

How do the limits differ?

HackerTarget sets a daily cap on Tools API calls and returns HTTP 429 past 2 requests a second, so a large list has to be spread over days or moved to an Enterprise plan. 1Lookup draws from a monthly credit balance you can spend on any day, and unused monthly credits roll over for 3 months. A CSV with a domain or IP column runs a whole list in one job.

Can I look up an IP address too?

Yes on both. HackerTarget has a separate reversedns endpoint that counts as its own call. On 1Lookup an IP address goes to the same endpoint as a domain and returns the names published for it, free when it has none.

What is the best HackerTarget alternative?

If you want the lowest price per call, a free tier with no sign-up or a bundle of scanners and network tools, HackerTarget is the better value. If you want one JSON call that returns every record type with the mail provider and DNS host named, takes an IP address too and bills nothing when it finds nothing, 1Lookup's DNS Lookup bills 2 credits for every name with records.

Is HackerTarget worth it in 2026?

Yes if you do security work: the DNS lookup is one tool in a membership with scanners and network tests, and it costs less per call than 1Lookup. Plan for the yearly billing and the daily cap. If you look up a few thousand names a month to see where their mail and DNS are hosted, compare the per-name price of 1Lookup.
