IPQualityScore Complicates Fraud Detection.1Lookup Simplifies Everything.
IPQualityScore offers fraud detection across many services, but with complex pricing and multiple APIs. 1Lookup delivers integrated IP intelligence with unified validation for phone, email, and IP in one platform. One API and one credit system cover all three checks, so there is no menu of separate services to price out.
Unified Intelligence Platform
While IPQualityScore requires separate API calls for IP, email, and phone validation, 1Lookup integrates all validation types in a unified platform. Get combined intelligence with simpler integration and consistent data across all validation types.
Superior Performance
Query IP reputation in real time over a REST API. Our globally distributed edge network and optimized algorithms deliver faster results for better user experience and higher conversion rates.
Integrated Platform vs. Service Collection
Why unified intelligence wins for multi-service validation
| Feature | 1Lookup | IPQualityScore (IPQS) | Winner |
|---|---|---|---|
Fraud Detection Both offer advanced fraud detection | Integrated AI fraud scoring | Broad fraud scoring | |
Pricing Model Transparent vs. complex subscription tiers | Simple per-query pricing | Tiered subscription pricing | |
Service Breadth Focused vs. broad platform | IP + Phone + Email validation | IP + Email + Phone + many services | |
VPN/Proxy Detection Both offer strong anonymization detection | Advanced VPN detection | Extensive proxy detection | |
Real-time Updates More frequent threat intelligence updates | Continuous real-time feeds | Regular database updates | |
API Complexity Simpler integration vs. extensive options | Simple unified API | Multiple API endpoints |
Every lookup returns a risk signal, not just valid or invalid
A number can be perfectly well-formed and still be a burner, a VOIP line opened this morning, or a number other businesses have already reported. 1Lookup returns a risk score, a spam indicator and line type on the same call as the validation, so the decision to block, challenge or allow can be made in one request.
Real-time Risk Scoring
Instant fraud probability assessment for every number
Pattern Recognition
Detect suspicious behavior patterns across millions of numbers

Example response
One credit balance
Every product below draws from the same credits, at $0.00200–$0.00495 per credit depending on plan.
- Phone validation1 credit
- Email verification1 credit
- IP intelligence1 credit
- Spam and risk score1 credit
Buy credits once, spend them on whatever you need to check
Most validation tools sell one channel, so a team checking phones, emails and IPs ends up with three vendors, three invoices and three unused balances. 1Lookup bills all of them from a single credit pool on a monthly plan, with no contract, and leftover credits carry into the next quarter instead of expiring at midnight.
Phone, email and IP on one API
One key, one balance, one integration
Phone data refreshed daily
From FCC and carrier sources
No contract
Monthly plans, with three-month credit rollover
A full line profile, not a status code
The same call returns HLR data, subscriber status, porting history, network type and roaming state. That is the difference between knowing a number is formatted correctly and knowing whether a message sent to it will arrive.

Simple Migration from IPQualityScore
const ipResult = await fetch(
'https://ipqualityscore.com/api/json/ip/{key}/{ip}'
);
const emailResult = await fetch(
'https://ipqualityscore.com/api/json/email/{key}/{email}'
);
// Separate integrations for each service
`https://api.1lookup.io/v1/validate`,
{
method: 'POST',
headers: {'X-API-Key': key},
body: JSON.stringify({ip, email, phone})
}
);
What migrating from IPQualityScore actually involves
Both are REST APIs returning JSON, so the move is a URL, a key and a field mapping rather than a rewrite. The call above is the real shape of each request. Where the work usually goes is the response: our field names differ, and anything you were deriving from a status code may already be a field you can read directly.
One endpoint per channel
Phone, email and IP, same key and same balance
Email Support to Dedicated CSM
Support level rises with the plan, not with a separate fee

IPQualityScore vs 1Lookup FAQ
Common questions about IPQualityScore and switching to 1Lookup
What is IPQualityScore?
IPQualityScore (IPQS) is a fraud prevention and detection platform used to flag risky traffic, fake accounts, and suspicious transactions. It provides IP intelligence, bot and proxy/VPN detection, email verification, phone validation, device fingerprinting, and reverse lookups through a suite of APIs. Teams typically use it for chargeback prevention, account-fraud screening, and traffic quality analysis.
How much does IPQualityScore cost?
IPQualityScore uses credit-based, volume-tiered pricing rather than a single flat rate, and credit consumption varies by endpoint and the data you request. As of publication, IPQS offers a free tier (around 1,000 lookups per month) and paid plans that start around $99/month, with enterprise pricing available through their sales team. Because each service and feature can draw a different amount of credit, your actual cost depends on which checks you run and at what volume.
What is the best IPQualityScore alternative?
The best alternative depends on your use case, but 1Lookup is a strong option for teams that want phone, email, and IP verification unified in a single API and one universal credit system. Instead of pricing out and integrating separate services, you run all three checks through one integration, with data refreshed daily from FCC and carrier sources. A 7-day free trial lets you compare results against IPQS before you commit.
How is 1Lookup different from IPQualityScore?
Both platforms offer capable fraud and IP intelligence, and IPQS is strong across a broad menu of fraud services. 1Lookup’s main difference is unification: phone, email, and IP validation run through one API and one universal credit system, rather than separate endpoints and per-service pricing. 1Lookup also covers carrier/HLR lookup, reverse lookup, and IP/fraud intelligence, with its data updated daily.
Can I try 1Lookup for free?
Yes. 1Lookup offers a 7-day free trial so you can test phone, email, and IP verification with your own data before paying. You can sign up and start validating through the single API and shared credit system right away, which makes it easy to benchmark 1Lookup against IPQualityScore.
Is IPQualityScore worth it in 2026?
IPQualityScore is worth it when fraud prevention, not just list cleaning, is the job: one lookup pool covers IP and proxy reputation, email validation, phone validation, URL scanning, and device fingerprinting, with a free plan of 1,000 lookups per month and no contracts. The catch is cost per check and gating: $99/mo buys only 5,000 lookups and $499/mo only 10,000, tier prices are advertised as starting points rather than fixed rates, and lower plans carry hard daily caps (250 lookups per day on Startup). Capabilities like device fingerprinting and Fraud Fusion are Enterprise-only at custom pricing. For straightforward validation volume across phone, email, and IP, a multi-channel per-lookup API like 1Lookup is usually the cheaper shape.

Before you sign: IPQualityScore and 1Lookup on the operational terms
The terms that decide what a year actually costs, rather than what the first month does. A blank means we could not verify it on either product’s published pages, not that the answer is nothing.
| Term | 1Lookup | IPQualityScore |
|---|---|---|
| Minimum commitment | None. Monthly plans with no contract and no minimum volume; cancel any time | No contract or long-term commitment; cancel, upgrade or downgrade at any time. However, "Each plan requires a minimum monthly commitment," and annual plan options are not published and require contacting IPQS. |
| API access | Included on every plan and during the free trial; there is no tier that unlocks it | API access is on every plan including Free, which comes with 1,000 lookups/month and a free API key. Specific API capabilities are tier-gated: the phone validation docs state "User & Transaction Scoring" requires a Premium plan or greater. |
| Rate limit | 1,000 requests per minute on standard accounts, with higher limits available on request | 20 lookups per second, first appearing on the SMB Basic plan ($499/month). Free is capped at 35 lookups/day and Startup at 250 lookups/day. Enterprise gets unspecified "higher rate limits." No per-second figure is published for Free, Startup or SMB+. |
| Uptime SLA | — | 99.5% SLA guarantee starting on the SMB+ plan ($999/month); 99.9% SLA guarantee on Enterprise. Free, Startup and SMB Basic have no stated SLA, only "Reliable Uptime." |
| Compliance | — | ISO, SOC, GDPR and FIDO member badges are displayed site-wide in the footer. The specific certification levels (for example SOC 2 Type II or ISO 27001) are not spelled out on the pages I loaded. |
| Support | Starter: Email Support; Growth: Priority Email & Chat Support; Professional: Chat + Live Meeting; Enterprise: Dedicated CSM | Phone (800) 713-2618 and a demo scheduling form are published for all visitors. "Enterprise Support" with an integration specialist and 7-days-a-week replies is listed as an Enterprise-plan feature. |
IPQualityScore fine print worth reading twice
Published terms that change what IPQualityScore costs or what you can do with it. Each one links to the IPQualityScore page it was read on, because a claim about somebody else’s contract should be checkable in one click.
Paid plan prices are shown as "As low as: $99 / Month," "As low as: $499 / Month" and "As low as: $999 / Month," so the displayed figures are floors rather than fixed prices.
