At a glance
Here is where 1Lookup wins against ZoomInfo, and where ZoomInfo still wins.
1Lookup sells the core B2B data jobs as self-serve API lookups, each priced before you run it, with no annual contract and no procurement cycle. ZoomInfo's core platform is sold through annual, seat-based contracts and a sales process.
1lookupWhere 1Lookup wins- Self-serve from signup to API call: no sales cycle, no annual contract, no seat minimums
- Search is nearly free (2 credits) and enrichment is success-billed: a no-match costs nothing
- Prospecting, firmographics, and contact reveal share one credit balance with validation products
- Per-lookup costs are shown in the dashboard before you run anything
What it costs
From $149.92
per 1,000 contact matches; $371.25 on Starter
ZoomInfoWhere ZoomInfo wins- Category-leading B2B database scale, per ZoomInfo's own live pages: 500M+ global contacts and 110M+ companies (free-trial page), 200M+ verified business email addresses and 120M+ direct-dial phone numbers (pricing guide), plus technographics and buying-intent signals
- Full go-to-market platform around the data - Copilot AI, WebSights website-visitor identification, Streaming Intent, Engage sales engagement, and deep CRM/SEP integrations - not just a lookup API
- API access is included in all ZoomInfo Copilot plans (announced July 24, 2025), and the Enterprise API surface is mature: Search & Enrich, Scale & Subscribe, WebSights, and Compliance API families with OAuth (PKCE and client-credentials) auth and Builder/Standard/Scaling rate-limit packages
- New self-serve on-ramp via GTM AI by ZoomInfo: free MCP/API/CLI access, free search/lookup/find-similar calls, pay-as-you-go from $20 with no contract or seat fees, and enriched records are not re-charged for 12 months
- Genuinely free permanent tier (ZoomInfo Lite, 10-25 credits/mo) plus a typical 7-day no-credit-card trial of the full platform
What it costs
Core platform: not publicly listed - every contract is sales-quoted
Short answer
ZoomInfo's core platform is sold through annual, seat-based contracts with pricing quoted by its sales team rather than published; a newer self-serve tier covers pay-as-you-go record enrichment. 1Lookup covers the core data jobs (finding prospects by title and employer, revealing verified work emails, and enriching companies with firmographics) as flat-priced, self-serve API lookups on universal credits, with per-search costs shown before you run anything.

Side by side
Both products are measured on the same criteria, using ZoomInfo's own published numbers.
| Criteria | 1lookup | ZoomInfo |
|---|---|---|
| Contact-data coverage | EmailPhoneIP | EmailPhoneIP |
| Pricing model | Monthly plans with universal credits; core phone, email and IP lookups cost 1 credit, enrichment and intelligence products cost more | Two-track. Core ZoomInfo platform (Copilot plans): sales-quoted annual contracts scoped on team size, credit volume, features (intent data, technographics, WebSights), integrations/API access, and term - no published prices; ZoomInfo's own pricing guide states plans are "billed annually, not monthly" and "there is no standard monthly billing option", with add-ons (Streaming Intent, Engage, international data, extra seats, API/MCP) priced separately. Self-serve "GTM AI by ZoomInfo": consumption-based pay-as-you-go with two credit types - data credits (1 credit = one company, contact, or intent record enriched or exported) and AI credits (agent/research tasks) - "one tier, no contract, no seat fees". |
| Starting price | $99/mo for 20,000 credits. At 75 credits each (B2B Contact Append), that is $371.25 per 1,000 contact matches on Starter, down to $149.92 on Enterprise. | Core platform: not publicly listed - every contract is sales-quoted. Self-serve GTM AI by ZoomInfo: pay-as-you-go top-ups starting at $20; data credits cost $0.45/record at the base tier, $0.38 at the $1,000 spend tier and $0.25 at 100,000 credits (a limited-time offer takes 70% off a first data credit purchase), AI credits $0.05/credit flat. |
| Free option | Free single lookups via the online tools at 1lookup.io/tools, no account required | ZoomInfo Lite: permanent free tier, no credit card, no expiration - 10 credits/mo (25/mo with Community Edition contribution), advanced contact/company search, contact exports, Chrome extension (ReachOut), WebSights Lite (up to 10 visitor reveals/day), email sending, HubSpot CRM integration. GTM AI: free search/lookup/find-similar, and free-tier MCP, API, and CLI access (5 req/sec, 5 apps). |
| Free trial | 7-day free trial on every plan: $5 of credits on Starter, $20 on Growth, Professional, and Enterprise, with no payment today | Typically a 7-day free trial of the core platform - no credit card required, ends automatically; includes contact/company search, intent signals, and email outreach "with usage limits". ZoomInfo notes trial length/terms vary by promotion, company size, industry, and package. |
| Do credits expire? | Unused monthly credits roll over for 3 months; separately purchased credits last 1 year | Core platform: expiration terms are not publicly documented and are contract-specific - ZoomInfo's own pricing guide tells buyers to "ask whether unused credits roll over to the next period or expire". |

The evidence
Here is the evidence behind every number on this page.
Here are ZoomInfo 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 | ZoomInfo |
|---|---|---|
| Minimum commitment | None. Monthly plans with no contract and no minimum volume; cancel any time | Pay-as-you-go tier is stated as 'One tier, no contract, no seat fees.' Enterprise starting price is 'Custom' and routes to 'Talk to sales.' No contract terms are published for the seat-based ZoomInfo sales platform. |
| Cost per extra seat | Not listed | No seat fees on the pay-as-you-go GTM AI tier ('no seat fees'). Per-seat pricing for the core ZoomInfo sales platform is not published on any page that would load. |
| Going over your quota | Not listed | No overage billing on pay-as-you-go. Past the balance: 'Free tools - search, lookup, find similar, recommended contacts - keep working. Enrichment and AI research pause until you top up.' Top-ups start at $20 with no sales call. |
| API access | Included on every plan and during the free trial; there is no tier that unlocks it | MCP, API and CLI access are included on the free GTM AI tier at signup. Separately, the docs state 'Your subscription determines which API scopes and endpoints you can access.' |
| 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 | Builder 5 req/s (10,800/hour, 129,600/day); Standard 25 req/s (54,000/hour, 648,000/day); Scaling 35 req/s (75,600/hour, 907,200/day). Free GTM AI tier is listed as '5 req/sec · 5 apps'; Enterprise rate limits are 'Custom'. |
| Compliance | Not listed | ISO 27001, ISO 27701, SOC 2 Type II, TRUSTe (named on https://www.zoominfo.com/about/security) |
| Support | Starter: Email Support; Growth: Priority Email & Chat Support; Professional: Chat + Live Meeting; Enterprise: Dedicated CSM | 'SLA-backed support' and 'Forward-deployed engineers' are listed in the Free-vs-Enterprise comparison table as Enterprise-only; both rows show '-' for the Free tier. |
This is the ZoomInfo fine print worth reading twice.
Published terms that change what ZoomInfo costs or what you can do with it. Each one links to the ZoomInfo page it was read on, because a claim about somebody else’s contract should be checkable in one click.
The 70% discount is a limited-time offer for new signups and covers a first data credit purchase only; after it, data credits cost $0.45 each at the base tier and $0.38 at the $1,000 spend tier.

Who it is for
Pick 1Lookup or stay with ZoomInfo depending on the job in front of you.
1lookupChoose 1Lookup if
you want self-serve, pay-as-you-go prospecting and enrichment: search cheaply, reveal only the contacts you need, and never sign an annual seat contract.
ZoomInfoConsider ZoomInfo instead if
you are an enterprise revenue team that wants the deepest US B2B database plus intent data, org charts, and a sales-led platform relationship.
Questions
People ask these questions before they switch from ZoomInfo.
Is there a ZoomInfo alternative without an annual contract?
Yes. 1Lookup is fully self-serve: monthly plans with universal credits, a 7-day free trial, and per-lookup pricing displayed before every call. Searching costs 2 credits regardless of result count, and enrichments are success-billed, so a no-match costs nothing.
Does ZoomInfo publish its pricing?
Not for its core platform: those contracts are quoted through sales and depend on seats, credits, and modules. ZoomInfo has also introduced a self-serve, consumption-based tier with published per-record rates for enrichment and exports. The verified details for both tracks are in the comparison table on this page.
How is 1Lookup's B2B data delivered?
Prospect Search, Account Search, B2B Contact Append, and Company Firmographics are per-call API lookups, with 1Lookup's normalization (seniority levels, confidence ratings, SIC/NAICS codes) applied to every result.
When should you pick 1Lookup over ZoomInfo?
When you want B2B data without a procurement cycle: prospect search, verified work emails and company firmographics as self-serve API lookups, each priced before you run it, on a credit balance shared with phone, email and IP checks. ZoomInfo is built for enterprise revenue teams that want its US contact coverage plus intent signals, org charts and workflows, and that have the budget cycle to buy an annual contract.
Can I try the data before paying?
Every plan starts with a 7-day free trial that includes trial credits. Prospect searches cost 2 credits and show email availability per row up front, so you can evaluate coverage on your actual ICP for a few cents before committing to anything.
Is ZoomInfo worth it in 2026?
For enterprise sales teams that live in US and Canada B2B data and use intent signals, org charts, and the integrations daily, ZoomInfo's depth is still the benchmark and can justify a five-figure contract. For teams that mainly verify contacts or run occasional lookups, the sales-quoted annual contracts and fast-burning credit system are hard to justify, and cost plus renewals are reviewers' loudest complaints. Lighter usage is covered by ZoomInfo's own self-serve GTM AI tier from $20 pay-as-you-go, or by per-lookup APIs like 1Lookup.
