Question 1

Website audience intelligence: who visits a site

Accepted Answer

Audience Intelligence profiles the people who visit a website: where they are, who they are, where they came from and where they go next. You pick one report per call and get its rows back. Use it to research a market, a media buy or a competitor's audience.

What it tells you

You choose which of these reports you want:

Traffic by country, with each country's share of traffic and its bounce rate.
The age and sex breakdown of the audience.
The income breakdown of the audience.
Where the site's traffic comes from, and where visitors go next after leaving.
A summary view of the site overall.

Every report also names itself in plain words and tells you how many rows came back.

What you need to provide

The website domain you want profiled, for example "nytimes.com".
Optionally, which report you want: summary, geo, age_sex, income, sources or destinations. It defaults to summary.

What it costs

86 credits per report. Each call returns one report, so ask for the report you need rather than paying for the whole profile. Live per-product costs are shown on the Billing page in your dashboard.

How to run it

In the dashboard: Audience Intelligence
From your code: POST /v1/audience-intelligence, then see the Developer Hub at app.1lookup.io/developer-hub.

Good to know

The figures are estimates of a site's audience, not that site's own analytics, so read them as a shape rather than an exact headcount.
Results are point-in-time. Audiences shift,

Question 2

TikTok audience demographics: where a creator's followers are

Accepted Answer

See which countries a TikTok account's followers come from, and what share of the audience each country makes up. Use it before paying for a creator partnership, or to check that an account's audience sits in the markets you sell to.

What it tells you

The list of countries the account's followers are in.
The share of the audience in each country, as a percentage.
The two-letter country code alongside each country name.
Which single country is the largest slice of the audience.
Whether the handle was matched at all.

What you need to provide

The TikTok handle, with or without the @, or the full profile URL.

What it costs

40 credits per lookup. This one is success-based: you are charged 0 credits on a no-match. Live per-product costs are shown on the Billing page in your dashboard.

How to run it

In the dashboard: TikTok Audience Demographics
From your code: POST /v1/audience-demographics, then see the Developer Hub at app.1lookup.io/developer-hub.

Good to know

TikTok only. Social Profile Check gives you follower counts and profile detail on the platforms it covers, though not this country breakdown.
Results are point-in-time. Audiences shift as an account grows, so re-run rather than reusing an old result in a new decision.
You get a country-level breakdown, not age, gender or interests.
Not every handle returns a breakdown. When nothing matches, the lookup costs you 0 credits, so testing a handle is cheap.
This is aggregate audie

Question 3

Mobile finder: get a personal mobile from a profile or work email

Accepted Answer

Mobile finder takes what you already know about a professional, such as their profile URL or work email, and returns their personal mobile number. Use it when you can reach someone by email but need a direct number.

What it tells you

Whether a mobile number was found for that person.
The personal mobile number itself.
Which identifier produced the match, such as the profile URL and the email address used.
A risk score, a risk level and a confidence level on the result.
A suggested next action and a short plain-English message about the outcome.

What you need to provide

Send any combination of these three. At least one is required, and sending more identifiers raises the match rate.

A professional profile URL, for example a LinkedIn profile.
A work email address for the person.
A personal email address for the person.

What it costs

40 credits per lookup. This one is success-based: you are charged 0 credits when no number is found. Live per-product costs are shown on the Billing page in your dashboard.

How to run it

In the dashboard: Mobile Finder
From your code: POST /v1/mobile-finder, then see the Developer Hub at app.1lookup.io/developer-hub.

Good to know

One identifier will run, but it is the weakest input. If you have both a profile URL and a work email, send both.
A no-match result is a real outcome, not an error. It means no mobile was found for the identifiers you sent.
Results are point-in-time. People change mobile n

Question 4

Company firmographics: size, revenue, industry and tech stack

Accepted Answer

Company Firmographics turns a company domain into the business facts behind it: what the company does, how big it is and what it runs on. Use it to score inbound leads, route accounts to the right team or fill gaps in your CRM records.

What it tells you

Whether the domain matched a company at all, and the company name on record.
The industry the company sits in, the country it is based in and the year it was founded.
Headcount, both as a number and as a size band, plus annual revenue.
Standard industry codes (SIC and NAICS) you can use for your own segmentation.
How many technologies the company uses, so you can gauge how built-out its stack is.
Growth signals: headcount change over the past 12 months, and headcount broken out by department.

What you need to provide

One input: the company's domain, for example "shopify.com".

What it costs

75 credits per lookup. This one is success-based: you are charged 0 credits when the company is not matched. Live per-product costs are shown on the Billing page in your dashboard.

How to run it

In the dashboard: Company Firmographics
From your code: POST /v1/company-firmographics, then see the Developer Hub at app.1lookup.io/developer-hub.

Good to know

Results are point-in-time. Headcount, revenue and tech stack all move, so re-check a record before you act on an old result.
The only accepted input is a domain, so you need to resolve a company name to its domain before you call this.
Because a

Question 5

Which products exist, and what works where

Accepted Answer

The product families

Phone: phone/number validation, HLR lookup (live network check), ported-number (MNP) lookup, number type, mobile finder, spam and risk score, DNC and compliance check, reverse phone lookup (which includes caller-name data where available), and number monitoring (watch lists re-checked on a schedule).
Email: email verification (deliverability), email enrichment, reverse email lookup.
IP: IP/network lookup, reverse IP.
Web and identity: website scraper, website contacts scraper, search intent lookup, skip tracing, job-change monitoring.

The full, current product list is in the catalog: app.1lookup.io/catalog. Per-product credit costs are on the Billing page in the dashboard.

Coverage, stated honestly

Coverage differs by product:

US and Canada are our strongest coverage across the phone products, and reverse phone/email/IP lookup and skip tracing are US-focused.
HLR, ported-number, and number-type lookups work internationally: they query live carrier networks. International phone spam/risk scoring also exists.
DNC/compliance checking is a US product.

We do not publish country counts or blanket accuracy percentages, because honest coverage varies by product and country. The reliable way to know whether 1Lookup fits your country and use case: run a sample of your own data on a trial. Volume buyer?

Question 6

Privacy and security

Accepted Answer

Your account's privacy in the chat

Support (including Jake, our AI agent) will never confirm or deny to anyone whether an email address has a 1Lookup account. Before any account details are shared in chat, we verify you with the email on the account plus the last 4 digits of the card on file. That is the most we will ever ask for: never a password, never a full card number, never a full API key.

If you paste a secret (an API key, a password) into any chat by accident, treat it as exposed: rotate the API key on the API Keys page or change the password.

Your data

We store your account details and your lookup history (inputs and results) so you can re-download results. Data is stored encrypted on AWS.
Want your data deleted? Write to us in the chat or at support@1lookup.io; deletion requests are honored, except records we must keep for legal and billing reasons.
We do not name the individual upstream sources behind products; data comes from licensed commercial sources and live network checks.

Acceptable use

1Lookup is for legitimate business contact and verification purposes. Using it to stalk, harass, or defraud people is against the terms and gets an account closed.
