Prospect search: find people by job title, seniority and company

Prospect Search builds a list of people who match the criteria you set, such as job title, seniority, location or employer. Use it to size an audience before you commit to it, and to pick the specific people worth revealing.

What it tells you

• Whether the search found anything, how many people are on the current page and the total number of matches behind your filters.
• How many of the rows returned have an email available to reveal.
• One preview record per person: first name, a masked surname, job title and employer.
• A flag on each row showing whether an email can be revealed for that person.
• Which product to use to reveal a row in full.

What you need to provide

No single input is required. Combine the filters that describe who you want:

• Job titles, seniority levels or free-text keywords.
• Locations for the person: countries, states or cities.
• Employer filters: specific company domains, or headcount bands.
• A page number to walk through results beyond the first page. It starts at 1.

What it costs

2 credits per search. Live per-product costs are shown on the Billing page in your dashboard.

How to run it

• In the dashboard: Prospect Search
• From your code: POST /v1/prospect-search, then see the Developer Hub at app.1lookup.io/developer-hub.

Good to know

• Search results are previews, not full records. Surnames come back masked, and there is no email on the row itself.
• To get the full record, pass the row's details to B2B Contact Append. That is the only call that charges the reveal price, so searching widely stays cheap and you pay for the reveals you choose.
• Results are point-in-time. People move roles and companies, so a list you pull today can drift, and a row marked email-available reflects the moment you searched.
• This returns personal data about identifiable people. Use it for legitimate business purposes only.
