Features

✓

All emails on a domain with names and roles

Each result returns the email, full name, department, seniority, and a 0–100 confidence score, so you get a ranked contact list rather than a bare address dump.

✓

Full company profile in the same response

The company object carries industry, employee size, revenue band, founding year, headquarters address, and social links — enough to qualify an account without a second lookup.

✓

Department and seniority filtering

Narrow the search to a department (sales, engineering, marketing) or a country so you retrieve only the contacts that matter to your campaign.

✓

Configurable result limit

Cap results at 10, 20, or 50 emails per call to control cost and payload size while still covering the accounts you care about.

Use cases

The domain search API — every email on a company domain

YepAPI's Domain Search API takes a company domain and returns the emails behind it, each attached to a real person with a name, department, seniority, and confidence score, alongside a company profile covering industry, size, revenue, and location. It is the fastest way to map an account's contacts and qualify it in the same call.

Pass a domain, optionally narrow by department or country, and cap the result count at 10, 20, or 50. At $0.03 a call with $5 of free credit and no minimums, it's a pay-as-you-go alternative to Hunter.io and Apollo that charges per search instead of per seat. Pair it with the Email Verifier to confirm deliverability before you send.
