We have just added the Email API — a complete email-intelligence suite of 18 endpoints under `/v1/email/*`. Find every email on a company domain, find a specific person's email from their name, verify deliverability with real SMTP and MX checks, enrich an email into a full person or company profile, discover email patterns, look up phone numbers, and more. Every endpoint returns clean, simplified JSON under the same `{ ok, data }` envelope, uses the same `yep_sk_` key, and is priced per call from $0.01 — no subscription, no seat fees.

Endpoints in this release
What you can build with it
Enrich your signups and leads the moment they arrive: turn an email into a name, role, company, and social profiles, or a company domain into industry, size, revenue, and tech stack. Build a prospecting tool that finds verified emails from names, or a data-quality step that verifies deliverability before you send. Score and route inbound leads, dedupe and complete your CRM, or power a cold-outreach workflow end to end — find the email, verify it, enrich the person, and pull a phone number, all from one key.
How to call it
Every endpoint is a POST under `/v1/email/*` with a small JSON body. Find an email from a name and domain:
curl -X POST https://api.yepapi.com/v1/email/finder \
-H "x-api-key: $YEPAPI_KEY" \
-H "Content-Type: application/json" \
-d '{
"domain": "stripe.com",
"first_name": "Patrick",
"last_name": "Collison"
}'Pricing
