Getting Started

The BluAuto API lets you verify an email address or find one from a name and a company domain. Everything runs behind a single API key.

Base URL

All requests go to:

https://app.bluauto.io

What you can do

Endpoint	What it does
POST /api/v1/verify	Check whether a specific email address exists and is safe to send to.
POST /api/v1/find	Find a person's email from their name and company domain.

Your first request

Grab your API key (see Authentication), then verify an email in one call:

curl https://app.bluauto.io/api/v1/verify \
  -X POST \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{"email":"john@acme.com"}'

You get back JSON with a status, a human label, and the mail provider mx:

{ "status": "valid", "label": "Found", "mx": "Microsoft" }

That is the whole flow. The pages under API Reference cover each endpoint, every response value, and what they mean.

How verification works

• Microsoft domains are checked through Microsoft's own login system, because Microsoft mail servers deliberately give misleading answers to standard checks.
• Everything else is checked over SMTP, which stays reliable for Google and self-hosted mail.

You do not need to know which path a domain takes. The API picks the right one automatically and returns a single, consistent result.
