Welcome to BlitzAPI! In this guide, we will perform a simple but powerful task: finding a verified professional email from a LinkedIn profile URL.
Prerequisites: You need an API Key. You can grab one from your BlitzAPI Dashboard.
1

Choose your client

BlitzAPI is a standard REST API, so you can use it with any language.For Python or JavaScript/TypeScript, the fastest path is the official SDK — it handles auth, retries, rate limiting, and pagination for you. Prefer cURL for a quick terminal test, or call the REST API directly from any other language.
2

Install the SDK

Skip this step if you’re using cURL.
See the SDK guides for the full API surface.
3

Send the request

We will use the POST /v2/enrichment/email endpoint. Replace YOUR_API_KEY with your actual key, or set it as the BLITZ_API_KEY environment variable (the SDKs read it automatically).
4

Check the response

You should receive a JSON object containing the verified email and its status.
Response Fields:
All paid plans include unlimited requests — included in your flat monthly subscription.

What just happened?

  1. Authentication: You passed your key via the x-api-key header.
  2. Identity Matching: BlitzAPI matched the LinkedIn profile URL against our verified B2B dataset.
  3. Verification: We validated email deliverability (SMTP handshake) before returning it.
