Enrollment Baseline & Prior Verifications
Start a live check
Enter an email and mobile number above, then Send SMS or WhatsApp to send the link.
How a live check works
No app to install, about a minute end to end.
1
Enter the person's email and mobile, then send an SMS or WhatsApp link.
2
They tap it and send live video right from their mobile device.
3
Their live face appears next to every past visit on record — same person, session after session.
4
If it's them, you see it instantly. If it's someone else — like Kim, up in this session — you see that too.
5
You mark PASS or FAIL. The call is added to their history.
xChk records and shows the history; it never scans, scores, or face-matches. You decide, not the machine.

This is AI coaching detection. It listens for questions and answers them at the same time as your candidate. If the answers match they're likely getting help from AI.
You can also ask it questions yourself like "What are 10 good questions for a Devops candidate?" Give it a try.

API keys
Named keys help audit which integration called the API.

Test webhook sink: https://in.xchk.io/api/webhooks/test (logged on server)

API reference
Send an attestation request using an API key:
curl -s -X POST "https://in.xchk.io/api/attestations" -H "X-API-Key: your_key_here" -H "Content-Type: application/json" -d '{"user":"user@company.com","prompt":"Approve $5,000 payment to Vendor X","type":"t/f","ttl":3600}'
ttl is seconds until expiration (default 600, max 86400).
On response, results are POSTed to the key's webhook URL with payload: { event, attestation_id, target_email, prompt, response, ... } — signed with the key's webhook secret.
Results are also POSTed to the key's webhook URL. Configure Slack or Telegram under Profile → About me.
