Verify humans. Reuse identity.

Valyd gives developers two straightforward ways to add trusted human verification: check that someone is a live, unique human with a quick redirect to Valyd’s verification page, or let users connect their Valyd identity and reuse verified information — running any extra checks your app needs.

Two products

Pick the outcome you need — each card takes you straight to working code.

Determine whether someone is live and unique with your API key — start a session, redirect to Valyd’s verification page, read the verdict. No user accounts.

Unique Human API

Users connect their Valyd identity, share verified information they already hold, and complete any additional checks your app requires — KYC, licenses, face match, and more.

Reusable Verification

Common tasks

Is this a live human in front of the camera? Valyd captures and scores it; the verdict comes back to you.

Check liveness

Standard OpenID Connect — a two-line button connects a user’s verified identity (and can double as sign-in).

Connect with Valyd

Configure the checks your app needs, start a session, read the decision.

Run a verification workflow

Invite teammates with roles, share apps, and bill one account.

Organizations & teams

The API Playground runs the real flow against demo users.

Try it live

The Valyd MCP server turns verification into agent tools.

Build with AI agents

Get running in 3 steps

Create an app, copy your credentials, call the API — start from the result you need.

  1. 1

    Create an app & copy credentials

    An app in the developer portal gives you an API key for the Unique Human API and OIDC client credentials for Connect with Valyd.

  2. 2

    Call the API or connect the user

    Call the Unique Human API with just your API key, or use Connect with Valyd and run a configured verification workflow for the user.

  3. 3

    Read the result or decision

    Unique Human API results return directly to your call. Workflow decisions arrive via statuses and webhooks, with passed proofs saved to the user’s Valyd ID.
