Build CAIRL into your flow.
APIs, OAuth, hosted verification, and webhooks for builders adding people-centered identity checks to business, platform, community, and government workflows.
APIs
Create verification sessions and retrieve verified claims.
OAuth
Let people authorize relevant claim sharing through supported flows.
Hosted verification
Send users through a CAIRL-hosted flow when speed matters.
Partner handoff
Route implementation, resale, or advisory motions without calling every customer a partner.
Sign in with CAIRL
Add Sign in with CAIRL to an application that already runs an identity platform. It is a standard OpenID Connect integration: discovery, PKCE, and an ID token that carries a pairwise identifier and nothing else. No name, email address, or verification status is shared. Walkthroughs cover Clerk and Auth0.
