**APIs profiled:** 2

Passbase was a developer-first identity verification (KYC) platform founded in Berlin and San Francisco that let companies verify users in seconds through facial comparison, liveness detection, and authenticity checks on government-issued IDs from 190+ countries. It shipped mobile and web client SDKs plus a server-side Verifications API (v2) for reading verified identities, their resources and data points, and project settings, with webhooks for verification lifecycle events. Passbase was acquired by Parallel Markets in March 2023; api.passbase.com and docs.passbase.com are no longer live, and this API Evangelist profile captures the last-published API surface reconstructed from the company's official OpenAPI-generated SDKs. Backed by Cowboy Ventures and Seedcamp.
