How Candid sped up API development by 50% by going schema first

Candid, a medical billing API provider, has adopted Fern's schema-first API development approach. This method reduces the time developers spend on repetitive tasks such as writing boilerplate code and managing multiple sources of truth for their API. By using Fern, Candid generates Pydantic models, FastAPI routes, TypeScript clients, and auto-generated lines of backend and frontend codes. The company plans to use Fern for syncing API definitions with API docs and generating SDKs for customers in the future. This adoption has significantly improved efficiency and minimized errors caused by out-of-sync API components.
