REST APIs
HTTP APIs that connect frontends, agents, and model services.
Maturity level: L2 — Can Build
Six perspectives on REST APIs
Roadmap
Learn with Python before FastAPI and LLM endpoints.
Architecture
Contract between clients, agents, and backend services.
Company
Universal expectation for backend and AI engineer roles.
Projects
OpenAPI spec for every service you build.
Interview
API design and production concerns.
Career
Foundation for shipping AI products.
What & Why
What: RESTful HTTP APIs with JSON payloads, status codes, and authentication.
Why: AI features ship as APIs — even before FastAPI, you need HTTP fundamentals.
Build this
Design and document a versioned REST API for a prediction service with OpenAPI.
Production reality
- ! Breaking changes
- ! Auth leaks
- ! Pagination bugs
- ! Timeout cascades
Interview preparation
- Design a REST API for batch inference
- Idempotency for POST requests
Explore REST APIs in the interactive universe or train with live cohorts.
