Step-by-Step Production REST Tutorials
Click any lesson below to start learning. Real production blueprints with zero fluff.
Level 1: Foundations
What is a REST API? The Architectural Blueprint
Demystifying Roy Fielding's 6 architectural constraints, the request-response cycle, and why most REST APIs are actually HTTP RPC.
HTTP Methods, Status Codes & Query Parameters Masterclass
Master the exact rules for GET, POST, PUT, PATCH, DELETE. Explore the definitive PUT vs POST breakdown, CRUD mechanics, and production HTTP GET query string design.
Designing Your First Production CRUD API
A complete step-by-step walkthrough of designing clean URI hierarchies, validation contracts, status codes, and consistent response envelopes.
Level 2: Production Scale
Cursor vs Offset Pagination: Scalability Benchmarks
Why LIMIT OFFSET kills database query planners at scale, and how to build high-performance cursor pagination with opaque tokens.
API Authentication: Why Basic Auth is Deprecated & Modern Production Patterns
Authentication is mission-critical. Learn why HTTP Basic Auth is dangerous in production, how to implement hashed API keys, stateless JWT rotation, and OAuth 2.1 with PKCE.
Rate Limiting, Throttling & Circuit Breakers
How production APIs protect backend databases against spikes and DDoS. Comparing Token Bucket, Leaky Bucket, and Fixed Window algorithms with RFC 6585 headers.
Level 3: Distributed & AI Systems
Designing REST APIs for Autonomous AI Agents
How to engineer endpoints tailored for LLM tool calling: strict JSON Schema validation, deterministic schemas, RFC 9457 self-correction, and streaming SSE tokens.
Distributed Idempotency Keys: The Stripe Architecture
How to prevent double-charges and race conditions on retried mutative requests using atomic Redis locks and response caching.
Designing REST APIs for Autonomous AI Agents
How to engineer endpoints tailored for LLM tool calling: strict JSON Schema v7 validation, deterministic schemas, and streaming SSE tokens.
