The API Podcast with Fexingo: REST, GraphQL, and Modern Web APIs

Every week, Lucas and Luna sit down at a developer-focused office workstation to trace how applications actually talk to each other — not the hype, but the design decisions, trade-offs, and real-world failures that shape modern API architecture. Lucas, with a journalist's precision, lays out why a team chose REST over GraphQL for a payments pipeline handling 50,000 requests per second, or how a poorly designed endpoint caused a cascade failure in a major ride-hailing service. Luna, the engaged interlocutor, pushes back: when does schema flexibility become a liability? How do versioning strategies survive a decade of production use? Together, they dissect public postmortems, API design docs, and developer surveys — not to sell a tool, but to understand the engineering logic behind each choice. This show is for backend engineers, API product managers, and technical leads who need to decide, not just follow the trend. Expect no demos, no code walkthroughs — just two smart people reasoning
