AEPs: Because Your API Deserves a Standard, Not a Mess
Google's open-source AEPs repository aims to bring sanity to API design—think PEP for APIs, minus the drama.

Ever tried to integrate two microservices from different teams and felt like you're negotiating a peace treaty? Well, Google's got your back with AEPs (API Enhancement Proposals).
AEPs is an open-source repository that collects best practices for designing APIs. It's like Python's PEP but for REST and gRPC. Instead of reinventing the wheel (and making it square), you can check AEPs to learn how to name endpoints, which status codes to use, and how to avoid common pitfalls.
The cool part? AEPs are living documents with discussions. You can submit your own proposal if your specific pain point isn't covered. Just be prepared for a code review that might take longer than your sprint—but hey, better than rewriting half your backend later.
What's Inside?
- Naming conventions: no more guessing between
usersanduser-profiles. - Standard errors: 404, 409, 429—all predefined, so you don't invent custom codes.
- Pagination: finally, a unified approach to cursor-based and offset-based pagination.
- Versioning: spoiler: v1, v2 isn't always the answer.
Sure, AEPs won't fix a team that loves hardcoding magic numbers. But for startups and mature projects, it's a solid foundation to avoid bikeshedding and keep your API consistent.
Studio METABYTE's take: At METABYTE, we dig standards—especially when they save us from endless debates about endpoint naming. AEPs help you focus on business logic instead of reinventing API patterns. Though, we admit, sometimes we still use magic numbers—but only when no one's looking.
