Clarity in API Design

A good API isn’t just a set of working endpoints. The developer consuming it needs to easily predict what to expect. That makes naming, response format, and the error model as important as performance.

Name Resources Consistently

Endpoints should represent resources whenever possible.

GET /posts
GET /posts/:id
POST /posts
PATCH /posts/:id
DELETE /posts/:id

This structure is predictable. Adding new endpoints by following the same pattern stays easy.

Errors Are Part of the Design Too

Error responses should be as consistent as normal ones.

{
  "code": "POST_NOT_FOUND",
  "message": "Post not found."
}

Conclusion

The goal of API design is not to surprise. The fewer special cases, the smoother the integration.
