+# Tasks: Add /hello Endpoint to API Service
+
+## Task Order (dependency sequence)
+
+### T1: Create Hello handler with Say method
+- **Scope:** Create `services/api/internal/api/handlers/hello.go` with:
+  - `HelloResponse` struct with `Message string` field
+  - `Hello` struct (handler)
+  - `NewHello(logger *logging.Logger) *Hello` constructor
+  - `Say(w http.ResponseWriter, r *http.Request) error` method that returns greeting
+- **Files:**
+  - Create: `services/api/internal/api/handlers/hello.go`
+- **Depends on:** None
+- **Acceptance criteria:**
+  - [ ] `HelloResponse` struct defined with `json:"message"` tag
+  - [ ] `Hello` handler struct created with logger field
+  - [ ] `NewHello` constructor follows existing pattern from `example.go`
+  - [ ] `Say` method uses `httpresponse.OK()` to return `HelloResponse{Message: "Hello, World!"}`
+  - [ ] `Say` method returns `nil` (no error case)
+  - [ ] File compiles without errors
+
+### T2: Add unit tests for Hello handler
+- **Scope:** Create `services/api/internal/api/handlers/hello_test.go` with test for `Say` method
+- **Files:**
+  - Create: `services/api/internal/api/handlers/hello_test.go`
+- **Depends on:** T1
+- **Acceptance criteria:**
+  - [ ] Test file follows pattern from `example_test.go`
+  - [ ] `TestHello_Say` test verifies HTTP 200 status
+  - [ ] Test verifies response contains `data` field
+  - [ ] Test verifies `data.message` equals `"Hello, World!"`
+  - [ ] All tests pass
+
+### T3: Register /hello route in routes.go
+- **Scope:** Update `services/api/internal/api/routes.go` to:
+  - Initialize `helloHandler` using `handlers.NewHello(logger)`
+  - Register `GET /api/v1/hello` route with `app.Wrap(helloHandler.Say)`
+- **Files:**
+  - Modify: `services/api/internal/api/routes.go`
+- **Depends on:** T1
+- **Acceptance criteria:**
+  - [ ] `helloHandler` initialized alongside other handlers
+  - [ ] Route registered in public routes section (before auth group)
+  - [ ] Route uses `app.Wrap()` pattern
+  - [ ] Route path is `/hello` (under `/api/v1` group)
+
+### T4: Add OpenAPI documentation for /hello endpoint
+- **Scope:** Update `services/api/internal/api/spec.go` to:
+  - Add "Hello" tag with description "Simple greeting endpoint"
+  - Define `HelloResponse` schema
+  - Add `/api/v1/hello` GET path with response documentation
+- **Files:**
+  - Modify: `services/api/internal/api/spec.go`
+- **Depends on:** T3
+- **Acceptance criteria:**
+  - [ ] "Hello" tag added with appropriate description
+  - [ ] `HelloResponse` schema defined with `message` field
+  - [ ] GET `/api/v1/hello` path documented
+  - [ ] Response shows 200 with `{data, meta}` envelope containing `HelloResponse`
+  - [ ] No security requirement (public endpoint)
+  - [ ] OpenAPI spec renders correctly at `/docs`
+
+### T5: Verify integration and run quality checks
+- **Scope:** Run the service and verify end-to-end functionality:
+  - Build passes
+  - Tests pass
+  - Endpoint responds correctly
+  - OpenAPI docs show the new endpoint
+- **Files:** None (verification only)
+- **Depends on:** T1, T2, T3, T4
+- **Acceptance criteria:**
+  - [ ] `go build ./...` succeeds for services/api
+  - [ ] `go test ./...` passes for services/api
+  - [ ] `GET /api/v1/hello` returns 200 with `{"data": {"message": "Hello, World!"}, "meta": {...}}`
+  - [ ] `/docs` shows Hello endpoint under "Hello" tag
+  - [ ] Response includes `request_id` in meta (via middleware)
