+# ADR 0026: Composite Info Endpoint vs Separate Calls
+
+**Status:** Implemented (2026-05-05 — PR pending)
+
+## Context
+
+The application currently exposes several endpoints that provide system information:
+- `/api/version` - returns version, commit, build date, Go version (cached 60s)
+- `/api/health` - returns `{"status":"healthy"}` (simple liveness)
+- `/api/healthz` - returns rich health info: status, version, uptime_seconds, timestamp
+- `/api/ready` - returns readiness with connection details
+
+Frontend components like `HealthDashboard` currently call `/api/healthz` to display server info. However, there is a need for a **composite endpoint** that aggregates:
+1. Version information (from `/api/version`)
+2. Build metadata (commit hash, build date)
+3. Uptime information (from `/api/healthz`)
+4. Cache status (enabled/disabled)
+5. Health status
+
+This raises an architectural question: **Should we create a new composite `/api/info` endpoint, or should frontend components make multiple separate API calls?**
+
+### The Problem with Separate Calls
+
+If the frontend makes individual calls to `/api/version`, `/api/healthz`, and checks cache config separately:
+
+1. **Multiple network requests**: 3-4 HTTP round trips per page load
+2. **Inconsistent data**: Responses may come from different moments in time
+3. **No caching coordination**: Each endpoint has its own cache key and TTL
+4. **Complex frontend logic**: Need to merge data from multiple sources
+5. **Poor user experience**: Slower page loads, multiple loading states
+
+### Current State Analysis
+
+| Endpoint | Data Provided | Cache TTL | Use Case |
+|----------|---------------|-----------|----------|
+| `/api/version` | version, commit, built, go | 60s | Version info |
+| `/api/healthz` | status, version, uptime_seconds, timestamp | None | K8s probes, health dashboard |
+| `/api/health` | status: "healthy" | None | Simple liveness |
+| `/api/ready` | ready, connections, reason | None | Readiness probes |
+
+The `/api/healthz` endpoint already combines some data (status + version + uptime + timestamp), but it:
+- Doesn't include commit_short
+- Doesn't include build_date separately
+- Doesn't include cache_enabled
+- Is not cached
+- Has Kubernetes-specific field naming (`healthz`)
+
+## Decision Drivers
+
+* **Performance**: Minimize network round trips for frontend
+* **Consistency**: All data should reflect the same point-in-time
+* **Maintainability**: Single source of truth for system info
+* **Caching**: Reuse existing cache infrastructure (ADR-0022)
+* **API Design**: Follow REST principles and existing patterns
+* **Backward Compatibility**: Existing endpoints must remain unchanged
+
+## Considered Options
+
+### Option 1: Composite `/api/info` Endpoint (Chosen)
+
+Create a new endpoint that aggregates all required data in a single call.
+
+**Pros:**
+- ✅ Single network request for frontend
+- ✅ Consistent point-in-time data
+- ✅ Can leverage existing cache infrastructure with key `info:json`
+- ✅ Follows existing pattern of `/api/version` caching
+- ✅ Clean API design - one endpoint, one purpose
+- ✅ Reduces frontend complexity
+- ✅ Better UX - faster page loads
+- ✅ Aligns with ADR-0022 cache strategy (reusable cache key pattern)
+
+**Cons:**
+- ⚠️ Duplicates some data from `/api/healthz` and `/api/version`
+- ⚠️ Requires new endpoint implementation
+- ⚠️ Need to maintain consistency if source endpoints change
+
+### Option 2: Frontend Aggregation with Multiple Calls
+
+Frontend makes separate calls to `/api/version`, `/api/healthz`, and introspects config.
+
+**Pros:**
+- ✅ No backend changes required
+- ✅ Uses existing endpoints
+
+**Cons:**
+- ❌ Multiple network requests (3-4 round trips)
+- ❌ Inconsistent data timing
+- ❌ Complex error handling in frontend
+- ❌ Poor UX - multiple loading states, slower
+- ❌ Each endpoint has different caching behavior
+- ❌ Violates DRY - same data fetched multiple times
+
+### Option 3: Extend `/api/healthz` Endpoint
+
+Add `commit_short`, `build_date`, and `cache_enabled` fields to existing `/api/healthz`.
+
+**Pros:**
+- ✅ Reuses existing endpoint
+- ✅ Single request
+
+**Cons:**
+- ❌ Breaks backward compatibility (response schema change)
+- ❌ `/api/healthz` is Kubernetes-focused (naming convention)
+- ❌ Not cached currently
+- ❌ Mixes health probe concerns with version info
+- ❌ Violates single responsibility
+
+### Option 4: GraphQL / Query Parameters
+
+Allow clients to specify which fields they want via query parameters.
+
+**Pros:**
+- ✅ Flexible - clients get exactly what they need
+- ✅ Single endpoint
+
+**Cons:**
+- ❌ Overkill for this use case
+- ❌ Not consistent with existing REST API design
+- ❌ Complex implementation
+- ❌ Not aligned with project architecture (Chi router, REST style)
+
+## Decision Outcome
+
+**Chosen: Option 1 - Composite `/api/info` Endpoint**
+
+We will implement a new `GET /api/info` endpoint that returns a JSON object with all required fields in a single call. This endpoint will:
+
+1. Aggregate data from existing sources (`version` package, `config`, server uptime)
+2. Be cached using the existing cache service with key `info:json`
+3. Use TTL from `config.cache.default_ttl_seconds` (consistent with ADR-0022)
+4. Return `X-Cache: HIT/MISS` headers for debugging
+5. Follow existing Go handler patterns from `pkg/server/server.go`
+
+### Response Schema
+
+```json
+{
+ "version": "1.4.0",
+ "commit_short": "a3f7b2c1",
+ "build_date": "2026-05-04T08:00:00Z",
+ "uptime_seconds": 1234,
+ "cache_enabled": true,
+ "healthz_status": "healthy"
+}
+```
+
+### Rationale
+
+1. **Performance**: Single HTTP request instead of 3-4 separate calls
+2. **Consistency**: All data reflects the same moment in time
+3. **Caching**: Leverages existing cache infrastructure (ADR-0022) with predictable key pattern
+4. **API Design**: Clean, RESTful endpoint with single responsibility
+5. **Maintainability**: Clear separation of concerns - info aggregation is a distinct use case
+6. **Backward Compatibility**: Existing endpoints remain unchanged
+7. **Frontend Simplicity**: Reduces complexity and improves UX
+
+### Cache Strategy
+
+Following ADR-0022 pattern:
+- Cache key: `info:json` (consistent with `version:format` pattern)
+- TTL: `config.cache.default_ttl_seconds` (default 300 seconds)
+- Cache service: `pkg/cache/cache.go` InMemoryService
+- Headers: `X-Cache: HIT` or `X-Cache: MISS`
+
+This allows the endpoint to be fast even under load, while maintaining data freshness.
+
+## Consequences
+
+### Positive
+
+1. **Improved frontend performance**: Single request instead of multiple
+2. **Better UX**: Faster page loads, simpler loading states
+3. **Consistent data**: All fields reflect the same point-in-time
+4. **Cache efficiency**: Reuses existing cache infrastructure
+5. **Clean separation**: Info endpoint handles aggregation, source endpoints unchanged
+6. **Easy to test**: Single endpoint with predictable response
+
+### Negative
+
+1. **Data duplication**: Some fields appear in multiple endpoints
+2. **Maintenance burden**: If source data changes, endpoint must be updated
+3. **New endpoint**: Increases API surface area (though minimal)
+
+### Mitigation
+
+1. Data duplication is acceptable - it's read-only system info
+2. Source the data from the same packages/functions used by other endpoints
+3. The new endpoint has a clear, focused purpose
