+# CHORUS API Overview
+
+## Introduction
+
+The CHORUS API provides HTTP REST endpoints for interacting with the CHORUS autonomous agent system. The API exposes functionality for accessing distributed logs, system health monitoring, and setup/configuration management.
+
+## Architecture
+
+The API layer consists of two primary components:
+
+1. **HTTPServer** (`api/http_server.go`) - Core REST API server providing runtime access to system data
+2. **SetupManager** (`api/setup_manager.go`) - Configuration and initial setup API for system initialization
+
+## Base Configuration
+
+- **Default Port**: Configurable (typically 8080)
+- **Protocol**: HTTP/1.1
+- **Content-Type**: `application/json`
+- **CORS**: Enabled for all origins (suitable for development; restrict in production)
+
+## Authentication
+
+**Current Status**: No authentication required
+
+The API currently operates without authentication. For production deployments, consider implementing:
+- Bearer token authentication
+- API key validation
+- OAuth2/OIDC integration
+- mTLS for service-to-service communication
+
+## Core Components
+
+### HTTPServer
+
+The main API server handling runtime operations:
+
+- **Hypercore Log Access** - Query distributed log entries with flexible filtering
+- **Health Monitoring** - System health and status checks
+- **Statistics** - Log and system statistics
+
+### SetupManager
+
+Handles initial system configuration and discovery:
+
+- **System Detection** - Hardware, network, and software environment discovery
+- **Repository Configuration** - Git provider setup and validation
+- **Network Discovery** - Automatic detection of cluster machines
+- **SSH Testing** - Remote system access validation
+
+## API Endpoints
+
+See [HTTP Server Documentation](./http-server.md) for complete endpoint reference.
+
+### Quick Reference
+
+| Endpoint | Method | Purpose |
+|----------|--------|---------|
+| `/api/health` | GET | Health check |
+| `/api/status` | GET | Detailed system status |
+| `/api/hypercore/logs` | GET | Query log entries |
+| `/api/hypercore/logs/recent` | GET | Recent log entries |
+| `/api/hypercore/logs/since/{index}` | GET | Logs since index |
+| `/api/hypercore/logs/stats` | GET | Log statistics |
+
+## Integration Points
+
+### Hypercore Log Integration
+
+The API directly integrates with CHORUS's distributed Hypercore-inspired log system:
+
+```go
+type HypercoreLog interface {
+    Length() uint64
+    GetRange(start, end uint64) ([]LogEntry, error)
+    GetRecentEntries(limit int) ([]LogEntry, error)
+    GetEntriesSince(index uint64) ([]LogEntry, error)
+    GetStats() map[string]interface{}
+}
+```
+
+**Log Entry Types**:
+- Task coordination (announced, claimed, progress, completed, failed)
+- Meta-discussion (plan proposed, objection raised, consensus reached)
+- System events (peer joined/left, capability broadcast, network events)
+
+### PubSub Integration
+
+The HTTPServer includes PubSub integration for real-time event broadcasting:
+
+```go
+type PubSub interface {
+    Publish(topic string, message interface{}) error
+    Subscribe(topic string) (chan interface{}, error)
+}
+```
+
+**Topics**:
+- Task updates
+- System events
+- Peer connectivity changes
+- Log replication events
+
+## Response Formats
+
+### Standard Success Response
+
+```json
+{
+  "entries": [...],
+  "count": 50,
+  "timestamp": 1727712345,
+  "total": 1024
+}
+```
+
+### Standard Error Response
+
+HTTP error status codes with plain text error messages:
+
+```
+HTTP/1.1 400 Bad Request
+Invalid start parameter
+```
+
+```
+HTTP/1.1 500 Internal Server Error
+Failed to get log entries: database connection failed
+```
+
+## CORS Configuration
+
+The API implements permissive CORS for development:
+
+```
+Access-Control-Allow-Origin: *
+Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS
+Access-Control-Allow-Headers: Content-Type, Authorization
+```
+
+**Production Recommendation**: Restrict `Access-Control-Allow-Origin` to specific trusted domains.
+
+## Timeouts
+
+- **Read Timeout**: 15 seconds
+- **Write Timeout**: 15 seconds
+- **Idle Timeout**: 60 seconds
+
+## Error Handling
+
+The API uses standard HTTP status codes:
+
+- `200 OK` - Successful request
+- `400 Bad Request` - Invalid parameters or malformed request
+- `404 Not Found` - Resource not found
+- `500 Internal Server Error` - Server-side error
+
+Error responses include descriptive error messages in the response body.
+
+## Usage Examples
+
+### Health Check
+
+```bash
+curl http://localhost:8080/api/health
+```
+
+### Query Recent Logs
+
+```bash
+curl http://localhost:8080/api/hypercore/logs/recent?limit=10
+```
+
+### Get Log Statistics
+
+```bash
+curl http://localhost:8080/api/hypercore/logs/stats
+```
+
+## Performance Considerations
+
+- **Pagination**: Use `limit` parameters to avoid large result sets
+- **Caching**: Consider implementing response caching for frequently accessed data
+- **Rate Limiting**: Not currently implemented; add for production use
+- **Connection Pooling**: Server handles concurrent connections efficiently
+
+## Future Enhancements
+
+1. **WebSocket Support** - Real-time log streaming and event notifications
+2. **Authentication** - Bearer token or API key authentication
+3. **Rate Limiting** - Per-client rate limiting and quota management
+4. **GraphQL Endpoint** - Flexible query interface for complex data requirements
+5. **Metrics Export** - Prometheus-compatible metrics endpoint
+6. **API Versioning** - Version prefix in URL path (e.g., `/api/v1/`, `/api/v2/`)
