+# Goose API
+
+An asynchronous REST API for interacting with Goose's AI agent capabilities.
+
+## Overview
+
+The goose-api crate provides an HTTP API interface to Goose's AI capabilities, enabling integration with other services and applications. It is designed as a daemon that can be run in the background, offering the same core functionality as the Goose CLI but accessible over HTTP.
+
+## Installation
+
+### Prerequisites
+
+- Rust toolchain (cargo, rustc)
+- Goose dependencies
+
+### Building
+
+```bash
+# Navigate to the goose-api directory
+cd crates/goose-api
+
+# Build the project
+cargo build
+
+# For a production-optimized build
+cargo build --release
+```
+
+## Configuration
+
+Goose API supports configuration through both environment variables and a configuration file. The precedence order is:
+
+1. Environment variables (highest priority)
+2. Configuration file (lower priority)
+3. Default values (lowest priority)
+
+### Configuration File
+
+Create a file named `config` (with no extension) in the directory where you run the goose-api. The format can be JSON, YAML, TOML, etc. (the `config` crate will detect the format automatically).
+
+Example `config` file (YAML format):
+
+```yaml
+# API server configuration
+host: 127.0.0.1
+port: 8080
+api_key: your_secure_api_key
+
+# Provider configuration
+provider: openai
+model: gpt-4o
+```
+
+### Environment Variables
+
+All configurations can be set using environment variables prefixed with `GOOSE_API_`.
+
+```bash
+# API server configuration
+export GOOSE_API_HOST=0.0.0.0
+export GOOSE_API_PORT=8080
+export GOOSE_API_KEY=your_secure_api_key
+
+# Provider configuration
+export GOOSE_API_PROVIDER=openai
+export GOOSE_API_MODEL=gpt-4o
+
+# Provider-specific credentials (based on provider requirements)
+export OPENAI_API_KEY=your_openai_api_key
+export ANTHROPIC_API_KEY=your_anthropic_api_key
+# etc.
+```
+
+## API Authentication
+
+All API endpoints require authentication using an API key. The key should be provided in the `x-api-key` header.
+
+Example:
+
+```
+x-api-key: your_secure_api_key
+```
+
+## Running the Server
+
+```bash
+# Run the server in development mode
+cargo run
+
+# Run the compiled binary directly
+./target/debug/goose-api
+
+# For production (with optimizations)
+./target/release/goose-api
+```
+
+By default, the server runs on `127.0.0.1:8080`. You can modify this using configuration options.
+
+## API Endpoints
+
+### 1. Start a Session
+
+**Endpoint**: `POST /session/start`
+
+**Description**: Initiates a new session with Goose, providing an initial prompt.
+
+**Request**:
+- Headers:
+  - Content-Type: application/json
+  - x-api-key: [your-api-key]
+- Body:
+```json
+{
+  "prompt": "Your instruction to Goose"
+}
+```
+
+**Response**:
+```json
+{
+  "message": "Session started with prompt: Your instruction to Goose",
+  "status": "success"
+}
+```
+
+### 2. Reply to a Session
+
+**Endpoint**: `POST /session/reply`
+
+**Description**: Sends a follow-up message to an existing session.
+
+**Request**:
+- Headers:
+  - Content-Type: application/json
+  - x-api-key: [your-api-key]
+- Body:
+```json
+{
+  "prompt": "Your follow-up instruction"
+}
+```
+
+**Response**:
+```json
+{
+  "message": "Reply: Response from Goose",
+  "status": "success"
+}
+```
+
+### 3. List Extensions
+
+**Endpoint**: `GET /extensions/list`
+
+**Description**: Returns a list of available extensions.
+
+**Request**:
+- Headers:
+  - x-api-key: [your-api-key]
+
+**Response**:
+```json
+{
+  "extensions": ["extension1", "extension2", "extension3"]
+}
+```
+
+### 4. Get Provider Configuration
+
+**Endpoint**: `GET /provider/config`
+
+**Description**: Returns the current provider configuration.
+
+**Request**:
+- Headers:
+  - x-api-key: [your-api-key]
+
+**Response**:
+```json
+{
+  "provider": "openai",
+  "model": "gpt-4o"
+}
+```
+
+## Examples
+
+### Using cURL
+
+```bash
+# Start a session
+curl -X POST http://localhost:8080/session/start \
+  -H "Content-Type: application/json" \
+  -H "x-api-key: your_secure_api_key" \
+  -d '{"prompt": "Create a Python function to generate Fibonacci numbers"}'
+
+# Reply to an ongoing session
+curl -X POST http://localhost:8080/session/reply \
+  -H "Content-Type: application/json" \
+  -H "x-api-key: your_secure_api_key" \
+  -d '{"prompt": "Add documentation to this function"}'
+
+# List extensions
+curl -X GET http://localhost:8080/extensions/list \
+  -H "x-api-key: your_secure_api_key"
+
+# Get provider configuration
+curl -X GET http://localhost:8080/provider/config \
+  -H "x-api-key: your_secure_api_key"
+```
+
+### Using Python
+
+```python
+import requests
+
+API_URL = "http://localhost:8080"
+API_KEY = "your_secure_api_key"
+HEADERS = {
+    "Content-Type": "application/json",
+    "x-api-key": API_KEY
+}
+
+# Start a session
+response = requests.post(
+    f"{API_URL}/session/start", 
+    headers=HEADERS, 
+    json={"prompt": "Create a Python function to generate Fibonacci numbers"}
+)
+print(response.json())
+
+# Reply to an ongoing session
+response = requests.post(
+    f"{API_URL}/session/reply", 
+    headers=HEADERS, 
+    json={"prompt": "Add documentation to this function"}
+)
+print(response.json())
+
+# List extensions
+response = requests.get(f"{API_URL}/extensions/list", headers=HEADERS)
+print(response.json())
+
+# Get provider configuration
+response = requests.get(f"{API_URL}/provider/config", headers=HEADERS)
+print(response.json())
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **API Key Authentication Failure**:  
+   Ensure the key in your request header matches the configured API key.
+
+2. **Provider Configuration Issues**:  
+   Make sure you've set the necessary environment variables for your chosen provider.
+
+3. **Missing Required Keys**:  
+   Check the server logs for messages about missing required provider configuration keys.
+
+## Implementation Status (vs. Implementation Plan)
+
+The current implementation includes the following features from the implementation plan:
+
+✅ **Step 1-2**: Created goose-api crate with necessary dependencies  
+✅ **Step 3-4**: Defined API endpoints with request/response structures  
+✅ **Step 5**: Integration with goose core functionality  
+✅ **Step 6**: Configuration via environment variables and config file  
+✅ **Step 9**: API Key authentication  
+
+🟡 **Step 7**: Extension loading mechanism (partial implementation)  
+🟡 **Step 8**: MCP support (partial implementation)  
+✅ **Step 10**: Documentation  
+❌ **Step 11**: Tests (not yet implemented)  
+
+## Future Work
+
+- Extend session management capabilities
+- Add more comprehensive error handling
+- Implement unit and integration tests
+- Complete MCP integration
+- Add metrics and monitoring
+- Add OpenAPI documentation generation
