These endpoints allow Claude Code (or any automation tool) to: + +1. Take screenshots of the current UI state +2. Navigate to specific menu locations +3. Execute key sequences +4. Get the menu structure + +## API Endpoints + +### 1. Consolidated Screenshot API + +**Endpoint:** `GET /api/screenshot` or `POST /api/screenshot` + +The single endpoint for all screenshot and navigation needs - always returns a screenshot at native resolution. + +#### GET Request (Simple) +**Parameters:** +- `path` (optional): Menu path like "settings/display" +- `format` (optional): "png" or "jpeg" (default: jpeg) + +**Examples:** +```bash +# Basic screenshot +curl "http://pifinder.local/api/screenshot" + +# Navigate to menu path then screenshot +curl "http://pifinder.local/api/screenshot?path=settings/display" + +# PNG format +curl "http://pifinder.local/api/screenshot?format=png" +``` + +#### POST Request (Advanced) +**Content-Type:** `application/json` + +**Body:** +```json +{ + "path": "settings/display", // optional menu path + "keys": ["UP", "DOWN", "A"], // optional key sequence + "format": "jpeg" // optional format +} +``` + +**Available Keys:** +- Direction: `"UP"`, `"DN"`, `"A"`, `"B"`, `"C"`, `"D"` +- Special: `"SQUARE"`, `"ALT_PLUS"`, `"ALT_MINUS"`, `"ALT_LEFT"`, etc. +- Numbers: `0-9` (as integers) + +**Examples:** +```bash +# Navigate to path then execute keys +curl -X POST "http://pifinder.local/api/screenshot" \ + -H "Content-Type: application/json" \ + -d '{"path": "settings", "keys": ["DOWN", "DOWN", "A"]}' + +# Execute key sequence only +curl -X POST "http://pifinder.local/api/screenshot" \ + -H "Content-Type: application/json" \ + -d '{"keys": ["SQUARE", "UP", "A"]}' +``` + +### 2. Menu Structure API + +**Endpoint:** `GET /api/menu-structure` + +Returns the complete menu structure as JSON, including current UI stack state. + +**Example:** +```bash +curl "http://pifinder.local/api/menu-structure" +``` + +## Authentication + +All API endpoints require authentication using the same cookie-based system as the web interface. You'll need to: + +1. First login at `/login` with the PiFinder password +2. Use the session cookie for subsequent API calls + +## Usage Workflow for Claude Code + +### Typical Automation Flow: + +1. **Make code changes** to PiFinder UI components +2. **Start the PiFinder app** +3. **Take initial screenshot:** + ```bash + curl "http://pifinder.local/api/screenshot" > current_ui.jpg + ``` +4. **Navigate to specific screen:** + ```bash + curl -X POST "http://pifinder.local/api/screenshot" \ + -H "Content-Type: application/json" \ + -d '{"path": "settings/display"}' > settings_screen.jpg + ``` +5. **Test specific interactions:** + ```bash + curl -X POST "http://pifinder.local/api/screenshot" \ + -H "Content-Type: application/json" \ + -d '{"keys": ["DOWN", "A", "SQUARE"]}' > interaction_result.jpg + ``` +6. **Iterate based on visual feedback** + +### Advanced Usage: + +**Get menu structure first:** +```bash +curl "http://pifinder.local/api/menu-structure" | jq . +``` + +**Complex navigation and testing:** +```bash +curl -X POST "http://pifinder.local/api/screenshot" \ + -H "Content-Type: application/json" \ + -d '{"path": "objects", "keys": ["DOWN", "DOWN", "A", "1", "2", "3"]}' > test_result.jpg +``` + +## Key Advantages + +- **Single Endpoint**: One `/api/screenshot` handles all use cases +- **Always Returns Image**: Every operation ends with visual feedback +- **Native Resolution**: No scaling - returns actual display resolution +- **Flexible Navigation**: Supports both path-based and key-sequence navigation +- **Format Options**: PNG for exact pixels, JPEG for smaller files + +## Integration with Playwright MCP + +This API works perfectly with Claude Code's Playwright MCP for visual UI testing: + +```javascript +// Take screenshot and analyze with Claude Code +const response = await fetch('http://pifinder.local/api/screenshot', { + method: 'POST', + headers: {'Content-Type': 'application/json'}, + body: JSON.stringify({"path": "radec_entry", "keys": ["SQUARE"]}) +}); +const imageBuffer = await response.buffer(); +// Use mcp__playwright tools to analyze the image +``` + +This consolidated approach eliminates API redundancy while providing all the functionality needed for comprehensive UI automation and testing workflows. \ No newline at end of file diff --git a/python/PiFinder/server.py b/python/PiFinder/server.py index 6f1bea592..059f8d65a 100644 --- a/python/PiFinder/server.py +++ b/python/PiFinder/server.py @@ -936,6 +936,145 @@ def serve_pil_image(): return img_byte_arr + @app.route("/api/screenshot", method=["GET", "POST"]) + @auth_required + def api_screenshot(): + """ + Consolidated screenshot API with optional navigation + + GET query parameters: + -
