+# API Headers Testing Scripts
+
+This directory contains scripts for testing the security headers and API compatibility of the Ploughshares application.
+
+## Scripts Overview
+
+1. **test_headers.sh** - Tests general HTTP headers for both UI and API endpoints
+2. **test_api_curl.sh** - Tests API endpoints with various curl commands and parameters
+3. **test_api_headers.sh** - Specifically analyzes security headers for API compatibility
+
+## Usage
+
+All scripts accept an optional URL parameter. If not provided, they default to `http://localhost:5005`.
+
+```bash
+# Test against local development environment
+./test_headers.sh
+
+# Test against production
+./test_headers.sh https://ploughshares.nixc.us
+```
+
+## Security Headers Analysis
+
+The scripts check for the following important headers:
+
+### Content Security Policy (CSP)
+- Ensures `unsafe-inline` and `unsafe-eval` are present for API compatibility
+- Verifies `connect-src` includes wildcard (*) for API access
+- Checks critical protections like `object-src: 'none'` and `frame-ancestors: 'none'`
+
+### CORS Headers
+- `Access-Control-Allow-Origin`
+- `Access-Control-Allow-Methods`
+- `Access-Control-Allow-Headers`
+
+### Resource Policies
+- `Cross-Origin-Resource-Policy` should be `cross-origin` for API endpoints
+- `Cross-Origin-Resource-Policy` should be `same-origin` for UI endpoints
+
+## Troubleshooting
+
+If API requests are failing, check the following:
+
+1. **CSP Issues**: The Content-Security-Policy header must include:
+   - `'unsafe-inline'` and `'unsafe-eval'` in script-src
+   - `*` in connect-src
+   - `data:` and `blob:` in appropriate directives
+
+2. **CORS Issues**: API endpoints must have:
+   - `Access-Control-Allow-Origin: *` (or specific origins)
+   - `Access-Control-Allow-Methods` with appropriate HTTP methods
+   - `Access-Control-Allow-Headers` with at least `Content-Type` and `Authorization`
+
+3. **Resource Policy Issues**: API endpoints should have:
+   - `Cross-Origin-Resource-Policy: cross-origin`
+
+## Current Configuration
+
+The current configuration uses a permissive CSP that works for both UI and API routes:
+
+```python
+csp = {
+    'default-src': ["'self'", "'unsafe-inline'", "'unsafe-eval'", "data:", "blob:"],
+    'script-src': ["'self'", "'unsafe-inline'", "'unsafe-eval'"] + ([f"'sha256-{CSP_JS_HASH}'"] if CSP_JS_HASH else []),
+    'style-src': ["'self'", "'unsafe-inline'"] + 
+                ([f"'sha256-{CSP_CSS_HASH}'"] if CSP_CSS_HASH else []) + 
+                ([f"'sha256-{CSP_CUSTOM_CSS_HASH}'"] if CSP_CUSTOM_CSS_HASH else []),
+    'img-src': ["'self'", "data:", "blob:"],
+    'font-src': ["'self'", "data:"],
+    'connect-src': ["'self'", "*"],
+    'manifest-src': "'self'",
+    'object-src': "'none'",  # Still explicitly disallow objects
+    'frame-ancestors': "'none'",  # Still prevent framing
+    'base-uri': "'self'",
+    'form-action': "'self'"
+}
+```
+
+CORS headers are added for API routes in an after_request handler:
+
+```python
+@app.after_request
+def add_api_headers(response):
+    if request.path.startswith('/api/'):
+        # Add CORS headers for API routes
+        response.headers['Access-Control-Allow-Origin'] = '*'
+        response.headers['Access-Control-Allow-Methods'] = 'GET, POST, PUT, DELETE, OPTIONS'
+        response.headers['Access-Control-Allow-Headers'] = 'Content-Type, Authorization'
+        response.headers['Cross-Origin-Resource-Policy'] = 'cross-origin'
+    else:
+        # For UI routes, add additional security headers
+        for header, value in additional_headers.items():
+            response.headers[header] = value
+    
+    return response
+```
