+# SmartRequest API Update - January 2025
+
+## Context
+The @push.rocks/smartrequest package (v4.2.1) uses a new chainable API that replaced the old function-based API.
+
+## Changes Made
+
+### Old API (v2.x)
+```typescript
+const response = await plugins.smartrequest.request(url, {
+  headers: this.headers,
+  method: 'GET',
+  queryParams: { key: value }
+});
+const data = response.body;
+```
+
+### New API (v4.x)
+```typescript
+const requestBuilder = plugins.smartrequest.SmartRequest.create()
+  .url(url)
+  .headers(this.headers)
+  .query({ key: value });
+
+const response = await requestBuilder.get();
+const data = await response.json();
+```
+
+## Key Differences
+1. **Request Creation**: Use `SmartRequest.create()` instead of direct function call
+2. **Chainable Methods**: Configure requests with `.url()`, `.headers()`, `.query()`
+3. **HTTP Methods**: Use `.get()`, `.post()`, `.delete()` etc. instead of method parameter
+4. **Response Parsing**: Call `.json()` on response to get parsed data (was `.body` before)
+
+## Files Updated
+- `ts/classes.giteaassets.ts` - Updated the `getFiles()` method to use new API
+
+## Testing
+All tests pass successfully, including the GiteaAssets tests that fetch real data from code.foss.global.
