+# 51. Implement API Client for Podcast Sources
+
+meta:
+  id: podcast-tui-app-51
+  feature: podcast-tui-app
+  priority: P1
+  depends_on: [50]
+  tags: [api-client, sources, solidjs]
+
+objective:
+- Create API client for podcast sources
+- Handle RSS feed parsing
+- Handle API source queries
+- Handle custom sources
+- Implement error handling
+
+deliverables:
+- `src/api/client.ts` with API client
+- `src/api/rss-parser.ts` with RSS parsing
+- `src/api/source-handler.ts` with source-specific handlers
+
+steps:
+- Create `src/api/client.ts`:
+  - `fetchFeeds(sourceIds: string[]): Promise<Feed[]>`
+  - `fetchEpisodes(feedUrl: string): Promise<Episode[]>`
+  - `searchPodcasts(query: string): Promise<Podcast[]>`
+  - Handle API calls and errors
+- Create `src/api/rss-parser.ts`:
+  - `parseRSSFeed(xml: string): Podcast`
+  - Parse RSS XML
+  - Extract podcast metadata
+  - Extract episodes
+- Create `src/api/source-handler.ts`:
+  - `handleRSSSource(source: PodcastSource): Promise<Feed[]>`
+  - `handleAPISource(source: PodcastSource, query: string): Promise<Podcast[]>`
+  - `handleCustomSource(source: PodcastSource, query: string): Promise<Podcast[]>`
+  - Source-specific logic
+
+tests:
+- Unit: Test RSS parsing
+- Unit: Test API client
+- Unit: Test source handlers
+- Integration: Test API calls
+
+acceptance_criteria:
+- API client fetches data correctly
+- RSS parsing works
+- Source handlers work for all types
+- Errors handled gracefully
+
+validation:
+- Run application and test API calls
+- Test RSS feed parsing
+- Test API source queries
+- Test error handling
+
+notes:
+- Use `feed-parser` library for RSS parsing
+- Use `axios` for API calls
+- Handle rate limiting
+- Cache API responses
+- Add error handling for failed requests
+- Store API keys securely
