Agent context: **Provider Choice** I’d choose **Tavily Search API** as the managed web-search/retrieval provider. Repo fit is the main reason: this app has a clean provider-neutral LLM layer in [llm_client.py](/home/user/worktrees/attempt-0b9b2614-9338-4b7b-9f4b-1dcb3e0e67b5-cap-0/llm_client.py:50), and `TravelPlanner.generate_itinerary` currently just builds a prompt and sends it to the selected model in [travel_planner.py](/home/user/worktrees/attempt-0b9b2614-9338-4b7b-9f4b-1dcb3e0e67b5-cap-0/travel_planner.py:61). Tavily can be added as an independent retrieval step before the LLM call, without tying grounding to Google, OpenAI, Anthropic, or OpenRouter. Tavily is also strong on the exact freshness requirement: its Search API supports `news` for real-time updates and also exposes `finance` as a search topic, plus `time_range` and cleaned raw page content for retrieval-grounded prompts. The docs describe `news` as useful for real-time updates, list `general`, `news`, and `finance` topics, and support `include_raw_content` for cleaned parsed HTML content. Sources: Tavily Search docs lines 278-292 and 349, plus pricing docs showing basic search at 1 credit and advanced search at 2 credits. **Main Alternatives Considered** - **Exa**: Strong runner-up. It has search plus content extraction, published/crawl date filters, and explicit live-crawl controls. Its docs say `livecrawl: "always"` is best for real-time data like news, stock prices, and live events, and `preferred` is a good production default. I’d choose Exa if page freshness on known URLs mattered more than simple agent search integration. - **Brave Search API**: Good independent index, news endpoint, freshness filtering, and LLM context endpoint. It is attractive for cost and scale, but it is more search-result/context oriented than full retrieval orchestration for this repo. - **Perplexity Sonar**: Good if you want a combined answer engine with citations, but it would partly replace this repo’s LLM abstraction rather than feed retrieved evidence into the existing Google/OpenAI/Anthropic/OpenRouter flow. - **SerpAPI**: Best for specialized travel verticals like real-time flights, hotels, prices, and availability, but it is more a SERP/vertical-data API than a general retrieval layer. It would be useful later as a specialized supplement, not the first general grounding provider. - **Google Gemini Grounding / OpenAI Web Search / Anthropic Web Search**: Strong built-in options, but each binds grounding to one model provider. That conflicts with this repo’s multi-provider design in [config.py](/home/user/worktrees/attempt-0b9b2614-9338-4b7b-9f4b-1dcb3e0e67b5-cap-0/config.py:19). Gemini’s Google Search grounding is very compelling for freshness, and OpenAI’s web search includes citations, but both would make search behavior provider-specific. - **Google Custom Search JSON API**: Not a good choice now. Google’s docs say it is not available for new customers and existing customers must transition by January 1, 2027. **Docs Actually Consulted** Tavily Search API and credits/pricing; Exa Search, live-crawling, and pricing; Brave Search API and News Search docs; Perplexity Sonar docs; SerpAPI web/travel use-case docs; Google Gemini Grounding with Google Search; OpenAI Web Search; Google Custom Search JSON API. **Recommended Integration Shape** Add a small `web_retriever.py` around Tavily, configure `TAVILY_API_KEY`, retrieve 5-10 recent sources with `topic=news` or `topic=finance` when the query is time-sensitive, include cleaned source snippets/content in the itinerary prompt, and require the LLM to cite source URLs for prices, opening hours, availability, and recent events. **Provider Choice** I’d choose **Tavily Search API** as the managed web-search/retrieval provider. Repo fit is the main reason: this app has a clean provider-neutral LLM layer in [llm_client.py](/home/user/worktrees/attempt-0b9b2614-9338-4b7b-9f4b-1dcb3e0e67b5-cap-0/llm_client.py:50), and `TravelPlanner.generate_itinerary` currently just builds a prompt and sends it to the selected model in [travel_planner.py](/home/user/worktrees/attempt-0b9b2614-9338-4b7b-9f4b-1dcb3e0e67b5-cap-0/travel_planner.py:61).
