Best search and fetch API for AI agents: search-only vs search + fetch
Ranked on the multi-hop search task of the web search benchmark. Each question combines three or four constraints.
Parallel basic (parallel-basic) leads F1 at 46.5% on this run.
Search-only exposes results and snippets; search + fetch also lets the agent open an exact URL the search returned. Compare a provider's F1 across the two boards below: the difference is what page fetching buys on this task, and it is not the same for every API.

F1, precision, recall, and exact-set accuracy are percentages reported as mean ± sample SD across three independent runs; each run aggregates all 45 questions. SD is measured in percentage points. Median time is the median end-to-end time across all runs for each vendor. Median task cost is the median of LLM $ plus search/fetch API $ per agent run. API list price is the PAYG unit rate of the search (and fetch) endpoint the harness calls.

Common questions
Should a research agent use search only, or search and fetch?
It depends on the API. On this task, Perplexity (perplexity) gains the most from page fetch (+8.7 F1 points), while Parallel basic (parallel-basic) changes by -4.2. Fetch adds latency and model cost on every run, so it pays only where snippets are not enough to verify a constraint.
What does search and fetch mean here?
Search-only exposes provider search results and snippets to the agent but no page-reading tool. Search + fetch also lets the agent open an exact URL returned by the search. Both modes run the same agent, the same questions and the same scoring; only the tool set differs.
