An agent tool connects a question to sources the model can use. Start with whether those sources let the agent finish the job, then compare the time and cost of each search call. In this benchmark, every provider gets the same agent and developer questions. Accuracy means task completion: the resulting patch must pass its checks and cite a source returned during the run. ### Search results, scraped pages and generated answers Choose the output contract before choosing a vendor. Ranked links and excerpts fit an agent that reasons over sources itself. Scraped page text adds context when a result excerpt is insufficient. A generated answer adds a separate model and its own scoring problem. The table here compares agents using search results; the linked search-plus-scrape board measures the expanded workflow separately. ### Connect the tool and keep its evidence Use the official endpoint and configuration in the table. Return source URLs alongside text, retain those URLs through the agent loop, and record the number of searches and tokens used to complete each task. Compare providers on the same questions, result limit and model. Check citation support and completion quality before choosing the fastest row. ### Turn per-query pricing into an agent budget A task can make several searches. Search spend equals search calls multiplied by the per-call rate; add model tokens and any scrape charges to estimate the full task bill. The table keeps the recorded price per 1,000 queries separate from measured median task cost. Free-tier limits and paid-plan conditions appear beside the price. ## Benchmark method and source data Task completion on 100 developer questions with the same agent using search results. Each task requires a passing patch and a citation from the run's sources. Search latency and total task latency are shown separately. Each row is one measured configuration. Missing measurements appear as a dash.

Best web search API by accuracy (task completion) in this benchmark: Perplexity at 77.3%. Fastest search: Parallel turbo, 333ms (64.7% task completion). Lowest recorded search price: TinyFish, $0.00 per 1,000 queries within its free-tier limits. ### Which benchmark does the main ranking use? Task completion on 100 developer questions with the same agent using search results. Each task requires a passing patch and a citation from the run's sources. Search latency and total task latency are shown separately. ### What does the price per 1,000 queries include? The recorded search endpoint's request price. Model-token spend, optional scraping and plan conditions are separate. For rows with task measurements, median task cost is shown in its own column. Check the linked provider terms for current pricing. ## Related search API comparisons [Web search APIs for AI & LLM developers →](https://openbenchmarks.com/web-search/best-web-search-api-for-ai-llm-developers) [Web search APIs & MCPs for AI agents and developers →](https://openbenchmarks.com/web-search/best-web-search-apis-and-mcps-for-ai-agents) [Search providers for LLM applications →](https://openbenchmarks.com/web-search/best-search-providers-for-llm-applications) [AI search engines for agents →](https://openbenchmarks.com/web-search/best-ai-search-engines-for-agents) [Free web search APIs for AI agents →](https://openbenchmarks.com/web-search/best-free-web-search-api-for-ai-agents) [Web search APIs for RAG →](https://openbenchmarks.com/web-search/best-web-search-api-for-rag) [Independent web search API comparison →](https://openbenchmarks.com/web-search/best-web-search-api-comparison) [Best fast web search API →](https://openbenchmarks.com/web-search/best-fast-web-search-api) [Best search and scrape API →](https://openbenchmarks.com/web-search/best-search-and-scrape-api) [Best scrape API for AI agents →](https://openbenchmarks.com/web-search/best-scrape-api-for-ai-agents) [Best search API for deep research agents →](https://openbenchmarks.com/web-search/best-search-api-for-deep-research-agents) [Best search API for company research →](https://openbenchmarks.com/web-search/best-search-api-for-company-research) [Best search API for sales agents →](https://openbenchmarks.com/web-search/best-search-api-for-sales-agents) [Best search API for coding documentation →](https://openbenchmarks.com/web-search/best-search-api-for-coding-documentation) [Best web search API for grounding →](https://openbenchmarks.com/web-search/best-web-search-api-for-grounding) [Best search API for news →](https://openbenchmarks.com/web-search/best-search-api-for-news) [Best web search APIs for AI →](https://openbenchmarks.com/web-search/best-web-search-api-for-ai) [LLM apps comparison →](https://openbenchmarks.com/web-search/best-web-search-api-for-llm-apps) [Pricing per 1,000 queries →](https://openbenchmarks.com/web-search/cheapest-search-api) [← Web Search Benchmark](https://openbenchmarks.com/web-search)
