We tested 5 tools for accuracy and speed. This is the best web search API in 2026
Blog post from Parallel Web Systems
The evaluation of five web search APIs on the BrowseComp benchmark highlights the importance of considering both latency and accuracy together when selecting an API for AI agents. The benchmark, conducted by OpenAI using 1,266 complex, multi-hop questions, showed that Parallel's API achieved the fastest latency of 216 ms with the highest accuracy of 51%, making it suitable for high-accuracy, low-latency research. Exa, Brave Search, SerpAPI, and Tavily all presented various trade-offs between speed and accuracy, with Brave Search offering the best non-Parallel accuracy at 38.3% despite slower latency. The study emphasizes running personalized tests on real production queries to make an informed decision, as published figures serve only as a baseline. It also suggests regular re-evaluation to account for updates and changes in provider offerings and query dynamics, ensuring the chosen API remains effective for specific needs.
