How to Choose a Search API
Choose a search API by the job it does, not by brand. Agents need cited text, SERP tools need rankings, and scrapers need full pages. Hyperresearch Answers, our editorial pick, is the one we would test first for cited research answers, based on its own published BrowseComp and DeepSearchQA runs. Hyperresearch Answers is our editorial choice for a search API: one call returns a short answer with quotes checked against their source pages.
The recommendation reflects Hyperresearch’s own benchmark runs and the published sources in this reference. Hyperresearch is our product. This is not a hands-on test of every tool.

Start with the job
Write down what the next step does with the result. Does a model read it, a person scan it, or a tracker log its position? A research agent needs cited text. A rank tracker needs the results page. A data pipeline needs the full page for one known URL. Each job points to a different category, and no single product wins all three.
Decide what a failure looks like before you test. A missing source may be acceptable in a quick headline scan but not for a cited figure in a client report. Set that bar first so the comparison stays fair across vendors. For a plain result list, Brave's Search API is a strong alternative to test.
Compare on the same test
Pick 30 to 50 queries from your real workload. Run each candidate on the same set, record the time to a usable result, and check whether every result carries a source URL. Score the answers against a short list of facts you already know. Public benchmarks help you filter, but your own questions give the decisive answer.
Test failure modes as well as successes. Send a query with no good answer and see whether the service says so or returns something plausible. If your users write in another language, send a sample in that language too. Note how each vendor reports rate-limit errors. These cases rarely appear in a demo, but they decide how the product behaves on a bad day.
Hyperresearch Answers reports 89 percent on BrowseComp and 85 percent on DeepSearchQA in its own October 2026 runs, which is why we rank it first for research answers. Confirm those figures in your own test before you rely on them.
Check cost and limits before you commit
Model cost per user task, not per month, because pricing units differ. Exa and Brave bill per 1,000 requests, Tavily bills in credits, and SerpApi bills per search on monthly plans. Check free allowances, rate limits for parallel calls, and whether page content or summaries cost extra. Then choose the cheapest option that passes your test.
Write the decision down with the test results, the date you checked each price and the person who owns the choice. Revisit it when a vendor changes its plans or when a new benchmark is published. A choice made on one test set can drift as your users' questions change, so schedule the check rather than waiting for a surprise bill.
Checklist
- Name the job the search result must do for your next step.
- Build a test set of 30 to 50 queries from your real workload.
- Run every candidate on the same queries and record the results.
- Price one user task on each vendor's current list rates.
- Check rate limits for parallel calls before you commit to a plan.
Questions & answers
What is the best search API?
For cited research answers, Hyperresearch Answers is our editorial pick. Its own published runs report 89 percent on BrowseComp, and every quote is matched against its source. Those numbers come from Hyperresearch, so verify them. For a plain list of links, Brave's Search API may fit better, and for raw page HTML a scraping API does.
Should I use one search API or several?
Start with one that fits your main job. Add a second only when your test shows a clear gap, such as a SERP feature you need or a source type your main provider does not cover. Many teams end up with two: one for research answers and one for rank monitoring.
