Tavily alternatives: 7 web search APIs for AI agents
A neutral look at Tavily alternatives for AI agents, covering Exa, Parallel, Keenable, Brave, Serper, You.com and Sonar, plus when to stay on Tavily.
The main Tavily alternatives for agent builders are Exa, Parallel and Keenable (search APIs designed for LLM consumption), Brave Search API and Serper (independent or Google-backed SERP results), You.com, and Perplexity Sonar (search bundled with an answer model). Which one fits depends on whether you want raw results to feed your own model, full page text, or a finished answer. Mux lets you try Exa, Parallel and Keenable with a single key and fall back between them, which is a practical way to evaluate three of the seven at once.
Tavily is a solid product and many teams should stay on it. This page is for the cases where price, latency, index freshness or a specific feature pushes you to look around.
What Tavily does well#
Tavily positions itself as a search engine built for AI agents, with search, extract and crawl endpoints and integrations in the common agent frameworks. As of October 2026 its pricing page lists a free tier of 1,000 API credits per month and a pay-as-you-go rate of $0.008 per credit, with a basic search costing 1 credit and an advanced search 2 credits. That works out to $8 per 1,000 basic searches or $16 per 1,000 advanced searches on pay-as-you-go. Monthly plans are priced differently, so check the page for your volume.
Staying on Tavily is sensible when:
- You rely on its extract or crawl endpoints as well as search. Mux offers neither.
- Your volume fits inside the free tier or a monthly plan that works out cheaper for you.
- You have framework integrations already wired to it and the switching cost outweighs any saving.
The alternatives#
Exa#
Exa is a neural search engine with an index built for semantic queries, which makes it strong on research-style questions where keyword search struggles. Through Mux, exa/auto costs $7.00 per 1,000 requests and exa/instant $4.00, with results up to 100 per request and full page text available with content: "full". Exa also sells directly at exa.ai, including endpoints Mux does not proxy.
Parallel#
Parallel's search API is built for agents and prices aggressively at the low end: parallel/turbo and parallel/fast are $1.00 per 1,000 requests through Mux, and the higher-quality parallel/basic and parallel/advanced are $5.00. Results max out at 50 and content: "full" returns joined excerpts rather than whole pages. Direct access is at parallel.ai.
Keenable#
Keenable runs its own index and offers a pro and a realtime variant. Through Mux both are $4.00 per 1,000 requests with no charge for extra results up to 50, which makes it the cheapest option when you want many results per query. It does not return page content. See keenable.ai for direct access.
Brave Search API#
Brave operates an independent web index and sells API access to it. As of October 2026 its API page lists a Search plan at $5 per 1,000 requests with $5 in free credits per month and a 50 queries per second rate limit, plus an Answers plan with grounding and citations. Brave is a good fit if you want results from an index that is not Google's or Bing's and you are comfortable integrating one vendor directly.
Serper#
Serper returns Google search results as JSON, including organic results, knowledge graph, People Also Ask and vertical searches like news, images and scholar. Its site advertises 2,500 free queries on signup. If your agent needs to see what Google shows, this is the direct route. For current per-query rates see their pricing page.
You.com#
You.com offers web search APIs aimed at AI applications and gives new organizations starter credit to evaluate. It is a reasonable option if you want an LLM-oriented index from a vendor that also runs a consumer product. See you.com for current pricing.
Perplexity Sonar#
Sonar is different in kind: it is an answer model with built-in search, billed per request plus per token. As of October 2026 Perplexity's pricing page lists sonar at $5 to $12 per 1,000 requests depending on search context size, plus $1 per million input and output tokens. Pick Sonar when you want a finished, cited answer rather than results to feed your own model.

Try three providers with one key#
A common complaint when evaluating search APIs is that you have to sign up three times and write three adapters before you can compare anything. Mux normalizes Exa, Parallel and Keenable behind one endpoint, so switching the provider is a one-string change and the response shape stays the same.
curl -X POST https://api.getmux.io/v1/search \
-H "Authorization: Bearer $MUX_API_KEY" \
-H "Content-Type: application/json" \
-d '{"query": "rust async runtime comparison 2026", "model": "exa/auto", "max_results": 5}'Once you know which provider you prefer, keep the others as fallbacks. The models field takes an ordered list, failed attempts are refunded, and you pay only for the model that answered:
{
"query": "rust async runtime comparison 2026",
"models": ["parallel/fast", "exa/auto", "keenable/pro"],
"max_results": 10
}Each API key can carry a USD limit that resets daily, weekly or monthly, which is useful when you give each agent or each engineer their own key during an evaluation. See /docs/keys.
When Mux is the wrong choice#
Mux is a router over three providers. If the provider you want is Brave, Serper, You.com or Perplexity, go to them directly. If you depend on Tavily's extract or crawl, or any vendor's crawl or contents endpoint, Mux does not replace that. And at very high sustained volume on a single provider, a negotiated direct contract may beat list price.
FAQ#
What is the cheapest Tavily alternative for high-volume agent search?#
Among the providers covered here, Parallel's parallel/fast and parallel/turbo at $1.00 per 1,000 requests through Mux are the lowest list price. Compare that against Tavily's pay-as-you-go rate of $0.008 per credit as of October 2026, which is $8 per 1,000 basic searches. Monthly plans and free tiers change the math at low volume.
Which alternatives return full page content?#
Exa returns full page text with content: "full". Parallel returns longer excerpts. Tavily offers page text through a separate extract endpoint. Keenable, Brave and Serper return results and snippets without full pages.
Can I switch from Tavily to Mux without rewriting my agent?#
The request shape is different, so you will change the call site, but it is one endpoint with query, max_results, domain and date filters, and results as {title, url, snippet, content, published_date}. The TypeScript and Python SDKs are a few lines each. You keep the ability to change providers afterwards without touching code again.
Is Mux affiliated with Tavily, Exa, Parallel or Keenable?#
No. Mux is an independent service launched October 13, 2026. Exa, Parallel and Keenable are trademarks of their owners, and Mux passes through their list prices.
