Guardian vs Tavily: search API pricing and agent retrieval tradeoffs
Tavily is built around AI retrieval workflows rather than a plain SERP contract. Its Search API can rank and process web content for agents, while its broader product includes Extract, Crawl, and Map. Guardian stays closer to a lower-cost search layer with multiple verticals and a shared REST, SDK, and MCP account.
Guardian pricing
Guardian charges one credit per started block of 10 requested search results. The effective rates below assume each search requests 10 results or fewer and the included monthly credits are fully used.
| Plan / mode | Price | Included | Effective search price |
|---|---|---|---|
| Free | $0 | 1,000 credits | $0No card required. |
| Developer | $49/mo | 25,000 credits | $1.96 / 1KUp to 10 results uses 1 credit. |
| Growth | $249/mo | 200,000 credits | $1.245 / 1KUp to 10 results uses 1 credit. |
| Scale | $999/mo | 1,000,000 credits | $0.999 / 1KUp to 10 results uses 1 credit. |
Tavily search pricing
| Plan / mode | Price | Included | Effective search price |
|---|---|---|---|
| Researcher | $0 | 1,000 credits/mo | $0Basic search uses 1 credit; advanced uses 2. |
| Pay as you go | $0.008/credit | Usage based | $8 / 1K basicAdvanced search is $16 / 1K at 2 credits per call. |
Tavily says Basic Search costs 1 credit and Advanced Search costs 2 credits. Its current pricing page lists pay-as-you-go credits at $0.008 each and also offers adjustable monthly plans; check Tavily's live pricing page for the current plan quote.
Guardian is cheaper on straightforward search volume
At Tavily's $0.008 pay-as-you-go credit rate, 1,000 Basic searches cost $8 and 1,000 Advanced searches cost $16. Guardian's ten-result search rate ranges from about $1.96 per 1,000 on Developer to about $0.999 on Scale.
Tavily also offers adjustable monthly plans, so a committed plan can reduce the effective cost per credit below the pay-as-you-go rate. The live pricing page should be used for the current plan quote rather than assuming the pay-as-you-go number applies at every volume.
Tavily does more retrieval work inside the call
Tavily's Basic Search returns relevance-ranked results and processed snippets. Advanced Search is designed for deeper retrieval and can return more query-aligned content chunks. Tavily also offers Extract, Crawl, and Map as separate web-data operations.
Guardian's advantage is a smaller billing unit for search and a search surface that covers multiple engines and verticals. If your application already has its own extraction, reranking, or RAG pipeline, paying primarily for search can be attractive.
If Tavily's processed content saves an extraction pass or improves task success enough to avoid repeated searches, its higher per-call rate can still produce the lower cost per completed task.
Use a task benchmark, not a ten-query demo
Test Basic and Advanced Tavily separately. They are different products at different credit costs. Compare each against Guardian using the same production questions, the same downstream model, and the same task completion criteria.
Track search calls, extracted pages, model tokens, latency, and the number of tasks that finish without human correction. That reveals whether the extra retrieval work Tavily performs is worth the extra credits for your application.
Which one fits your workload?
Choose Guardian when
- You already own the content extraction or RAG layer and mainly need inexpensive search results.
- You use several web verticals and want them behind one search contract.
- You want REST, TypeScript SDK, and MCP access with one Guardian API key.
- Lower search cost matters more than built-in crawl, map, and extraction features.
Choose Tavily when
- You want search results already shaped for AI retrieval and are willing to pay for Advanced Search when needed.
- You also need Tavily Extract, Crawl, or Map and prefer one web-data vendor.
- Your task benchmark shows Tavily reduces follow-up searches or downstream extraction enough to offset its higher search price.

The business API uses scoped API keys, monthly quotas, usage headers, and the same account across REST, the TypeScript SDK, and MCP.
Frequently asked questions
Is Guardian cheaper than Tavily?
On published raw search pricing, yes. Tavily PAYG is $0.008 per credit, with Basic Search at 1 credit and Advanced Search at 2 credits. Guardian's paid ten-result search rate is about $0.999 to $1.96 per 1,000 searches.
Why does Tavily cost more per search?
Tavily is built as an AI retrieval layer and offers processed content plus deeper Advanced Search, along with Extract, Crawl, and Map APIs. Those features can replace work that would otherwise happen after a basic search call.
Does Guardian crawl websites?
Guardian's business product is centered on search rather than whole-site crawling. If crawling and page extraction are core requirements, Tavily or Firecrawl may fit that part of the stack better.
