# Linkup review (2026): is the free plan enough?

> Pay-per-request web search and fetch API for AI agents

Checked Nov 12, 2026 · graded Nov 12, 2026 by ToolGPA.

Linkup is an API that gives AI agents and applications web search, page fetching and asynchronous deep research. It bills each successful request against a prepaid account balance instead of selling monthly plans, and it publishes the per-request price of every endpoint and depth setting.

- **Category:** SERP & SEO Data APIs
- **Made by:** Linkup
- **Website:** https://www.linkup.so
- **Runs on:** Web
- **Who should skip it:** Not for you if you want a fixed monthly bill, since spend follows usage.
- **Facts last checked:** Nov 12, 2026

## Key features

- **Search endpoint:** Web search for agent tool calls. Flash, fast and standard depths cost $0.005 a call and deep costs $0.05 for raw results.
- **Sourced answers and structured output:** The search endpoint can return a sourced answer or output shaped to a schema, at $0.001 to $0.005 more than raw results.
- **Fetch endpoint:** Gets a URL's content as Markdown, from $0.001 per call without JavaScript rendering up to $0.01 with pro mode and rendering.
- **Research endpoint:** Asynchronous deep research billed by reasoning depth: $0.25 for S, $0.50 for M, $1.50 for L and $2.50 for XL.
- **Agent integrations:** Docs cover an MCP server and guides for LangChain, LlamaIndex, CrewAI, the Vercel AI SDK and Composio.

## Good for

- Developers who want to pay per request with no subscription
- AI agents that need search, fetch and research behind one API
- Teams moving off another search API, with docs on migrating from Tavily, Exa and SerpAPI

## Worth knowing

- There is no monthly plan: each successful call draws down a prepaid balance, so spend follows usage.
- The pricing page says 'Run 4,000 queries for free'; the docs describe it as $20 of credit, which covers 4,000 searches at $0.005.
- Zero-data retention is offered only on the Enterprise plan; SOC 2 Type II is stated to be on all plans.
- It is a general web search API, not an SEO tool: it has no rank tracking or keyword data.

## ToolGPA grades

**GPA: 2.4 out of 4**, graded Nov 12, 2026. Linkup is a web search API for AI agents with sourced answers, a fetch endpoint and a research endpoint. There is no monthly plan, so you pay per call from a prepaid balance, and the free $20 credit needs a professional email.

- **Value for money: C.** Pay per call from a prepaid balance at about $0.005 a search, with no flat plan to compare with this category's $19 to $44.
- **Free plan and trial: B.** $20 of credit on sign-up, topped back up to $20 each month for eligible accounts, about 4,000 searches. One person could live on that.
- **Features: C.** Search, sourced answers, fetch and research endpoints. Zero data retention is only on the Enterprise plan.
- **Ease of use: C.** No store rating on record. It is an API with a key and code to write.
- **Platforms and integrations: B.** Web only, but it lists LangChain, LlamaIndex, CrewAI, Vercel AI SDK, Composio, Hugging Face and Agno.

## Keep it, or make your own?

**Keep it.** To replace Linkup you would be making search results fetched at scale from many countries without being blocked. That is not a weekend's work, with an AI app builder or without one.

- You could not: Search results fetched at scale from many countries without being blocked.
- You could not: A search engine with an AI model behind it.
- You could not: A library of papers and sources to search.
- You could not: An AI agent, with the models and the safeguards behind it.
- You could not: It plugs into other products, LangChain, LlamaIndex and CrewAI among them, and has an API.

A judgement by ToolGPA from this listing, by rules that are the same for every tool. Nothing was built to test it.
