Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.2
GPA, above 7 of the 49 other AI research tools we grade
Exa is a search API that returns web results, page contents and agent-run research for AI applications. Its index includes web, people, company and scholarly-works data. Developers start on a free monthly credit allowance and then pay per request.
To get you started, here are 8 things to know about Exa, taken from its own pages and our grades.
You need code, an API key and a client to use it, so it's a D.
- 1
Best for giving AI agents a web search API
Exa is a web search API for developers building AI agents, with search, page contents, monitors and agent endpoints.
- 2
There is a free plan
Starter: $10 in credits every month plus a $10 onboarding bonus, no payment method required.
- 3
It runs on Web
Web.
- 4
Search API
Returns web results with page text and highlights, with latency settings from about 450 ms to 10 seconds and categories such as news, companies, research papers and people.
- 5
Contents API
Fetches full page contents or token-efficient highlights for use as model context, with configurable live-crawl policies.
- 6
Agent API
Runs asynchronous deep-research tasks that return structured output with citations.
- 7
A 2.2 GPA, above 7 of 49
That is against the other AI research tools we grade, on value, the free plan, features, ease of use and platforms.
- 8
Keep it
To replace Exa you would be making a search engine with an AI model behind it. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for giving AI agents a web search API
Exa is a web search API for developers building AI agents, with search, page contents, monitors and agent endpoints. The free Starter gives $10 in credits a month, but past that you pay per request, so it's a developer product with no reading or note-taking app.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | No fixed monthly price: search from $4 per 1,000 requests, contents $1 per 1,000 pages and agent runs $0.012 to $1.00 each. It's a different kind of thing from a reading app, so it sits at C, and the bill depends on usage. |
| Free plan and trial | B | The Starter plan is $10 of credits every month plus a $10 onboarding bonus, with no payment method needed. A solo developer testing can live on that. |
| Features | C | Search, Contents, Agent and Monitors APIs plus agent tooling. A developer building block rather than a research tool, and zero data retention needs a $12,000 annual Enterprise commitment. |
| Ease of use | D | No store rating on record. You need code, an API key and a client to use it, so it's a D. |
| Platforms and integrations | B | Web API with Claude, ChatGPT and MCP hooks. No desktop or mobile apps, as the listing says. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Exa is for
- Fits if you're building an AI agent that needs to search the live web
- Works for developers who want search results returned as page contents
Who it is not for
- Not for you if you want an app to read or take notes in, as it's an API
- Tight if you go past $10 of credits a month, when billing is by usage with no fixed price
- Pricey if you need zero data retention, which is Enterprise with a $12,000 annual credit commitment
- Watch out: Starter allows 10 searches per second and 50 agent concurrency
Good to know
Good for
- Developers adding web search to an AI agent or chatbot
- Teams that want scholarly and company data behind one API
- Builders who want to start free before paying per request
Worth knowing
- The free Starter allowance is $10 of credits per month; past that, the Developer plan bills by usage with no fixed monthly price.
- Per-request prices: search from $4 per 1,000 requests, contents $1 per 1,000 pages, monitors $2 per 1,000 requests, agent runs $0.012 to $1.00 each.
- Zero data retention is an Enterprise option with a $12,000 annual commitment in API credits.
- It is an API for developers, not a reading or note-taking app; it has no desktop or mobile apps.

Where it stands
Its grades against its category, and whether to keep it or make your own
7/49
Other AI research tools it is graded above
Exa's GPA of 2.2 is higher than 7 of the 49 other AI research tools we grade, and level with 11.
It stands best on free plan and trial (B, above 36 of 49) and worst on ease of use (D, above 0).
Each grade against the category
Every bar is all 50 AI research tools we grade, cut by the letter each got. Exa’s own letter is outlined.

- BPlatforms and integrationsAbove 16 of 49
Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Exa you would be making a search engine with an AI model behind it. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 31 of the 49 other AI research tools grade higher.
What you could not
- A search engine with an AI model behind it.
- A library of papers and sources to search.
- An AI agent, with the models and the safeguards behind it.
- It plugs into other products, Claude, ChatGPT and MCP among them, and has an API.
What this rests on. Exa’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
