# Exa

Best live-web search API here for agents that need ranked results, long page text, and cited answers.

## TL;DR Verdict

**Best overall in this benchmark**

**Where it wins:**
- you are building an agent, chatbot, research tool, or open-web RAG layer
- you need both search results and a direct answer mode, scored separately
- you care about current facts, freshness, and long extracted page text

**Main limitation:** you need a consumer search UI instead of an API

**Pricing:** /search $7.00 / 1k calls · /answer $5.00 / 1k calls

`92.3% answers correct` · `57.4% top-3 search` · `38.6k chars/result` · `0.3% false citations`

> **Best overall in this benchmark**
>
> Exa is the strongest all-around choice in this benchmark. \`/search\` is the most reproducible of the former top three and best on current-fact retrieval, \`/answer\` is the best direct-answer mode at 48/52, and both modes return long extracted page text with measured cost. The caveats are real: answer-mode ambiguity is weaker, Q43 shows a correct answer with a false citation, and the billing-dashboard allowance still needs a direct capture.

## Feature-by-Feature Breakdown

### Live Web Search with Extracted Page Content — 27/47

**Verdict:** Top-3 tied-best overall, strongest on current-fact queries.

Exa's `/search` mode takes a plain query string and returns ranked live-web results with titles, URLs, extracted page text, published dates, and per-call cost metadata. The returned page text is often long enough to use directly instead of just a snippet.

**Input:** Ground truth query set

> **Csv** — Ground truth query set

**Output:** Scored run export

> **Csv** — Scored run export

**Input:**

```
Q26 ambiguity probe: the query "Sonar" should resolve to Perplexity, not SonarSource.
```

**Output:** Per-query output

> **Md** — Per-query output

**Input:**

```
Q43 current-fact / freshness probe: Python 3.11.16 release details.
```

**Output:** Per-query output

> **Md** — Per-query output

**Input:**

```
Q36–Q41 content-depth block: answer-bearing figures buried deep in long pages.
```

**Output:** Verification summary

> **Md** — Verification summary

**Bottom line:** Use `/search` when you want reproducible retrieval and long extracted text; it is excellent for current facts, but it is not a substitute for opening the citations.

### Cited Answer Synthesis — 48/52

**Verdict:** Best direct-answer mode, with citation checks still required.

Exa's `/answer` mode takes a query and synthesizes a direct cited answer rather than just returning ranked results. It was strongest on freshness and multi-source answers, though the citations still need verification.

**Input:**

```
Q43 answer-grade check: Python 3.11.16 release details.
```

**Output:** Answer grades

> **Csv** — Answer grades

**Input:**

```
Q43 citation-honesty check: Python 3.11.16 release details.
```

**Output:** Citation verdicts

> **Csv** — Citation verdicts

**Input:**

```
Q49 unanswerable query: Jina AI acquisition / financials not separately disclosed.
```

**Output:** Per-query output

> **Md** — Per-query output

**Input:**

```
Q52 unanswerable pricing query.
```

**Output:** Per-query output

> **Md** — Per-query output

**Bottom line:** Use `/answer` when you want a direct answer rather than a results list, but treat the citation as something to verify rather than trust blindly.

## Measured endpoint rates

Exa bills by credits in its docs; the benchmark measured the public per-call rates directly.

| Plan | Price | Notes |
| --- | --- | --- |
| /search ★ | $7.00 / 1k calls | 52-query run cost: $0.364; 0 errors. |
| /answer | $5.00 / 1k calls | 52-query run cost: $0.260; 0 errors. |

*Exa's docs say $20 on signup and $10/month in credits with no payment method required. Third-party trackers reported a free-tier change from 1,000 to 20,000 requests/month on 2026-07-14, but the August billing-dashboard allowance was still not captured here.*

## Is It Right For You?

**Use it if**
- you are building an agent, chatbot, research tool, or open-web RAG layer
- you need both search results and a direct answer mode, scored separately
- you care about current facts, freshness, and long extracted page text
- you want measured latency and cost instead of vendor claims

**Skip it if**
- you need a consumer search UI instead of an API
- you need known-URL scraping, not query-in retrieval
- you need private-document RAG
- you need ambiguity-heavy answer mode without checking citations
- you need the August billing-dashboard allowance before budgeting

## Frequently Asked Questions

**Q: Does Exa separate search and answer modes?**

Yes. The research tested `/search` and `/answer` separately, and they failed differently: `/search` was stronger for retrieval quality and reproducibility, while `/answer` was the best direct-answer mode overall.

**Q: How accurate were Exa's citations?**

Exa had 1 false citation in the checkable set, or 0.3%, which was the second-best result. The clearest case was Q43: the answer grade was correct, but the citation pointed to aiohttp v3.11.16 release notes for a Python 3.11.16 question.

**Q: Does Exa return full page text or just snippets?**

It returns long extracted page text. The report says the median result was about 38,600 characters, and published dates appeared on 94% of results.

**Q: What did Exa cost and how fast was it?**

`/search` measured $7.00 per 1k calls, with 2,879 ms p50 and 3,791 ms p95. `/answer` measured $5.00 per 1k calls, with 3,237 ms p50 and 3,823 ms p95.

**Q: What is Exa's free tier?**

Exa's own docs describe credits, not a request-count free tier: $20 on signup and $10/month in credits with no payment method required. Third-party trackers reported a change from 1,000 to 20,000 requests/month on 2026-07-14, and the report still says the August billing-dashboard allowance was not captured.
