Exa API review
Largest free tier
Exa searches its own index semantically rather than reporting Google's rankings, which makes it a different tool from everything else in this directory. You describe the kind of page you want and it finds pages like that, which is closer to how research works than how rank checking works.
For SEO the use case is content and competitive research rather than measurement: finding every page covering a topic, surfacing what competitors have published, feeding a model a corpus. Its 20,000 free requests a month is the largest free allowance here by a wide margin.
Who Exa API is for
Teams building AI-assisted research or content workflows, where semantic relevance matters more than Google's ordering. It is not a rank tracking tool and should not be treated as one.
Strengths and limits
What it does well
- 20,000 free requests a month, an order of magnitude beyond any other free tier in this directory.
- Neural search finds semantically relevant pages that a keyword query would miss entirely.
- Full page contents available alongside results, so research and retrieval are one call.
- Pure pay as you go with no minimum and no subscription.
Where it falls short
- Not Google. Results reflect Exa's own index and ranking, so it cannot answer where you rank.
- No SEO metrics at all: no volume, no difficulty, no backlinks.
- Deep Search costs $12 to $15 per 1,000, well above the base rate.
Exa API pricing
Search is $7 per 1,000 requests returning up to 10 results, then $1 per 1,000 for each additional result. Page contents are $1 per 1,000 pages and Deep Search is $12 to $15 per 1,000. Twenty thousand requests a month are free.
That free tier is the headline. For most research workloads you may never pay, which is not something any other provider here can claim.
Verdict
Not an SEO measurement tool, and genuinely useful anyway. For content research, competitive sweeps and feeding models a relevant corpus, the semantic index does things a SERP API cannot. The free tier makes it near-costless to add alongside whatever you already use.

No. It searches its own index semantically rather than reporting Google's results, so it cannot tell you where you rank. Use it for research and a SERP API for measurement.What is neural search?
Search by meaning rather than keyword match. You describe the kind of page you want and it returns semantically similar pages, which surfaces relevant results that exact-match querying would miss.Exa or Tavily?
Close on raw search cost, around $7 to $8 per 1,000. Exa has a far larger free tier at 20,000 requests a month against Tavily's 1,000 credits, and is pure pay as you go. Tavily is more tuned to agent answer workflows.
