Exa

What Exa helps you do

Exa provides search and content APIs for applications that need relevant web documents. It suits developer research, company discovery or retrieval workflows with a defined question and source checks.

Best for: Semantic web search in developer applications.

A small task to try

1. Create a development project with a private API key
2. Search for official documentation on a narrow technical question
3. Fetch the most relevant result and record its URL
4. Check publication context and whether it answers the exact question

Illustrative input: Find documentation explaining the difference between model context length and maximum output tokens.

Illustrative expected result: Source records that define both terms, with separate citations rather than an unsupported blended answer. This is an editorial example, not a recorded vendor test. Check it against your original material before using it.

Access and buying guidance

The free tier lists USD 10 in credits/month plus onboarding credits, with no payment method required. Pay-as-you-go and larger plans apply after limits; endpoint rates vary.

A relevant result is not automatically an authoritative source. Start with the smallest useful task; keep the original input and compare the result before committing to a larger workflow.

Alternatives for a different workflow

Perplexity: research interactively instead of integrating an API. Consensus: focus on scholarly evidence rather than the wider web.
