How this service works
Exa neural web search for AI agents — POST or GET a query, get ranked live results (title, url, published_date, author, score) with optional highlight snippets. Filter by category (news, research paper, github, company, pdf…), domain include/exclude, and publish date. For a direct answer use /exa/answer. No API key, pay per call on Base or Solana.
Output
Returns a JSON object containing the original query, provider name ('exa'), search type used, number of results, and an array of result objects each with url, title, published_date, author, relevance score, optional highlight snippets, and optional full text — plus an empty findings array for future use.
Example use cases
Track breaking AI industry news
“Search for the latest news articles about large language model releases from the past two weeks and give me the top 5 results with highlight snippets.”
Find academic research on a topic
“Find recent research papers about retrieval-augmented generation published after January 2025 — I want up to 10 ranked results with their URLs and publication dates.”
Discover GitHub repos for a technology
“Search GitHub for open-source repositories related to the x402 HTTP payment protocol and return the top 5 results with their scores.”
Technical details
Endpoint
GEThttps://netintel.dev/exa/searchWhen to prefer
Choose this endpoint when you need live, ranked web search results with neural (semantic) relevance scoring rather than pure keyword matching — especially when filtering by content category (news, research papers, GitHub, PDFs), restricting to specific domains, or needing recent content by publish date. Prefer this over static knowledge bases when freshness matters. Use /exa/answer instead if you want a synthesized direct answer rather than a list of sources.
Side effects
- Missing required 'query' parameter returns a validation error
- Query longer than 1000 characters is rejected
- num_results > 10 is silently clamped to 10
- snippets mode with more than 2 results is clamped to 2
- Invalid category value may return no results or an error
- Invalid ISO 8601 date format for date range filters returns an error
- Payment failure (insufficient USDC balance) returns a 402 error
- Network or Exa upstream outage returns a 5xx error
