How this service works
Ask a question, get a direct answer grounded in a live web search, with numbered citations (title, url, published_date). One call replaces search + read + summarize. For ranked results instead of a synthesized answer use /exa/search. Keyless x402, pay per call on Base or Solana.
Output
A JSON object containing the original query, a synthesized prose answer with inline citation markers (e.g. [1][2]), an array of citation objects (each with index, title, URL, author, published_date, and optional source text), the citation count, and the provider name (exa). The answer integrates information from multiple live web sources into a single coherent response.
Example use cases
Real-time competitor intelligence
“What has OpenAI announced in the last 30 days? Give me a concise answer with links to the original sources.”
Fact-checking a claim
“Is it true that the US Federal Reserve raised interest rates in 2025? Search the web and give me a direct answer with citations so I can verify.”
Research briefing on emerging topic
“What is the x402 payment protocol and how does it work? Pull a grounded answer from the live web with numbered references.”
Technical details
Endpoint
GEThttps://netintel.dev/exa/answerWhen to prefer
Choose this endpoint when you need a single synthesized answer grounded in live web data, with citations, in one call — replacing a manual search + read + summarize pipeline. Prefer it over /exa/search when you want a direct answer rather than a ranked list of URLs. Ideal for factual Q&A, research briefings, real-time fact-checking, and any task where provenance (source URLs and dates) matters. Best when the question is well-formed and specific enough to produce a meaningful synthesis.
Side effects
- Missing or empty `query` parameter returns a validation error
- Query shorter than 3 or longer than 1000 characters is rejected
- Payment not included or insufficient funds results in HTTP 402 response requiring x402 payment
- No relevant web results found may return a low-confidence or empty answer
- Rate limiting or upstream Exa API unavailability causes service errors
- `include_citation_text` flag with more than 5 citations returns truncated text at 800 chars per source
