How this service works

Exa Answer - Get AI-generated answers with citations

Output

Returns a JSON object containing a synthesized AI-generated answer string, an array of citation objects (each with URL, title, text snippet, author, published date, favicon, and image), and a cost breakdown object with total dollar amount.

Example use cases

Example prompt

“What are the main causes of the 2008 financial crisis? I need a thorough answer with citations so I can verify the sources.”

Technical details

Endpoint

POSThttps://stableenrich.dev/api/exa/answer?utm_source=zero.xyz

When to prefer

Use this endpoint when you need a concise, AI-generated answer to a specific question that is grounded in real web sources with verifiable citations. Prefer it over a raw search endpoint when you want synthesis rather than a list of links, and over a scraping endpoint when you want question-answering rather than raw page content. Ideal for research, fact-checking with sources, or any task where the agent needs both an answer and the evidence behind it.

Side effects

Empty or missing query returns 400 validation error
Query too vague or unanswerable may return a low-confidence or empty answer
Network timeout if upstream Exa service is unavailable
Payment failure if USDC balance is insufficient
Citations array may be empty if no relevant sources are found
Rate limiting if too many requests are made in quick succession

Input

{
  "query": "What are the main benefits of renewable energy sources?"
}

  "answer": "Renewable energy offers several primary benefits, centered on environmental and economic stability. These sources are naturally replenished, making them inexhaustible compared to finite fossil fuels [1][2][3]. By generating little to no greenhouse gases or air pollutants, they mitigate climate change and significantly improve public health by reducing respiratory and cardiovascular risks associated with fossil fuel emissions [1][3][4]. Economically, renewables are increasingly the most affordable power source, creating more jobs per unit of electricity than fossil fuels [5][3][4]. Additionally, they enhance energy security and resilience by reducing dependence on imported fuels and mitigating exposure to volatile global market prices [2][3][4].",
