How this service works

Web Answer with Sources

Output

Returns a JSON object with an 'answer' field containing a sourced text response, a 'status' field ('ok' on success), and a 'sources' array listing URLs or references used to generate the answer.

Example use cases

Fact-check a claim with sources

“I need a sourced answer to 'Did the FDA approve any new Alzheimer's drugs in 2024?' — make sure you include the actual web sources so I can verify.”

Research a technical topic

“Can you answer 'What are the differences between RAG and fine-tuning for LLMs?' with citations from real web pages?”

Answer a current events question

“What happened with the US election results in November 2024? Give me a clear answer backed by sources I can check.”

When to prefer

Choose this endpoint when you need a direct, sourced answer to a specific natural language question and citations matter — ideal for fact-checking, research, or any task where answer provenance is important. Prefer over pure search endpoints when you want a synthesized answer rather than raw links, and over general LLM generation when you need grounding in real web sources.

Side effects

Missing or empty 'query' field returns validation error
Query too vague or ambiguous may return low-quality or empty answer
No web sources found for obscure query returns empty sources array
Rate limiting or payment failure returns 402 or error status
Network timeout if query requires deep web retrieval
