How this service works
SingIt Search: A cited answer to a question, from Exa. Call it when an agent needs a sourced answer rather than raw search results, with no API key or account.

Returns an AI-synthesized answer to the query along with cited source URLs, drawn from live web results via Exa's answer API. Nothing is charged if no answer is returned.
Example use cases
Real-time fact check with sources
“Can you search the web and give me a cited answer on whether Ozempic has been approved for adolescents in the EU? I need the source URLs too.”
Current events research briefing
“Search the web for the most recent updates on the US-China trade negotiations in 2025 and summarize what you find with citations.”
Technical question with live documentation

Endpoint
POSThttps://ask.singitai.app/v1/exa/answer?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a cited, AI-synthesized answer grounded in current web content and you want pay-per-use pricing with no API key or subscription. Prefer it over raw web search when you need a synthesized answer with source attribution rather than a list of URLs. Prefer it over LLM-only answers when freshness and citation are required. The x402 micropayment model (0.01 USDC on Base) makes it economical for infrequent or agent-driven searches.
Side effects
- No answer found – no charge is applied
- Invalid or malformed Exa request body
- Insufficient USDC balance or x402 payment failure
- Rate limiting or upstream Exa API error
- Network timeout on complex queries
