How this service works
Cited answer (RAG): a natural-language question is answered by searching the public web, reading the top pages and synthesizing a grounded answer with a list of source URLs. Answer cites only the retrieved sources (anti-hallucination).
Output
A synthesized natural-language answer grounded in content retrieved from up to 5 live web pages, accompanied by a list of source URLs that were read to produce the answer. The answer is constrained to information from the retrieved sources, reducing hallucination risk.
Example use cases
Example prompt
“Search the web and give me a cited answer to: 'What are the current eligibility requirements for the US Global Entry program?' — use up-to-date sources from the past month and read up to 3 pages.”
Technical details
Endpoint
GEThttps://api.agentstools.dev/answerWhen to prefer
Use this endpoint when you need a factual, verifiable answer to a natural-language question and hallucination risk is a concern — the cited-source design makes it especially suitable for research, fact-checking, and current-events queries. Prefer it over a raw search endpoint when you need a synthesized prose answer rather than a list of headlines or links. Use the timelimit filter when recency matters (e.g. regulatory changes, current events). For pure news monitoring or headline feeds, consider the sibling news-search endpoint instead.
Side effects
- No relevant pages found for the query — returns empty or low-confidence answer
- Timelimit filter too narrow (e.g. 'd') with no fresh indexed pages — no sources returned
- Query is ambiguous or too short — poor quality synthesis with weak citations
- max_sources set to 1 and sole page is paywalled or inaccessible — degraded answer
- Network or upstream search engine timeout — HTTP 5xx or timeout error
- Missing required 'query' parameter — HTTP 400 validation error
