Skill: Answer-a-question with
POST https://agent402.tools/api/skill/search-and-cite
Bundled execution of the Answer-a-question with sources workflow - The 'research a question, return an answer with citations' workflow. Brave answer for the AI-synthesized take with citations, Brave web for the canonical SERP, Brave news for time-sensitive context, then a deterministic web-fetch + extract pass on the top citations to verify the answer hasn't hallucinated. Five tools, one cited paragraph, every claim traced back to a fetched URL.
