AWS launches Web Answer for Amazon Bedrock AgentCore
AWS Machine Learning Blog reports that Web Answer is now generally available as a managed Amazon Bedrock AgentCore Gateway tool. It accepts a natural-language question and, according to AWS, plans parallel web searches, verifies facts on pages, and returns a synthesized answer with source citations in seconds. It is available in US East (N. Virginia), priced at $10 per 1,000 tool calls, with a per-account limit of 10 transactions per second.
AWS says Web Answer consolidates search, retrieval, synthesis, and attribution into one MCP-compatible tool call, reducing the pipeline that agent developers otherwise need to build and maintain.
Today, we are announcing the general availability of Web Answer on Amazon Bedrock AgentCore. With Web Answer, agent builders get a synthesized, source-cited answer to a natural-language question with a single tool call. They no longer build a search, retrieve, synthesize, and citation pipeline themselves.
If you have built agents that need to answer questions from current web sources, you know the pattern: call a search API, decide which results to trust, retrieve and clean page content, prompt a model to synthesize, and engineer citation extraction so the output traces back to a source. Every step is code you maintain, and every step is another place things can go wrong: hallucination when evidence is insufficient, stale content when the index moves, and broken attribution when a claim and its source drift apart.
The Web Answer collapses that entire pipeline into one request. You send a question. You get back a cited answer in seconds. In this post, we explain what Web Answer does, compare it with Web Search on AgentCore, show how it works and what it returns, and walk through adding Web Answer to a gateway and calling it from an agent.
