  "account": "Amazon has announced new capabilities for Web Search on its AgentCore platform - runtime domain and published-date filtering. This allows developers to control precisely which web domains an AI agent can search and limits results to a specific publication-date window, enforced server-side.\n\nThese features are particularly useful for specialized agents. A financial services agent should avoid unvetted blogs, while a product information agent shouldn't cite out-of-date pricing data. Runtime filtering lets developers specify which domains can be accessed on a per-request basis.\n\nThe domain filtering allows an allowlist or denylist of up to 100 domains per request. Once combined with the existing admin-level domain policies, organizations get a layered filtering model that balances enterprise governance with per-request flexibility.\n\nIn addition to runtime filtering, Web Search is now available in two new AWS regions - Dublin and Tokyo. This enables regulated customers to run grounded agents closer to their workloads, reducing latency and providing EU-based access points.\n\nBoth the admin and runtime filters are enforced server-side within Amazon's zero-egress architecture. There is no client-side filtering or extra round trips. The admin-level policies are set when creating the connector resource, while runtime filters are included in each tools/call request.",
  "summary": "Web Search on Amazon Bedrock AgentCore now supports runtime domain and published-date filtering. New per-request filters give developers per-call control over which web sources their agents consult and how fresh those sources must be, all enforced server-side. This release also expands Web Search to the Europe (Ireland) and Asia Pacific (Tokyo) Regions.",
