# Web research

Investigate public information and keep the findings connected to their sources.

## Ask a focused question
Give the agent a question, scope, and freshness requirement. Identify sources you consider authoritative and ask for links supporting the conclusions.

> Compare the published return policies of these three suppliers. Use their official websites, link to each policy, and flag any terms you cannot verify.

Opser can fetch public pages, search, and scrape supported content. A managed browser can inspect rendered public pages when simpler methods cannot read them.

## Browser research has a specific scope
The browser research capability is read-only. It investigates public pages and can expose a live preview when available. It does not log into accounts, submit forms, send messages, place orders, or make purchases.

Use a supported [integration](https://docs.opser.com/agents/integrations/) for authorized account operations. Browser interaction used while testing an agent-built app is a separate app-building capability.

## Evaluate the answer
Check that cited sources support the claims and that the dates are appropriate. Ask the agent to distinguish facts from inference and to report conflicting evidence. A page may be blocked, removed, region-specific, or incomplete.

## Costs and limits
Search, scraping, and managed browser research can have different usage costs. The agent should use an appropriate method for the task; opening a complex page in a managed browser may consume more than a straightforward fetch. Inspect [Usage](https://docs.opser.com/billing/usage/) for the work performed.
