Enables free-first web search in English and Chinese with no API key required, returning compact multi-source evidence while keeping provider failures, stop reasons, and budget limits visible. Optional paid providers are used only when routing policy and credentials allow.

Enables English and Chinese web search through zero-key sources, plus optional paid providers under an explicit routing policy, without requiring an API account to start. Returns compact multi-source results that preserve provenance, provider failures, and bounded evidence budgets so agents can inspect how each result was found.

Enables English and Chinese web search without an API key, returning compact multi-source evidence with provenance, visible provider failures, and bounded request and evidence budgets, while optionally using paid providers under an explicit policy.

Enables English and Chinese web search without an API key using zero-key sources, returning compact multi-source evidence with inspectable routing, budgets, and provider failures; optional paid providers can be enabled under policy.

Enables AI agents to run English and Chinese web searches without any API key, returning compact multi-source evidence with provenance and preserving provider failures in the response. It also caps adapter attempts, elapsed time, and response tokens, and can optionally escalate to paid providers under an explicit routing policy.

Integrates the Brave Search API to provide comprehensive web and local search capabilities. It enables users to perform general web queries, search for news, and find local business information with smart fallback functionality.
