Web Search Brave

Web Search (Brave Search API)

Search the web using Brave's Search API. Returns web results with descriptions, optional extra snippets, and support for country/language targeting.

Note: This skill requires a Brave Search API key. For basic web search using the agent's built-in capability, see web-search. For AI-optimized results with relevance scores, see web-search-tavily.

When to Use This Skill

Use this skill when:

• You need to find current information not in your training data
• The user asks about recent events, news, or updates
• You need localized search results for a specific country or language
• You want a privacy-respecting search alternative
• Research requires real-time web data
• Keywords mentioned: search, look up, find online, current, latest, news

Do NOT use this skill when:

• Information is already in your knowledge base and doesn't need verification
• The user asks about historical facts that don't change
• You're working with local files or code (use other tools)
• A more specific skill exists for the task (e.g., documentation lookup)
• You need AI-generated answer summaries (use web-search-tavily instead)

Common Issues and Solutions

Issue: "BRAVE_API_KEY environment variable is not set"

Symptoms: Script exits immediately with API key error

Solution:

• Get an API key from https://brave.com/search/api/
• Set the environment variable:

   export BRAVE_API_KEY="your-api-key-here"

• Or run with the variable inline:

   BRAVE_API_KEY="your-key" deno run --allow-env --allow-net=api.search.brave.com scripts/search.ts "query"

Issue: "Invalid Brave Search API key"

Symptoms: 401 authentication error

Solution:

• Verify your API key is correct (no extra spaces)
• Check if your API key has expired
• Verify your Brave Search API subscription is active

Symptoms: 429 error response

Solution:

• Wait a moment and retry
