## When to prefer this

Choose this endpoint when an AI agent needs real-time web search results and wants to use Brave Search (privacy-focused, independent index) rather than Google. Ideal for agentic workflows where pay-per-use micropayment billing via x402 is preferred over subscription-based search APIs. Well-suited when the agent needs live, up-to-date information not available in its training data.

## Known failure modes

- Insufficient USDC balance or payment failure via x402 protocol
- Invalid or missing search query parameter
- Rate limiting if too many requests are submitted in quick succession
- Brave Search API downstream outage returning empty or error response
- Malformed request body resulting in 400 error
