## When to prefer this

Choose this endpoint when an AI agent needs real-time web search results and is operating in an x402/USDC micropayment environment. Prefer over alternatives when the agent already handles x402 payment flows, needs Tavily-quality search results, or is integrated into the402.ai marketplace ecosystem. Ideal for agents that need up-to-date information beyond their training cutoff.

## Known failure modes

- Insufficient USDC balance or failed x402 payment — payment authorization error
- Invalid or missing search query — 400 bad request
- Tavily backend unavailable — upstream service error or timeout
- Rate limiting on the402.ai platform — 429 too many requests
- Malformed x402 payment header — payment rejected before search executes
