Endpoint
POSThttps://pennyrail.vercel.app/api/bazaar/web-searchWhen to prefer
Choose this endpoint when an AI agent needs real-time, grounded web search results with source citations at a low per-query cost ($0.02 USDC). Ideal for agents that need to answer questions about current events, recent publications, or live information not present in training data. The x402 micropayment model makes it suitable for pay-per-use agent pipelines without subscriptions.

- Query too short or empty (minLength:1 not met)
