Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/premium/web.search--searchWhen to prefer
Choose this endpoint when an agent needs live, up-to-date web search results that are beyond its training data cutoff. It is suitable for retrieving current news, verifying recent facts, or discovering URLs about any topic. Prefer this over static knowledge bases when freshness is critical. The x402 micropayment model at $0.02 per call makes it cost-effective for moderate query volumes without subscription commitments.

- Malformed input object missing required fields — returns 400 Bad Request
- Query too vague or empty — may return empty result set
- Rate limiting or service unavailability on Vercel infrastructure — returns 503
