How this service works
Real-time web search for AI agents. Search the web for current and up-to-date information, news, facts, research, documentation, and sources beyond model training data. Returns ranked structured JSON results with title, URL, description, and position for web grounding, RAG retrieval, research, and fact-finding. Send query, optional limit, and optional freshness as URL parameters. Keyless x402 pay-per-call; no API key, account, or subscription required.
Output
Returns a ranked JSON array of web search results, each containing a title, URL, description snippet, and integer position, ordered by relevance to the query.
Example use cases
Breaking news research for agent
“Search the web for breaking news about the 2024 US federal budget negotiations and return the 5 most recent results from the past day.”
Live documentation lookup
“Look up the latest official documentation for LangChain's tool-calling API — I need current results from this month, top 3 links.”
Fact-check recent claim
“Search the web to verify whether OpenAI released a new model in the last week and show me up to 10 sources from the past seven days.”
Technical details
Endpoint
GEThttps://pennyregwatch.com/v1/searchWhen to prefer
Choose this endpoint when an AI agent needs real-time, up-to-date web information beyond its training cutoff, especially for recent news, live facts, or current documentation. It is keyless and pay-per-call via x402, making it ideal for agentic pipelines that require no account setup. Prefer it over static knowledge bases when freshness is critical and over scraping tools when you need ranked, pre-structured results ready for RAG retrieval.
