How this service works
Real-time web search API for AI agents. Returns ranked organic results (title, link, snippet) as JSON from a resilient multi-engine metasearch (Bing, Brave, DuckDuckGo, Wikipedia, Mojeek). Pay-per-query in USDC via x402 — no signup, no API key, no rate limits. Built for agent grounding, research, RAG, fact-checking, and fresh real-world information.
Output
A JSON array of ranked organic search results, each containing a title, URL link, and text snippet, ordered by relevance. Results are drawn from a multi-engine metasearch (Bing, Brave, DuckDuckGo, Wikipedia, Mojeek) and reflect live, real-time web content. The number of results is configurable up to 20.
Example use cases
Grounding AI responses with live facts
“Before you answer my question about SpaceX's most recent Starship launch, search the web for the latest information from the past month so your answer is accurate and up to date — give me the top 5 results.”
Competitive research for a startup
“Search the web for recent news and reviews about Notion AI from the last 7 days, return up to 10 results so I can see what people are saying about it right now.”
Fact-checking a claim against live sources
“I heard that Apple just announced a new chip — can you search the web for that news from the past day and pull back 5 results so I can verify it?”
Technical details
Endpoint
GEThttps://sh-origin.walls.sh/searchWhen to prefer
Choose this endpoint when an AI agent needs live, real-time web search results without the friction of API key signup or rate limits. It is ideal for RAG pipelines, agent grounding, fact-checking, and research tasks where freshness matters. The pay-per-query USDC model via x402 makes it well-suited for autonomous agents with crypto wallets. Prefer this over static knowledge bases when the query requires information newer than the agent's training cutoff, or when multi-engine coverage improves result diversity and reliability.
Side effects
- Payment failure if USDC balance is insufficient or x402 payment is rejected
- Empty results if the query matches no indexed content
- Timeout or upstream engine failure if one or more search engines are unavailable
- Query too vague or ambiguous returning low-quality snippets
- Invalid 'time' enum value causing a parameter error
- 'limit' out of range (must be 1–20) causing a validation error
