Give them live web access through one REST call: structured JSON results ready for any LLM context window. 50M+ API requests served 99.9% Uptime SLA 100+ Countries supported <5s Median response time Capabilities ## What you can build with a search-enabled agent The [Web Search API](https://www.serphouse.com/web-search-api) gives your agents a live window into the world. Here is what that unlocks. Tool & Function Calling Register SERPHouse as a tool in OpenAI function calling, Anthropic tool use, or any agent framework. One function definition gives your agent instant web access. Hallucination Prevention Force agents to search before they answer. Ground every response in current, verified web data instead of training memory from months ago. Multi-Step Research Chain searches in an agent loop. Each result informs the next query. Build agents that conduct deep, systematic research across multiple sources. Always Current Knowledge No knowledge cutoff. No stale context. Your agent searches the live web and knows what happened today. Parallel Search Execution Run multiple search queries concurrently in async agent pipelines. Surface broad context across topics, regions, and sources in a single agent turn. Structured LLM-Ready Output Every result returns `position`, `title`, `url` and `snippet`. Drops directly into your prompt, with no HTML parsing or preprocessing required. How It Works ## From zero to a grounded AI agent in 4 steps 1 Get your API key Sign up free at SERPHouse. No credit card required. Copy your API key from the dashboard in under 2 minutes. 2 Register as an agent tool Define a search function that calls the SERPHouse REST API. Pass it to your agent framework as a tool or function that works with OpenAI, Anthropic, LangChain, LlamaIndex, LangGraph, CrewAI, and AutoGen. 3 Agent triggers a search When the agent needs current information, it calls the search tool with a query. The API responds in under 1 second with structured JSON including organic results, each with `position`, `title`, `url` and `snippet`. 4 Ground the LLM response Inject the search results into the LLM system prompt as context. The model reasons over real data, not hallucinated training memory. Why grounding matters Without grounding - Agent answers from training data with a knowledge cutoff - Hallucination risk on recent events or current facts - No citations, user cannot verify the source With SERPHouse grounding - Agent retrieves live facts before responding - Accurate, current, and citable answers - URLs returned with each result, resulting in fewer hallucinations, better trust **Result:** Fewer hallucinations, better user trust, and citable search results with real URLs your users can verify. Code Examples ## Register search as an agent tool in minutes One REST endpoint. Standard bearer auth. The structured JSON response drops directly into your agent context with no transformation required. Works with OpenAI, Anthropic Claude, LangChain, LlamaIndex, LangGraph, CrewAI, and AutoGen. `GET /serp/live` · REST endpoint, no SDK needed `Authorization: Bearer` · Standard bearer token auth `results.organic[]` · position,title, link, snippet per result import requests from openai import OpenAI def search\_web(query, num\_result=5): """Search the live web; register this as an AI agent tool.""" response = requests.get( "https://api.serphouse.com/serp/live", headers={"Authorization": "Bearer YOUR\_API\_KEY"}, params={"q": query, "loc": "United+States", "num\_result": 5} ) return response.json()\["results"\]\["organic"\] \# Register with OpenAI function calling client = OpenAI() tools = \[{ "type": "function", "function": { "name": "search\_web", "description": "Search the live web for current information.", "parameters": { "type": "object", "properties": { "query": {"type": "string", "description": "The search query"}, "num\_result": {"type": "integer", "default": 5} }, "required": \["query"\] } } }\] response = client.chat.completions.create( model="gpt-4o", messages=\[{"role": "user", "content": "Latest AI agent frameworks in 2025?"}\], tools=tools, tool\_choice="auto" ) [Try it live in the API Playground →](https://www.serphouse.com/serp-api-playground) Why SERPHouse ## One search API. Every agent framework. Most web search APIs are designed for traditional applications. SERPHouse is built with AI agent pipelines in mind: structured JSON output, sub-second latency, and 100+ country targeting means your agents can research any topic, in any region, without specialized infrastructure. ![check](https://www.serphouse.com/images/homePage/serp-description-icon.png) Works with OpenAI, Anthropic, Google Gemini function calling ![check](https://www.serphouse.com/images/homePage/serp-description-icon.png) Compatible with LangChain, LlamaIndex, LangGraph, CrewAI, AutoGen ![check](https://www.serphouse.com/images/homePage/serp-description-icon.png) REST API: no SDK required, any HTTP client works ![check](https://www.serphouse.com/images/homePage/serp-description-icon.png) Async-ready for concurrent multi-query agent turns ![check](https://www.serphouse.com/images/homePage/serp-description-icon.png) Production SLA: 99.9% uptime with automatic retry handling OpenAI Register as a function tool in gpt-4o, o3, or any OpenAI model.
