Capabilities
The 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
Get your API key
Sign up free at SERPHouse. No credit card required. Copy your API key from the dashboard in under 2 minutes.
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.
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.
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
With SERPHouse grounding
Result: Fewer hallucinations, better user trust, and citable search results with real URLs your users can verify.
Code Examples
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.

Why SERPHouse
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.
Works with OpenAI, Anthropic, Google Gemini function calling
Compatible with LangChain, LlamaIndex, LangGraph, CrewAI, AutoGen
REST API: no SDK required, any HTTP client works
Async-ready for concurrent multi-query agent turns
Production SLA: 99.9% uptime with automatic retry handling
OpenAI
Register as a function tool in gpt-4o, o3, or any OpenAI model. The structured JSON response maps directly to tool output for the model to reason over.
Anthropic Claude
Use as a tool in Claude 3/4 tool use API. Define the search tool schema once and handle the tool_use content block in your response loop.
LangChain / LlamaIndex
Subclass BaseTool in LangChain or create a custom LlamaIndex reader. See the full integration guide at LangChain Integration.
FAQ
Everything developers ask before adding web search to their AI agents.
Register a function that calls the SERPHouse REST API: GET https://api.serphouse.com/serp/live with your query and API key. Pass this function as a tool to your agent framework (OpenAI function calling, LangChain Tool, Anthropic tool use). When the agent needs current information, it calls the function and receives structured JSON results it can include in its response.
Yes. Define a Python or JavaScript function that makes a GET request to the SERPHouse API, then register it as a tool in your OpenAI client call using the tools parameter. When the model decides to search, it triggers your function and receives results as structured JSON (including title, link, snippet, and position) for each result.
Yes. The SERPHouse Web Search API is a standard REST endpoint that works with any tool use implementation. Define the tool schema in your Anthropic client call, implement the function to call the SERPHouse API, and handle the tool_use content block in the response.
Ground agent responses in live web data by requiring the agent to search before answering factual questions. When an agent retrieves current web results via SERPHouse and uses them as context, it generates answers based on real, citable information rather than training memory. This is especially important for time-sensitive queries, recent events, and rapidly changing facts.
The SERPHouse API returns results in under 5 seconds on average (median 48ms for simple queries). In an agent pipeline, this adds one network round trip per search. For async agents running parallel tool calls, multiple searches add no additional wall-clock time. The latency is negligible compared to the LLM inference time.
Each organic result includes: position (rank position), title (page title), url (full URL), snippet (text excerpt). These fields map directly to LLM context without any parsing or transformation.
SERPHouse rate limits depend on your plan. Free tier supports limited requests per month for testing. Paid plans support higher concurrency for production agent pipelines. For high-volume agent applications making dozens of searches per agent turn, enterprise plans provide dedicated rate limits and SLA-backed uptime. See pricing for details.
Yes. Pass the date_range parameter to filter by time range (such as date_range=h for the past hour, date_range=d for past 24 hours, date_range=w for past week. This is essential for agents that need breaking news, current prices, or recent events. Combine with the loc parameter for country-specific recency filtering).
