AI Agent Integration
For AI and LLM applications, the search API needs to return clean, context-ready results. Here is how SearchHive SwiftSearch works with a LangChain-style agent:
import requests
def search_for_agent(query, api_key, num_results=5):
"""Search and return results formatted for LLM context."""
response = requests.get(
"https://api.searchhive.dev/v1/search",
headers={"Authorization": f"Bearer {api_key}"},
params={
"q": query,
"engine": "google",
"num": num_results,
"include_snippets": True
}
)
results = response.json()["data"]["results"]
context = []
for r in results:
context.append({
"title": r["title"],
"url": r["url"],
"snippet": r.get("snippet", ""),
"content": r.get("content", "")
})
return context
# Use in an AI agent pipeline
query = "What are the latest web scraping regulations in the EU?"
search_results = search_for_agent(query, "your-key")
# Feed to LLM
context_text = "\n\n".join([
f"Title: {r['title']}\nURL: {r['url']}\nSnippet: {r['snippet']}"
for r in search_results
])
# context_text goes into your LLM prompt as retrieved context
print(f"Retrieved {len(search_results)} results for agent context")
Recommendation
For most developers in 2026, the decision comes down to two factors: budget and use case.
Need search + scraping + research in one platform? SearchHive SwiftSearch is the obvious choice. At $49 for 100K credits, it is 5x cheaper than SerpAPI and includes ScrapeForge and DeepDive. Get started free.
Building an AI/RAG pipeline specifically? Tavily is optimized for this but expensive. SearchHive SwiftSearch achieves similar results at a lower price point with its snippet and content extraction.
Just need Google results with maximum SERP features? SerpAPI is the most comprehensive, but you pay for that completeness.
Want predictable flat-rate pricing? Brave Search API at $5/1K is simple and clean -- as long as you do not need Google specifically.
Whatever you choose, start with the free tier. Every API on this list offers some free credits. Test against your actual queries and response format requirements before committing to a paid plan. See SearchHive docs for integration guides and real-time search APIs compared.
