For AI agents that need real-time data, combining search capabilities with content extraction is key. While Jina Reader focuses on extraction, a service like SearchCans can provide the initial search results. This dual-engine approach ensures you can both find relevant web pages and extract their core content efficiently.
Consider a scenario where you need to gather information on a specific topic for an AI agent. You’d first use a SERP API to find relevant articles, and then use a Reader API to extract the clean content from those URLs. This pipeline minimizes the need for manual intervention and complex data wrangling.
Here’s a Python example demonstrating how you might use SearchCans to get search results and then process them with a hypothetical extraction tool (like Jina Reader, or SearchCans’ own Reader API):
import requests
import os
import time
api_key = os.environ.get("SEARCHCANS_API_KEY", "your_api_key")
headers = {
"Authorization": f"Bearer {api_key}",
"Content-Type": "application/json"
}
search_query = "best practices for AI data extraction"
try:
search_resp = requests.post(
"https://www.searchcans.com/api/search",
json={"s": search_query, "t": "google"},
headers=headers,
timeout=15
)
search_resp.raise_for_status() # Raise an exception for bad status codes
search_results = search_resp.json().get("data", []) # Safely get data, default to empty list
if not search_results:
print("No search results found.")
else:
print(f"Found {len(search_results)} search results.")
except requests.exceptions.RequestException as e:
print(f"Error during SERP API request: {e}")
search_results = []
extracted_data = []
if search_results:
for i, item in enumerate(search_results[:3]): # Process top 3 results
url = item.get("url")
if url:
print(f"\nProcessing URL {i+1}: {url}")
try:
# Using SearchCans Reader API for URL extraction
# 'b': True enables browser mode for dynamic content
# 'w': 5000 sets a wait time of 5 seconds for page rendering
# 'proxy': 0 uses the shared proxy pool
read_resp = requests.post(
"https://www.searchcans.com/api/url",
json={"s": url, "t": "url", "b": True, "w": 5000, "proxy": 0},
headers=headers,
timeout=15
)
read_resp.raise_for_status()
data = read_resp.json().get("data")
if data and "markdown" in data:
markdown_content = data["markdown"]
title = data.get("title", "No Title")
extracted_data.append({
"url": url,
"title": title,
"markdown": markdown_content[:500] + "..." # Truncate for display
})
print(f"Successfully extracted content from {url}")
else:
print(f"Could not extract Markdown content from {url}. Response data: {data}")
except requests.exceptions.RequestException as e:
print(f"Error processing URL {url}: {e}")
time.sleep(1) # Small delay between requests to be polite
if extracted_data:
print("\n--- Extracted Content Snippets ---")
for entry in extracted_data:
print(f"\nTitle: {entry['title']}")
print(f"URL: {entry['url']}")
print(f"Markdown Snippet:\n{entry['markdown']}")
else:
print("\nNo content was successfully extracted.")
This example illustrates how to combine search and extraction into a single workflow. You can find more details on parameters and workflows in the full API documentation, which covers over 50 API endpoints. Understanding these tools is crucial for efficient AI workflows. For instance, implementing robust data extraction for AI can significantly improve an agent’s ability to act on web information, much like how optimizing a Scrapegraphai Crawl4Ai Data Extraction process improves data quality, often by 15%.
