🛠 Getting Started with Brave Search API

Setting Up Your API Access

To begin using the Brave Search API, follow these steps:

Create a Brave Developer Account Visit the Brave Search API portal and sign up for a developer account.
Choose Your Plan Start with the free tier (1 query/second, 2,000 queries/month) or select a paid plan based on your needs.
Generate API Keys Once registered, generate your API keys from the developer dashboard.
Install Required Libraries For Python users (which we'll use for examples), install the requests library:

pip install requests

Basic API Query Example

Let's start with a simple query to understand the API response format:

import requests
import json
 
API_KEY = "your_api_key_here"
ENDPOINT = "https://api.search.brave.com/res/v1/web/search"
 
headers = {
    "Accept": "application/json",
    "Accept-Encoding": "gzip",
    "X-Subscription-Token": API_KEY
}
 
params = {
    "q": "climate change research papers",
    "count": 10,
    "freshness": "month"
}
 
response = requests.get(ENDPOINT, headers=headers, params=params)
results = json.loads(response.text)
 
# Print the titles of the search results
for result in results.get('web', {}).get('results', []):
    print(result.get('title'))
    print(result.get('url'))
    print('-' * 50)

This basic example demonstrates how to make a search query and parse the results. The API returns a structured JSON response containing web results, which can be easily processed for various research automation tasks.

    response = requests.get(ENDPOINT, headers=headers, params=params)
    results = json.loads(response.text)
    
    # Extract descriptions to analyze common themes
    descriptions = [result.get('description', '') for result in results.get('web', {}).get('results', [])]
    
    # Simple keyword extraction (could be enhanced with NLP libraries)
    all_text = ' '.join(descriptions).lower()
    words = re.findall(r'\b[a-z]{4,15}\b', all_text)
    common_words = Counter(words).most_common(10)
    
    return {
        'results': results.get('web', {}).get('results', []),
        'common_themes': common_words
    }
 
# Example usage

import requests
import json
import os
import time
 
def collect_training_data(topics, samples_per_topic=50):
    API_KEY = "your_api_key_here"
    ENDPOINT = "https://api.search.brave.com/res/v1/web/search"
    
    headers = {
        "Accept": "application/json",
        "Accept-Encoding": "gzip",
        "X-Subscription-Token": API_KEY
    }
    
    dataset = []
    
    for topic in topics:
        print(f"Collecting data for: {topic}")
        
        # We'll paginate through results to get more samples
        offset = 0
        topic_samples = 0
        
        while topic_samples < samples_per_topic:
            params = {
                "q": topic,
                "count": 20,
                "offset": offset
            }
            
            response = requests.get(ENDPOINT, headers=headers, params=params)
            results = json.loads(response.text)
            
            for result in results.get('web', {}).get('results', []):
                dataset.append({
                    'topic': topic,
                    'title': result.get('title', ''),
                    'description': result.get('description', ''),
                    'url': result.get('url', '')
                })
                
                topic_samples += 1
                if topic_samples >= samples_per_topic:
                    break
            
            offset += 20
            time.sleep(1)  # Respect rate limits
    
    # Save the dataset
    with open('search_training_data.json', 'w') as f:
        json.dump(dataset, f, indent=2)
    
    return dataset
 
# Example usage
ai_topics = [
    "machine learning applications",
    "neural network architecture",
    "reinforcement learning examples",
    "natural language processing techniques",
    "computer vision algorithms"
]
 
training_data = collect_training_data(ai_topics, samples_per_topic=30)
print(f"Collected {len(training_data)} training samples across {len(ai_topics)} topics")

Leveraging Brave's AI-Enhanced Responses

Brave Search offers an "Answer with AI" feature that provides concise summaries with source references. We can use this in our applications:

import requests
import json
 
def get_ai_enhanced_answer(query):
    API_KEY = "your_api_key_here"
    ENDPOINT = "https://api.search.brave.com/res/v1/web/search"
    
    headers = {
        "Accept": "application/json",
        "Accept-Encoding": "gzip",
        "X-Subscription-Token": API_KEY
    }
    
    params = {
        "q": query,
        "count": 5,
        "features": "ai_answer"  # Request AI-enhanced answer
    }
    
    response = requests.get(ENDPOINT, headers=headers, params=params)
    results = json.loads(response.text)
    
    # Extract the AI answer when available
    ai_answer = results.get('ai_answer', {})
    
    if ai_answer:
        return {
            'summary': ai_answer.get('summary', ''),
            'sources': ai_answer.get('sources', [])
        }
    else:
        return {
            'summary': "No AI-enhanced answer available for this query.",
            'sources': []
        }
 
# Example usage
answer = get_ai_enhanced_answer("How does quantum computing differ from classical computing?")
print("AI-Enhanced Answer:")
print(answer['summary'])
print("\nSources:")
for source in answer['sources']:
    print(f"- {source.get('title')}: {source.get('url')}")

This approach allows you to provide users with concise, sourced information directly from Brave's AI capabilities, which can be particularly useful for educational applications, research tools, or content generation systems.

⚙️ Advanced API Features and Optimizations

# News-specific search
params = {
    "q": "artificial intelligence breakthroughs",
    "count": 10,
    "search_lang": "en",
    "result_filter": "news"
}
 
# Location-based search
params = {
    "q": "renewable energy projects",
    "count": 10,
    "country": "US",
    "city": "Boston"
}
 
# Time-based filtering
params = {
    "q": "covid research findings",
    "count": 10,
    "freshness": "month"  # Options: day, week, month, year
}

Rate Limit Management

To avoid hitting API limits, implement proper rate limiting in your application:

import time
import requests
from collections import deque
from datetime import datetime, timedelta
 
class RateLimitedAPI:
    def __init__(self, api_key, requests_per_second=1):
        self.api_key = api_key
        self.endpoint = "https://api.search.brave.com/res/v1/web/search"
        self.request_times = deque()
        self.requests_per_second = requests_per_second
        
    def search(self, query, **params):
        # Implement rate limiting
        self._enforce_rate_limit()
        
        headers = {
            "Accept": "application/json",
            "Accept-Encoding": "gzip",
            "X-Subscription-Token": self.api_key
        }
        
        search_params = {
            "q": query,
            **params
        }
        
        response = requests.get(self.endpoint, headers=headers, params=search_params)
        self.request_times.append(datetime.now())
        
        return response.json()
    
    def _enforce_rate_limit(self):
        """Ensure we don't exceed our rate limit"""
        now = datetime.now()
        
        # Remove timestamps older than 1 second
        while self.request_times and now - self.request_times[0] > timedelta(seconds=1):
            self.request_times.popleft()
        
        # If we've reached our limit, wait until we can make another request
        if len(self.request_times) >= self.requests_per_second:
            sleep_time = 1 - (now - self.request_times[0]).total_seconds()
            if sleep_time > 0:
                time.sleep(sleep_time)
 
# Example usage
api = R
