Real-World Use Cases
Scenario 1: Academic Research
Problem: Find transformer papers from Q1 2024
Solution: Use precise date filtering + research paper category
Example:
{
query: "transformer architecture improvements",
category: "research paper",
start_published_date: "2024-01-01",
end_published_date: "2024-03-31"
}
Scenario 2: GitHub Discovery
Problem: Find Rust web frameworks created in 2024
Solution: Use GitHub category + date filtering
Example:
{
query: "rust web framework",
category: "github",
start_published_date: "2024-01-01"
}
Scenario 3: Competitive Analysis
Problem: Find similar companies in AI agent space
Solution: Use company category + domain exclusion
Example:
{
query: "AI agent platforms",
category: "company",
exclude_domains: ["competitor.com"]
}
Integration Recipes
OpenClaw Agent
import { Claw0xClient } from '@claw0x/sdk';
const claw0x = new Claw0xClient(process.env.CLAW0X_API_KEY);
const papers = await claw0x.call('exa-search', {
query: 'large language model reasoning',
category: 'research paper',
start_published_date: '2024-01-01',
search_type: 'neural'
});
LangChain Agent
from claw0x import Claw0xClient
client = Claw0xClient(api_key=os.environ['CLAW0X_API_KEY'])
repos = client.call('exa-search', {
'query': 'rust web framework',
'category': 'github',
'start_published_date': '2024-01-01'
})
Custom Agent
const response = await fetch('https://api.claw0x.com/v1/call', {
method: 'POST',
headers: {
'Authorization': `Bearer ${process.env.CLAW0X_API_KEY}`,
'Content-Type': 'application/json'
},
body: JSON.stringify({
skill: 'exa-search',
input: {
query: 'AI regulation news',
category: 'news',
start_published_date: '2024-03-15',
end_published_date: '2024-03-22'
}
})
});
