Real-World Use Cases#

Scenario 1: Academic Research#

Problem: Find transformer papers from Q1 2024 Solution: Use precise date filtering + research paper category Example:

typescript

{
  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:

typescript

{
  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:

typescript

{
  query: "AI agent platforms",
  category: "company",
  exclude_domains: ["competitor.com"]
}

Integration Recipes#

OpenClaw Agent#

typescript

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#

python

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#

javascript

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'
    }
  })
});
