```bash\r
openclaw skills install exa-search\r
```\r
\r
### Step 4: Use Skill (1 minute)\r
```typescript\r
const result = await agent.run('exa-search', {\r
  query: 'transformer architecture improvements',\r
  category: 'research paper',\r
  start_published_date: '2024-01-01',\r
  end_published_date: '2024-03-31',\r
  search_type: 'neural',\r
  num_results: 5\r
});\r
\r
console.log(`Found ${result.result_count} papers`);\r
result.results.forEach(paper => {\r
  console.log(`${paper.title} (${paper.published_date})`);\r
});\r
```\r
\r
## Real-World Use Cases\r
\r
### Scenario 1: Academic Research\r
**Problem**: Find transformer papers from Q1 2024\r
**Solution**: Use precise date filtering + research paper category\r
**Example**:\r
```typescript\r
{\r
  query: "transformer architecture improvements",\r
  category: "research paper",\r
  start_published_date: "2024-01-01",\r
  end_published_date: "2024-03-31"\r
}\r
```\r
\r
### Scenario 2: GitHub Discovery\r
**Problem**: Find Rust web frameworks created in 2024\r
**Solution**: Use GitHub category + date filtering\r
**Example**:\r
```typescript\r
{\r
  query: "rust web framework",\r
  category: "github",\r
  start_published_date: "2024-01-01"\r
}\r
```\r
\r
### Scenario 3: Competitive Analysis\r
**Problem**: Find similar companies in AI agent space\r
**Solution**: Use company category + domain exclusion\r
**Example**:\r
```typescript\r
{\r
  query: "AI agent platforms",\r
  category: "company",\r
  exclude_domains: ["competitor.com"]\r
}\r
```\r
\r
## Integration Recipes\r
\r
### OpenClaw Agent\r
```typescript\r
import { Claw0xClient } from '@claw0x/sdk';\r
\r
const claw0x = new Claw0xClient(process.env.CLAW0X_API_KEY);\r
\r
const papers = await claw0x.call('exa-search', {\r
  query: 'large language model reasoning',\r
  category: 'research paper',\r
  start_published_date: '2024-01-01',\r
  search_type: 'neural'\r
});\r
```\r
\r
### LangChain Agent\r
```python\r
from claw0x import Claw0xClient\r
\r
client = Claw0xClient(api_key=os.environ['CLAW0X_API_KEY'])\r
\r
repos = client.call('exa-search', {\r
    'query': 'rust web framework',\r
    'category': 'github',\r
    'start_published_date': '2024-01-01'\r
})\r
```\r
\r
### Custom Agent\r
```javascript\r
const response = await fetch('https://api.claw0x.com/v1/call', {\r
  method: 'POST',\r
  headers: {\r
    'Authorization': `Bearer ${process.env.CLAW0X_API_KEY}`,\r
    'Content-Type': 'application/json'\r
  },\r
  body: JSON.stringify({\r
    skill: 'exa-search',\r
    input: {\r
      query: 'AI regulation news',\r
      category: 'news',\r
      start_published_date: '2024-03-15',\r
      end_published_date: '2024-03-22'\r
    }\r
  })\r
});\r
