## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `BLITZ_API_ENRICH_COMPANY` | Enrich Company | Retrieve a full company profile from an exact LinkedIn company page URL. A successful match consumes record credits. |
| `BLITZ_API_FIND_COMPANIES_HIRING` | Find Companies Hiring | Find distinct companies hiring for matching jobs and return each company's matched-job count. Returns one metered page and an opaque continuation cursor. |
| `BLITZ_API_FIND_WORK_EMAIL` | Find Work Email | Retrieve a verified work email for a person identified by LinkedIn profile URL. A successful match consumes record credits. |
| `BLITZ_API_GET_API_KEY_DETAILS` | Get API Key Details | Validate the connected BlitzAPI key and return its record balance, per-endpoint rate limit, allowed API routes, and active plans. |
| `BLITZ_API_GET_CHANGELOG` | Get Changelog | Return recent public BlitzAPI changelog entries newest first, optionally limited by age and count. |
| `BLITZ_API_GET_COMPANY_EMPLOYEE_DISTRIBUTION` | Get Company Employee Distribution | Return a company's employee counts and percentages grouped by country or department; each call consumes record credits. |
| `BLITZ_API_LIST_COMPANY_EMPLOYEES` | List Company Employees | Browse employees at one exact LinkedIn company using location, seniority, department, and connection-count filters. Returns one metered page and an opaque continuation cursor; unlike broad Search People, this action preserves BlitzAPI's one-company page browsing contract. |
| `BLITZ_API_RESOLVE_DOMAIN_TO_LINKEDIN_COMPANY` | Resolve Domain to LinkedIn Company | Resolve a website domain or URL to its primary LinkedIn company page and possible alternatives. A successful match consumes record credits. |
| `BLITZ_API_RESOLVE_LINKEDIN_COMPANY_TO_DOMAIN` | Resolve LinkedIn Company to Domain | Resolve a LinkedIn company page URL to its canonical email domain. A valid lookup with no match returns found=false and email_domain=null; a successful match may consume record credits. |
| `BLITZ_API_RESOLVE_PERSON` | Resolve Person | Resolve a verified work email or US phone number in E.164 format to a full professional profile. Phone lookup is US-only and requires a paid-plan route entitlement. A valid no-match returns found=false and person=null; a successful match consumes 1 record credit. |
| `BLITZ_API_SEARCH_COMPANIES` | Search Companies | Search companies by firmographics, funding, traffic, keywords, and headquarters criteria; returns one metered page and an opaque continuation cursor. |
| `BLITZ_API_SEARCH_COMPANY_JOBS` | Search Company Jobs | List live job postings for one exact LinkedIn company, optionally filtered by job attributes; return one metered page with a continuation cursor. |
| `BLITZ_API_SEARCH_JOBS` | Search Jobs | Search live job postings by role, description, semantic keywords, recency, location, and company criteria; return one metered page with a continuation cursor. |
| `BLITZ_API_SEARCH_PEOPLE` | Search People | Search professional profiles across one or more companies using person, role, location, education, and firmographic filters. Returns one metered page and an opaque continuation cursor. |
| `BLITZ_API_WATERFALL_ICP_SEARCH` | Waterfall ICP Search | Find and rank decision-makers at one company using an ordered cascade of title and location rules; successful results consume record credits. |

```python
pip install composio_openai
```

```typescript
npm install @composio/openai
```

#### Path 1, Step 2: Initialize Composio and Create Tool Router Session

Import and initialize Composio client, then create a Tool Router session
```python
from openai import OpenAI
from composio import Composio
from composio_openai import OpenAIResponsesProvider

composio = Composio(provider=OpenAIResponsesProvider())
openai = OpenAI()
session = composio.create(user_id='your-user-id')
```

import OpenAI from 'openai';
import { Composio } from '@composio/core';
import { OpenAIResponsesProvider } from '@composio/openai';

const composio = new Composio({
  provider: new OpenAIResponsesProvider(),
});
const openai = new OpenAI({});
const session = await composio.create('your-user-id');
```

#### Path 1, Step 3: Execute Blitz API Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Blitz API actions with your Agent
```python
tools = session.tools
response = openai.responses.create(

  tools=tools,
  input=[{
    'role': 'user',
    'content': 'YOUR_SPECIFIC_PROMPT_HERE'
  }]
)
result = composio.provider.handle_tool_calls(
  response=response,
  user_id='your-user-id'
)
print(result)
```

```typescript
const tools = session.tools;
const response = await openai.responses.create({
  model: 'gpt-4.1',
  tools: tools,
  input: [{
    role: 'user',
    content: 'YOUR_SPECIFIC_PROMPT_HERE'
  }],
});
const result = await composio.provider.handleToolCalls(
  'your-user-id',

#### Path 2, Step 3: Connect to AI Agent

Use the MCP server with your AI agent (Anthropic Claude or Mastra)
```python
import asyncio

options = ClaudeAgentOptions(
    permission_mode='bypassPermissions',
    mcp_servers={
        'tool_router': {
            'type': 'http',
            'url': url,
            'headers': {
                'x-api-key': 'your-composio-api-key'
            }
        }
    },
    system_prompt='You are a helpful assistant with access to Blitz API tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('YOUR_SPECIFIC_PROMPT_HERE')
        async for message in client.receive_response():
            if hasattr(message, 'content'):
                for block in message.content:
                    if hasattr(block, 'text'):
                        print(block.text)

asyncio.run(main())
```

```typescript
import { openai } from '@ai-sdk/openai';
import { experimental_createMCPClient as createMCPClient } from '@ai-sdk/mcp';
import { generateText } from 'ai';

const client = await createMCPClient({
  transport: {
    type: 'http',
    url: session.mcp.url,
    headers: {
      'x-api-key': 'your-composio-api-key',
    },
  },
});

const tools = await client.tools();
const { text } = await generateText({
  model: openai('gpt-4o'),
  tools,
  messages: [{
    role: 'user',
    content: 'YOUR_SPECIFIC_PROMPT_HERE'
  }],
  maxSteps: 5,
});

console.log(`Agent: ${text}`);
```
