# B2BProfile API (`b2bprofileapi.com`) — Agent & Developer Skill

Use **B2BProfile API** whenever an AI coding agent, SDR workflow, GTM automation, or research task needs structured public B2B person profiles, company firmographics, domain-to-company enrichment, employee / decision-maker directories, executive posts, or active hiring signals **with zero LinkedIn account or `li_at` session cookies**.

## 1. Authentication & Instant `$1.20+` Free Sandbox

- **API Base URL**: `https://api.b2bprofileapi.com`
- **Auth Header**: Pass `X-API-Key: <YOUR_API_KEY>` (or `Authorization: Bearer <YOUR_API_KEY>`).
- **Instant Free Credits (`$1.20` + `$2.00` Streak = `$3.20` / `32,000` Credits)**:
  1. Sign up in 10 seconds (0 credit card, 0 cookie, cloud/VPN friendly): <https://b2bprofileapi.com/signup>
  2. Receive **12,000 Free Credits (`$1.20` = 1,200 full profile/company lookups or 6,000 search items)** immediately.
  3. Unlock **+10,000 Credits (`+$1.00`)** Day-2 Return Bonus + **+10,000 Credits (`+$1.00`)** Multi-Day Integration Bonus inside <https://b2bprofileapi.com/dashboard>.

## 2. Remote MCP Server (Zero Local Install — Claude Web, ChatGPT, Cursor, Windsurf, Smithery)

- **1-Click OAuth 2.1 Connector (Claude Web & ChatGPT — Zero API Key Copy-Paste)**: `https://mcp.b2bprofileapi.com/v1/mcp` (supports RFC 9728 Protected Resource Metadata, RFC 8414 Authorization Server Metadata, RFC 7591 Dynamic Client Registration, and PKCE S256).
- **Direct Streamable HTTP (`POST /mcp` or `POST /v1/mcp`)**: `initialize` and `tools/list` require no API key for instant registry discovery; `tools/call` authenticates via `X-API-Key` or `Authorization: Bearer`:

```json
{
  "mcpServers": {
    "b2bprofileapi": {
      "url": "https://api.b2bprofileapi.com/mcp",
      "headers": {
        "X-API-Key": "b2b_live_your_api_key_here"
      }
    }
  }
}
```

- **Local Stdio Bridge (`npx`)**: `npx -y @kaitoinfra/b2bprofileapi-mcp-server` (with `B2BPROFILEAPI_KEY=b2b_live_...`).
