Integration

Production-grade integration

Drop-in OpenAI SDK replacement. Python, Node, Go, Rust — if it speaks HTTP, it works.

example.py Python 
from openai import OpenAI

client = OpenAI(
    base_url="https://api.verticalapi.com/v1",
    api_key="your-verticalapi-key",
    default_headers={"X-Provider-Key": "sk-ant-..."}
)

response = client.chat.completions.create(
    model="copywriter",  # or any of 76 verticals
    messages=[{"role": "user", "content": "Write a tagline for my app"}]
)

print(response.choices[0].message.content)
IDE Integration

Native IDE intelligence

Plug 76 domain experts directly into Claude Desktop, Cursor, VS Code, or Windsurf via MCP. One config.

⚡
Claude Desktop
Add to your claude_desktop_config.json:
// ~/Library/.../claude_desktop_config.json { "mcpServers": { "verticalapi": { "command": "npx", "args": ["-y", "verticalapi-mcp"], "env": { "VERTICALAPI_KEY": "vapi_...", "PROVIDER_KEY": "sk-ant-..." } } } }
🛠
Cursor / VS Code
Add to .cursor/mcp.json or .vscode/mcp.json:
// .cursor/mcp.json { "mcpServers": { "verticalapi": { "command": "npx", "args": ["-y", "verticalapi-mcp"], "env": { "VERTICALAPI_KEY": "vapi_...", "PROVIDER_KEY": "sk-ant-..." } } } }
🎯
Then just ask
All 76 verticals become tools in your AI assistant:
"Review this code for security issues" → code-reviewer vertical activates "Write copy for my landing page" → copywriter vertical activates "Analyze this quarterly report" → financial-analyst vertical activates
