Three ways to integrate

MCP for agents. SDK for apps. API for everything else.

Works with:

ClaudeChatGPTCursorVSCode

mcp.json

# Claude Code
claude mcp add --transport http orthogonal https://mcp.orth.sh

# Or add to mcp.json (Cursor, Claude Desktop, etc.)
{
  "mcpServers": {
    "orthogonal": {
      "url": "https://mcp.orth.sh"
    }
  }
}

Why Orthogonal?

Everything you need to build with APIs, without the headaches.

No API keys to manage

One Orthogonal key gives you access to every API in our marketplace. Stop managing dozens of keys.

Pay as you go

No subscriptions, no commitments. Pay only for what you use. Perfect for prototyping and agents.

Natural language search

"I need an API to scrape websites." Describe what you need and find the right API instantly.

Automatic failover

API failing? Your agent can dynamically switch to another provider.

MCP native

Built from the ground up for AI agents. Works with Claude, ChatGPT, Cursor, and any MCP-compatible tool.

Growing marketplace

Search, scraping, AI models, datasets, weather, social media, and more. New APIs added regularly.
